  • 11.10 liveCD black screen

    - by Shaun Killingbeck
    Attempting to install/try ubuntu 11.10 on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. I have caught a glimpse of some output to do with pulseaudio and [fail], but I can't imagine why that would cause a screen problem and the sound definitely works anyway.

  • Windows Metro Requests

    - by Scott Dorman
    Windows 8 and Windows Metro style apps have a lot of potential, but only if application vendors realize there is a demand to see their app as a Metro style app and not just as a desktop app (or worse, only as an Android or iOS app). As consumers, the only thing we can do is be vocal about our desire to see these apps on Windows 8 as a Metro style app. In an effort to raise awareness, I just launched WinMetro Requests. This is our opportunity to request Windows Metro style apps  and show those companies just how much interest there is for seeing their app as a Metro style app. This site is running on UserVoice, so it allows you to easily submit application requests, add comments, and, more importantly, vote for your favorite applications to come to Windows as a Metro style app! As I find out the status of requested applications, I will update the status of the request. If you know and have official communication from one of the companies indicating they will be or are working on a Windows Metro style app, please let me know and I'll update the status of the request after verifying (or at least trying to verify) the information.

I see a lot of these questions as closed and there is no real answer given I will try any solutions available and report results so that others can also solve problems not be overwhelmed by overly broad troubleshooting guides that do nothing to help solve specific issues The nomodeset change from quiet splash also yields no results on reboot I still get a blank screen this screen still has contorl alt f1 abilities but that is it contorl alt f8 causes blinking cursor and F7 gets a crazy flash with green and blue then blank screen Contorl alt f1 a log in prompt in text only when run in recovery mode with failsafe graphics its says the syestem is running in low graphics mode your screen graphics card and input device settings could not be detected correctly. You will need to configure these your self how do i do that? I got this /var/log/failsafeX-backup-120909200641.tar as the location of my log files but i have no idea how to axcess sounds work in blank screen also screen responds or flashes after log in is typed and password entered really any help is good I don't even know where to start I believe 12.04 is installed and functioning but i don't think I can see it at the end of the error log it says error setting mtrr (base= oxf0000000, size= 0x01000000, type=1) inappropriate ioctl for device(25) i have tried to provide as much info as I understand how to provide

  • Black Screen when Computer Boots

    - by BlueRaja
    I'm having a serious problem with my computer; I think I've narrowed it down to the motherboard, but I'd like a second opinion before I spend the money. Before I moved into my new apartment, my desktop was working fine; now, it just won't work. It will turn on, the fans will spin up, lights come on... but nothing appears on the screen. No POST, nothing. I've tried: A different monitor (both are VGA) A different video-card (both are DVI, PCIe) Three different, known-good VGA-DVI adapters The onboard video port (VGA) Reseating the memory, and trying only one stick Different, known-good wall-outlets Unplugging the HDD and CD-drive from both the motherboard and PSU Replacing the PSU Has anyone had this happen before? Perhaps it's a known problem with this motherboard? Any advice!? Here are my specs: A13G+ V3.0 motherboard 2 2-gig 800mhz DDR2 600-watt PSU two older Geforce video cards

  • background screen recording tool

    - by misha nesterenko
    I am searching for a tool that allows background recording of my pc screen. I it is nothing like a spy tool, I just need to be able to check what I was doing at the some time in the past. Small impact on the system, and relatively small size of recordings, as it is supposed to run all time pc is turned on. Some recording management as auto pruning of recordings older than x days. UPD This is not a problem if some scripting is necessary to achieve what is described in the question. So it could be a command line recording tool which could be used from batch, bash (cygwin, mingw) scripts.

  • Azure WNS to Win8 - Push Notifications for Metro Apps

    - by JoshReuben
    Background The Windows Azure Toolkit for Windows 8 allows you to build a Windows Azure Cloud Service that can send Push Notifications to registered Metro apps via Windows Notification Service (WNS). Some configuration is required - you need to: Register the Metro app for Windows Live Application Management Provide Package SID & Client Secret to WNS Modify the Azure Cloud App cscfg file and the Metro app package.appxmanifest file to contain matching Metro package name, SID and client secret. The Mechanism: These notifications take the form of XAML Tile, Toast, Raw or Badge UI notifications. The core engine is provided via the WNS nuget recipe, which exposes an API for constructing payloads and posting notifications to WNS. An application receives push notifications by requesting a notification channel from WNS, which returns a channel URI that the application then registers with a cloud service. In the cloud service, A WnsAccessTokenProvider authenticates with WNS by providing its credentials, the package SID and secret key, and receives in return an access token that the provider caches and can reuse for multiple notification requests. The cloud service constructs a notification request by filling out a template class that contains the information that will be sent with the notification, including text and image references. Using the channel URI of a registered client, the cloud service can then send a notification whenever it has an update for the user. The package contains the NotificationSendUtils class for submitting notifications. The Windows Azure Toolkit for Windows 8 (WAT) provides the PNWorker sample pair of solutions - The Azure server side contains a WebRole & a WorkerRole. The WebRole allows submission of new push notifications into an Azure Queue which the WorkerRole extracts and processes. Further background resources: http://watwindows8.codeplex.com/ - Windows Azure Toolkit for Windows 8 http://watwindows8.codeplex.com/wikipage?title=Push%20Notification%20Worker%20Sample - WAT WNS sample setup http://watwindows8.codeplex.com/wikipage?title=Using%20the%20Windows%208%20Cloud%20Application%20Services%20Application – using Windows 8 with Cloud Application Services A bit of Configuration Register the Metro apps for Windows Live Application Management From the current app manifest of your metro app Publish tab, copy the Package Display Name and the Publisher From: https://manage.dev.live.com/Build/ Package name: <-- we need to change this Client secret: keep this Package Security Identifier (SID): keep this Verify the app here: https://manage.dev.live.com/Applications/Index - so this step is done "If you wish to send push notifications in your application, provide your Package Security Identifier (SID) and client secret to WNS." Provide Package SID & Client Secret to WNS http://msdn.microsoft.com/en-us/library/windows/apps/hh465407.aspx - How to authenticate with WNS https://appdev.microsoft.com/StorePortals/en-us/Account/Signup/PurchaseSubscription - register app with dashboard - need registration code or register a new account & pay $170 shekels http://msdn.microsoft.com/en-us/library/windows/apps/hh868184.aspx - Registering for a Windows Store developer account http://msdn.microsoft.com/en-us/library/windows/apps/hh868187.aspx - Picking a Microsoft account for the Windows Store The WNS Nuget Recipe The WNS Recipe is a nuget package that provides an API for authenticating against WNS, constructing payloads and posting notifications to WNS. After installing this package, a WnsRecipe assembly is added to project references. To send notifications using WNS, first register the application at the Windows Push Notifications & Live Connect portal to obtain Package Security Identifier (SID) and a secret key that your cloud service uses to authenticate with WNS. An application receives push notifications by requesting a notification channel from WNS, which returns a channel URI that the application then registers with a cloud service. In the cloud service, the WnsAccessTokenProvider authenticates with WNS by providing its credentials, the package SID and secret key, and receives in return an access token that the provider caches and can reuse for multiple notification requests. The cloud service constructs a notification request by filling out a template class that contains the information that will be sent with the notification, including text and image references.Using the channel URI of a registered client, the cloud service can then send a notification whenever it has an update for the user. var provider = new WnsAccessTokenProvider(clientId, clientSecret); var notification = new ToastNotification(provider) {     ToastType = ToastType.ToastText02,     Text = new List<string> { "blah"} }; notification.Send(channelUri); the WNS Recipe is instrumented to write trace information via a trace listener – configuratively or programmatically from Application_Start(): WnsDiagnostics.Enable(); WnsDiagnostics.TraceSource.Listeners.Add(new DiagnosticMonitorTraceListener()); WnsDiagnostics.TraceSource.Switch.Level = SourceLevels.Verbose; The WAT PNWorker Sample The Azure server side contains a WebRole & a WorkerRole. The WebRole allows submission of new push notifications into an Azure Queue which the WorkerRole extracts and processes. Overview of Push Notification Worker Sample The toolkit includes a sample application based on the same solution structure as the one created by theWindows 8 Cloud Application Services project template. The sample demonstrates how to off-load the job of sending Windows Push Notifications using a Windows Azure worker role. You can find the source code in theSamples\PNWorker folder. This folder contains a full version of the sample application showing how to use Windows Push Notifications using ASP.NET Membership as the authentication mechanism. The sample contains two different solution files: WATWindows.Azure.sln: This solution must be opened with Visual Studio 2010 and contains the projects related to the Windows Azure web and worker roles. WATWindows.Client.sln: This solution must be opened with Visual Studio 11 and contains the Windows Metro style application project. Only Visual Studio 2010 supports Windows Azure cloud projects so you currently need to use this edition to launch the server application. This will change in a future release of the Windows Azure tools when support for Visual Studio 11 is enabled. Important: Setting up the PNWorker Sample Before running the PNWorker sample, you need to register the application and configure it: 1. Register the app: To register your application, go to the Windows Live Application Management site for Metro style apps at https://manage.dev.live.com/build and sign in with your Windows Live ID. In the Windows Push Notifications & Live Connect page, enter the following information. Package Display Name PNWorker.Sample Publisher CN=127.0.0.1, O=TESTING ONLY, OU=Windows Azure DevFabric 2. 3. Once you register the application, make a note of the values shown in the portal for Client Secret,Package Name and Package SID. 4. Configure the app - double-click the SetupSample.cmd file located inside the Samples\PNWorker folder to launch a tool that will guide you through the process of configuring the sample. setup runs a PowerShell script that requires running with administration privileges to allow the scripts to execute in your machine. When prompted, enter the Client Secret, Package Name, and Package Security Identifier you obtained previously and wait until the tool finishes configuring your sample. Running the PNWorker Sample To run this sample, you must run both the client and the server application projects. 1. Open Visual Studio 2010 as an administrator. Open the WATWindows.Azure.sln solution. Set the start-up project of the solution as the cloud project. Run the app in the dev fabric to test. 2. Open Visual Studio 11 and open the WATWindows.Client.sln solution. Run the Metro client application. In the client application, click Reopen channel and send to server. à the application opens the channel and registers it with the cloud application, & the Output area shows the channel URI. 3. Refresh the WebRole's Push Notifications page to see the UI list the newly registered client. 4. Send notifications to the client application by clicking the Send Notification button.

With WNS, tier integration is so automated that you don’t even have to leverage a HTTP push API such as SignalR. This is a pretty powerful development paradigm, and has changed the way I look at Windows 8 for RAD business apps. When I originally looked at Win8 and the WinRT API, my first opinion on Win8 dev was as follows – GOOD:WinRT, WRL, C++/CX, WinJS, XAML (& ease of Direct3D integration); BAD: low projected market penetration,.NET lobotomized (Only 8% of .NET 4.5 classes can be used in Win8 non-desktop apps - http://bit.ly/HRuJr7); UGLY:Metro pascal tiles! Perhaps my 80s teenage years gave me a punk reactionary sense of revulsion towards the Partridge Family 70s style that Metro UX seems to have appropriated: On second thought though, it simplifies UI dev to a single paradigm (although UX guys will need to change career) – you will not find an easier app dev environment. Speculation: If LightSwitch is going to support HTML5 client app generation, then its a safe guess to say that vnext will support Win8 Metro XAML - a much easier port from Silverlight XAML. Given the VS2012 LightSwitch integration as a thumbs up from the powers that be at MS, and given that Win8 C#/XAML Metro apps tend towards a streamlined 'golden straight-jacket' cookie cutter app dev style with an Azure back-end supporting Win8 push notifications... --> its easy to extrapolate than LightSwitch vnext could well be the Win8 Metro XAML to Azure RAD tool of choice! The hook is already there - :) Why else have the space next to the HTML Client box? This high level of application development abstraction will facilitate rapid app cookie-cutter architecture-infrastructure frameworks for wrapping any app. This will allow me to avoid too much XAML code-monkeying around & focus on my area of interest: Technical Computing.

  • 12.10: login screen never goes blank

    - by Marciano Siniscalchi
    I have installed the 12.10 beta (with all updates) on my iMac Early 2008. One annoying problem I'm having is that, when I log out of my account and go back to the login screen (lightdm, per default), the screen stays on: it never goes blank. This is not good for my display I guess! The screensaver (set to just a blank screen) works just fine when I'm logged in. The problem only appears at the login screen. Any ideas?

  • Tabbed terminal that connects to a GNU Screen session?

    - by screenuser
    I use the session feature of screen extensively. For example, I'll start a screen session for "project1" as "screen -S project1", and then when I need to reconnect I use "screen -d -r project1". This makes it easy to manage multiple projects, each with their own set of shell sessions. What I would love to do now is that when running on Windows and Linux, to be able to use a tabbed terminal program (such as gnome-terminal) to connect to a screen session and have all of the screen windows split out to separate tabs. This way I get all the usual power of screen, but with the convenience of a richer GUI experience. Is there any such terminal program available on Windows and/or Linux?

  • Laptop screen blank after login when external monitor is not connected

    - by Ramon Suarez
    Ubuntu does not switch back automatically to only monitor present when booting after disconnecting external monitor. Here's a video showing what happens. I get to the login window and everything looks ok, then I type my password, the desktop image shows up and... everything goes blank. It does not happen when I just login as a guest. When possible I work with my laptop connected to an external screen via the VGA port. The problem comes when I boot the computer without that secondary screen connected: The login screen comes out ok. After login the screen goes black, but I can hear the login sound. If I hit ctr + alt + backwards-delete and login again sometimes it is fixed, but not all. If I log in as a different user everything is OK. Then I log in as my user and sometimes it works. To have a screen I have to plug a monitor. Although I have turned on the laptop display with that monitor on, if I reboot it goes blank again after login, even if I turn off the external monitor before turning off the computer. I've managed to get my screen back with my username after going into recovery mode, but only sometimes. Failsafe would not load after second screen asking me what I wanted to do (no mouse to click nor keyboard working). My computer is a LDLC Aurore BB1-i5 -8 -S1. Which is the configuration file that keeps the information about the monitors using Displays under lightgdm and where is it? I guess if I could edit it I may have a chance :) One of the things I tried following a solution in another post was removing my monitors.xml file, but it does not work and I don't know how to create a good one that I could use now. When doing DISPLAY=:0 xrandrI get: Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) This is the full dmesg after activating sudo xdiagnoseas Bryce sugested. (If you tell me the relevant parts I will paste them here) When conecting the external monitor, only the external will work, although I can see using Displays that the computer thinks that both are working. I've asked the question in Launchpad but have it keeps on expiring without any feedback. In my opinion Ubuntu should be able to detect automatically that there is no external monitor present and switch to the laptop monitor. There's a similar question here, but it does not apply to my case External monitor set as primary even when disconnected from laptop Update: For clarification, the problem happens only with my user and once I log in. I even get to see the screensaver for about a second, and then it goes blank. Tried Bryce's example (see his answer below), but it did not work. This is the info I get from tty1 with Display=:0 xrandr: – Ramon Suarez Jul 9 at 16:36 Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis)

  • Going Metro

    - by Tony Davis
    When it was announced, I confess was somewhat surprised by the striking new "Metro" User Interface for Windows 8, based on Swiss typography, Bauhaus design, tiles, touches and gestures, and the new Windows Runtime (WinRT) API on which Metro apps were to be built. It all seemed to have come out of nowhere, like field mushrooms in the night and seemed quite out-of-character for a company like Microsoft, which has hung on determinedly for over twenty years to its quaint Windowing system. Many were initially puzzled by the lack of support for plug-ins in the "Metro" version of IE10, which ships with Win8, and the apparent demise of Silverlight, Microsoft's previous 'radical new framework'. Win8 signals the end of the road for Silverlight apps in the browser, but then its importance here has been waning for some time, anyway, now that HTML5 has usurped its most compelling use case, streaming video. As Shawn Wildermuth and others have noted, if you're doing enterprise, desktop development with Silverlight then nothing much changes immediately, though it seems clear that ultimately Silverlight will die off in favor of a single WPF/XAML framework that supports those technologies that were pioneered on the phones and tablets. There is a mystery here. Is Silverlight dead, or merely repurposed? The more you look at Metro, the more it seems to resemble Silverlight. A lot of the philosophies underpinning Silverlight applications, such as the fundamentally asynchronous nature of the design, have moved wholesale into Metro, along with most the Microsoft Silverlight dev team. As Simon Cooper points out, "Silverlight developers, already used to all the principles of sandboxing and separation, will have a much easier time writing Metro apps than desktop developers". Metro certainly has given the framework formerly known as Silverlight a new purpose. It has enabled Microsoft to bestow on Windows 8 a new "duality", as both a traditional desktop OS supporting 'legacy' Windows applications, and an OS that supports a new breed of application that can share functionality such as search, that understands, and can react to, the full range of gestures and screen-sizes, and has location-awareness. It's clear that Win8 is developed in the knowledge that the 'desktop computer' will soon be a very large, tilted, touch-screen monitor. Windows owes its new-found versatility to the lessons learned from Windows Phone, but it's developed for the big screen, and with full support for familiar .NET desktop apps as well as the new Metro apps. But the old mouse-driven Windows applications will soon look very passé, just as MSDOS character-mode applications did in the nineties. Cheers, Tony.

  • bash screen title usage (screen -t "something")

    - by atrioom
    I was working with screen lately and wanted to use the -t option for it. What's the point of the-t option if the title of the screen does not show anywhere like when using -list or within the screen when it's attached? There is a command CTRL-A double-quote(") to see all active screens, and then it shows the title, but that does not really do the job, because I have to have the screen attached already. I want to read out the title BEFORE attaching any screens, to attach the right one in the first place. Is there a method to use -t in a convenient way? Edit: There is one method: "ctrl-a "" and then "ctrl-a {numberofscreen}". I guess that's the best way to use the screen titles?

  • How to totaly remove blank screen screensaver?

    - by Xamidovic
    I have no screensaver installed but when I watch movies after a while blank screen comes and I have to get up every time and move mouse to continue watching the movie. It really pisses me off. I found this command "gsettings set org.gnome.desktop.screensaver idle-activation-enabled false" which allegedly disables blank screen... I put that command in once, and blank screen keeps doing its crap. I did it again, blank screen still works on its own and would not stop. Did it trice, and nothing. Please someone help me with this, I'm freaking out when trying to watch a decent movie. I'd have to mention that I once had "xscreensaver" installed but I removed it after awhile. Don't know if it has something to do with blank screen still work, maybe some else would know. PLEASE HELP !

  • Curiosity on any Smartphones that Run on Android 2.3.3 with Different Screen Reoslution

    - by David Dimalanta
    I have a question regarding about any smartphones that run only in Android 2.3.3. Is the size of screen or the screen resolution is always HVGA or does it have capable of running this OS (Android 2.3.3) on big screen size (4" to 5") at about 720x1280? I'm thinking of the game's compatibility depending on the version of the Android OS and the screen resolution, which affects the change of coordinates especially for assigning touch buttons and drag-n-drop at exact location, before I'm gonna decide to make one. My program works on the Android 4 ICS and Jellybean, however, will that work on Android 2.3.3 in spite of precise touch coordinate or just dependent on the screen resolution (regardless how large it is) as the X and Y coordinate? And take note, I'm using Eclipse IDE for Java developers.

  • Good practices in screen states management?

    - by DevilWithin
    I wonder what are the best ways to organize different screens in a game? I am thinking of it like this: Inheriting a base State class, and overriding update and render methods, to handle the current screen. Then, under certain events a StateManager is able to activate another Screen State, and the game screen changes as only the current State is rendered. On the activation of a new screen, effects like fading could be added, and also the same goes for its deactivation. This way a flow of screen could be made. By saying when A ends, B starts, allowing for complex animations etc. Toughts?

  • How do I fix this half screen problem?

    - by link1275
    I just installed 12.04, and my entire screen is being displayed entirely on the top half of my screen. The bottom half is always black or some technical garbage from the boot up. To interact with the bottom half of the screen I have to move the mouse over the screen to pull part of the bottom half of the screen on top and vice-versa. Does anyone know how to fix this? Also my computer told me, at startup, to go to here: http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware.

  • Ubuntu not shutting down ( going to black screen ) 12.04

    - by Orrin Fox
    I am currently using a USB persistent install of ubuntu. its a simple 4GB drive with a 2.8GB partition ( casper-rw storage partition ). I setup an administrator account and set it to login automatically. I also removed ubiquity to simply use this as a go anywhere install. Heres my issue. Im logged in as my account, and I click the top right gear and select "shut down". Text pops up showing its quitting processes.. etc. and then goes to the plymouth animation. But... The screen goes black, and then it goes to the login screen. Now when im at the login screen i go into terminal ( alt+F2 ) and dont you know, im logged in as Ubuntu. so then I try the following: ubuntu@ubuntu:~$ sudo shutdown now It goes to the plymouth screen again as if its shutting down, AND the screen goes black once again but the computer has not turned off, as in the usb is still flashing the light, the fans are still on, the only thing off is the screen. Is this a bug? If not maybe i did something wrong? Perhaps its that I made an account but... if there is a work around for this please let me know. Thanks again, Fox

  • Blank Screen ... No Bios Loading Screen Either

    - by SwissStar
    I don't even know how long it's been but I had given up. until now. My screen does not come on AT ALL, not even and the Bios loading screen. I have to connect it to my TV in order to see. But there's one thing that has always started it back up, and that is by running a hard ware Diagnostics * Provided by DELL* . It is definitely has something to do with Ubuntu. I know that for sure, because I remember running an update and BAM . That was it for the screen. How could I restore my screen back to Life ? I have a Nvidia Graphics Card.

  • Live CD has black screen HP DV6

    - by Shaun Killingbeck
    Attempting to install/try ubuntu (11.10, 12.04) on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0, and also now i915.modeset=1 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. Update: Tried the ?orkarounds on https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen - set gfxpayload=text changed nothing, removing splash did nothing and setting vesafb.nonsense=1 did nothing either. I'd like to be able to collect some log information somehow, but I can't get to a command line from the liveCD. tried using the latest 12.04 beta, same issue tried nomodeset without splash or quiet. get the following (tail of) output before it freezes on that screen: * Starting configure network device security [OK] * Starting configure network device [OK] [ 25.720899] ieee80211 phy0: w1_ops_config: change monitor mode: false (implement) [ 25.720923] ieee80211 phy0: w1_ops_config: change power-save mode: false (implement) * Starting restore sound card(s') mixer state(s) [fail] [ 25.721849] ieee80211 phy0: w1_ops_bss_info_changed: qos enabled: false (implement) * Stopping save kernel messages [OK] * Starting bluetooth [OK] * PulseAudio configured for per-user sessions saned disabled; edit /etc/default/saned [ 25.988016] hci_cmd_timer: hci0 command tx timeout [ 26.207225] bad LUN (0:1) [ 26.223735] bad target number (1:0) [ 26.252111] bad target number (2:0) [ 26.272170] bad target number (3:0) [ 26.300154] bad target number (4:0) [ 26.328162] bad target number (5:0) [ 26.344180] bad target number (6:0) [ 26.368142] bad target number (7:0) * Checking battery state...

  • ssh-agent key timeout with screen or tmux on bastion host

    - by Jericon
    Normally I have ssh-agent running, I ssh to my bastion host then open a tmux session and connect to other boxes through that. Key forwarding works for any sessions that I open from that point forward. If I resume my tmux session after closing terminal, sleeping my laptop, whatever, my key forwarding on my bastion sessions still work, as does forwarding on any new sessions. Existing ones don't work, though. I have a little thing in my bashrc that keeps key forwarding working when I resume tmux, but I am having trouble figuring out how to get it to keep working for sessions open within tmux. For example, I have bastion01, dbhost01, dbhost02, webhost01, and webhost02. If I open a connection to bastion01, start tmux there, and then connect to dbhost01 and webhost01 forwarding works. If I close that connection, reconnect and attach my existing tmux session, then add connections to dbhost02 and webhost02, key forwarding works on the 02 boxes, but does not on the 01. Please help!

  • Flashing window in gnu screen

    - by gotts
    I really like gnu screen but there is a problem in my environment when I use it. Examle: username@domain:/var/www$ l Display all 130 possibilities? (y or n) when you click [Tab] to perform autocompletion there is a screen flashing for a very short period of time(looks like white screen but I can see it for a very-very short time). There isn't any problems with that when I execute the same action in normal/non-screen environment. This is what my .screenrc looks like: attrcolor b ".I" termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' defbce "on" term screen-256color-bce

  • Can I use GNU Screen completely transparently/automatically?

    - by dreeves
    Screen is amazing, of course, but I don't want to have to think about it. I often ssh to a machine, start doing a bunch of stuff, and then think "gosh, I wish I had thought to start a screen session before doing all that so I could reconnect to this from home later". I'd like to have screen automatically started whenever I log in to a machine. And when I get disconnected, I want to be able to immediately and simply reconnect without fussing with "screen -ls" and "screen -dr". I have a script that implements one solution to this problem which I'll post as an answer. I'm interested to see other approaches.

  • GNU Screen: one window per screen or one screen with multiple windows?

    - by yalestar
    I've inherited a few sys admin tasks recently and am trying to wrap my head around using screen. The way the previous guy left it, there are four screen sessions running, some of which have two or three windows running within. It doesn't appear that he was using any particular convention, so I ask you: Is it better to have each process in its own screen session, or better to group similar processes into a single screen? Or something different entirely?

  • shutdown windows 8 from metro app

    - by MindFreak
    I'm doing a metro app for Windows 8. And as part of its functionality, I need to initiate shutdown of Winodws 8 from the Metro App. Here are the questions: 1) Firstly, I researched a lot on this topic and I found out that System.Diagnostics.Process is not available for Metro App. So, is there a another way around? 2) Even if I can't directly shutdown, is there a way to trigger it from the Metro App? I would prefer a solution in C#. Thanks.

  • Precise Touch Screen Dragging Issue: Trouble Aligning with the Finger due to Different Screen Resolution

    - by David Dimalanta
    Please, I need your help. I'm trying to make a game that will drag-n-drop a sprite/image while my finger follows precisely with the image without being offset. When I'm trying on a 900x1280 (in X [900] and Y [1280]) screen resolution of the Google Nexus 7 tablet, it follows precisely. However, if I try testing on a phone smaller than 900x1280, my finger and the image won't aligned properly and correctly except it still dragging. This is the code I used for making a sprite dragging with my finger under touchDragged(): x = ((screenX + Gdx.input.getX())/2) - (fruit.width/2); y = ((camera_2.viewportHeight * multiplier) - ((screenY + Gdx.input.getY())/2) - (fruit.width/2)); This code above will make the finger and the image/sprite stays together in place while dragging but only works on 900x1280. You'll be wondering there's camera_2.viewportHeight in my code. Here are for two reasons: to prevent inverted drag (e.g. when you swipe with your finger downwards, the sprite moves upward instead) and baseline for reading coordinate...I think. Now when I'm adding another orthographic camera named camera_1 and changing its setting, I recently used it for adjusting the falling object by meter per pixel. Also, it seems effective independently for smartphones that has smaller resolution and this is what I used here: show() camera_1 = new OrthographicCamera(); camera_1.viewportHeight = 280; // --> I set it to a smaller view port height so that the object would fall faster, decreasing the chance of drag force. camera_1.viewportWidth = 196; // --> Make it proportion to the original screen view size as possible. camera_1.position.set(camera_1.viewportWidth * 0.5f, camera_1.viewportHeight * 0.5f, 0f); camera_1.update(); touchDragged() x = ((screenX + (camera_1.viewportWidth/Gdx.input.getX()))/2) - (fruit.width/2); y = ((camera_1.viewportHeight * multiplier) - ((screenY + (camera_1.viewportHeight/Gdx.input.getY()))/2) - (fruit.width/2)); But the result instead of just following the image/sprite closely to my finger, it still has a space/gap between the sprite/image and the finger. It is possibly dependent on coordinates based on the screen resolution. I'm trying to drag the blueberry sprite with my finger. My expectation did not met since I want my finger and the sprite/image (blueberry) to stay close together while dragging until I release it. Here's what it looks like: I got to figure it out how to make independent on all screen sizes by just following the image/sprite closely to my finger while dragging even on most different screen sizes instead.
