  • Kubuntu login problem

    - by Balázs Mária Németh
    I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

  • USB3 boot device disappears post-grub

    - by JoBu1324
    I have an installation of Ubuntu 12.10 on a USB3 device, and it occasionally disappears during boot, dropping me into busybox. This is what I've been able to figure out so far: During a single boot, the following happened: At the grub2 menu, I typed c and dropped to the grub> prompt I typed ls -l and got a list of all the devices, including partitions and UUIDs - the USB3 partitions were available I escaped back to the boot select menu, selected the default item (ubuntu) and hit enter The screen went black for a second before turning into the purple Ubuntu boot screen with the dots (which usually indicates that the boot will fail. When all is well I don't get the black screen) The boot dropped into BusyBox v1.19.3 with the message `ALERT! /dev/disk/by-uuid/[uuid] does not exist blkid displays all of the partitions except those of the USB3 device, as does ls /dev/disk/by-uuid or any of the alternatives.

  • Creating a secure SQL server login - CHECK_EXPIRATION & CHECK_POLICY

    - by cabhilash
    In SQL Server you can create users using T-SQL or using the options provided by SQL Server Management Studio.   CREATE LOGIN sql_user WITH PASSWORD ='sql_user_password' MUST_CHANGE, DEFAULT_DATABASE = defDB, CHECK_EXPIRATION = ON, CHECK_POLICY = ONAs mentioned in the previous article (http://weblogs.asp.net/cabhilash/archive/2010/04/07/login-failed-for-user-sa-because-the-account-is-currently-locked-out-the-system-administrator-can-unlock-it.aspx) when CHECK_POLICY = ON user account follows the password rules provided in the system on which the SQL server is installed. When MUST_CHANGE keyword is used user is forced to change the password when he/she tries to login for the first time. CHECK_EXPIRATION and CHECK_POLICY are only enforced on Windows Server 2003 and later. If you want to turn off the password expiration enforcement or security policy enforcement, you can do by using the following statements. (But these wont work if you have created your login with MUST_CHANGE and user didn't change the default password) ALTER LOGIN sql_login WITH CHECK_EXPIRATION = OFF go ALTER LOGIN sql_login WITH CHECK_POLICY = OFF

  • CSS tags/media queries for chrome on iPhone [migrated]

    - by Mick79
    So Chrome is here for iOS.. Hoorah! However now due to the different screen layout (no footer toolbar) it messes with the ability to make a perfect layout for iphone web pages. I have a site for my company that resided perfectly inside an iphone screen, no scrolling required, it looked like an app. However now that chrome is here (and wildly popular) with its different screen layout, sites that were sized for iphone safari now look odd. Is there, or will there be, ways to isolate out chrome from safari and give them different CSS?

  • SDL Fullscreen and Gnome-panel

    - by Daniel
    On Ubuntu 10.10, the following SDL code cause Gnome-panel to cease updating its drawing, however it does still function (ie windows on the panel open where they should be, but you just have to know where they 'would be' on instinct/memory). Gnome-panel also leaves a "Untitled window" box in the panel. #include <SDL.h> int main() { SDL_Surface* Screen; if(SDL_Init(SDL_INIT_VIDEO) < 0) { return 1; } Screen = SDL_SetVideoMode(1280, 1024, 32, SDL_OPENGL | SDL_FULLSCREEN); SDL_FreeSurface(Screen); SDL_Quit(); return 0; } Is this something wrong with SDL? Something wrong with the code? Something wrong with Gnome-panel? Hopefully we can find out :) Note: SDL tag request? Seeing as it is quite popular when searched: http://askubuntu.com/search?q=SDL

  • Fails to boot after upgrade, stuck on winbind package

    - by Praetorian
    I started the upgrade from 11.04 to 11.10 last night. Once it got the installing packages part I left the computer unattended the rest of the night. When I checked it this morning the screen was blank and I couldn't get it to turn on. So I cycled power, and now I get the "Ubuntu 11.10" screen with the dots underneath, but then it gets to a blank screen and nothing more. I can get to the command line in recovery mode; here's a list of the things I've tried so far sudo apt-get update - the very first repository it checked sat at 0% for a long time (network cable is plugged in), so I cancelled with Ctrl+C Thought it might be a problem with display drivers, so I tried sudo apt-get install nvidia-glx - this gave me an error saying dpkg has been interrupted, manually run sudo dpkg --configure -a sudo dpkg --configure -a this installed / updated a bunch of stuff but got stuck at Starting Winbind daemon winbind Restarted and tried sudo dpkg --configure -a again but it gets stuck at same Windbind step What else can I do to fix this problem?

  • IKEA Lamps Hacked into Flexible Speaker Mounts

    - by Jason Fitzpatrick
    This simple hack combines the swing arms of two IKEA work lamps with a set of computer speakers for flexible and easily adjustable sound. IKEAHackers reader Bill Dwyer wanted an easy way to get the speakers off his desk but still be able to easily adjust them. By hacking apart two IKEA work lamps (he removed the light assembly and snipped the wires off) he was able to attach his computer speakers to the arms and, in the process, get them off the desk. The arms make it super simple to adjust the speakers exactly where he wants them, including towards other parts of his office/apartment.

  • draw fog of war using shaders

    - by lezebulon
    I am making a RTS game, and I'd like some advice on how to best render fog of wars, given what I'm already doing. You can imagine this game as being a classic RTS like Age of Empires 2, where the fog of war will basically be handled by a 2D array telling if a given "tile" is explored or not. The specific things to consider here are : 1) I'm only doing a few draw calls to draw the whole screen, using shaders, and I'm not drawing "tile by tile" in a 2D loop 2) The whole map is much bigger than the screen, and the screen can move every frame or so In that case, how could I draw the fog of war ? I have no issue maintaining on the CPU-side a 2D array giving the fog of war for each tile, but what would be the best way to actually display it dynamically ? thanks!

  • Ubuntu boots up maintenance shell?

    - by Andrew
    Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

  • Make Offscreen Sliding Content Without Hurting SEO [duplicate]

    - by etangins
    This question already has an answer here: How bad is it to use display: none in CSS? 5 answers On my website I have content which is positioned off the screen, and then slides in when you click a button. For example, when you click the news button, content slides in with news. It didn't occur to me that this might be labeled as a black hat SEO technique, because I have content positioned off the screen with CSS that links elsewhere on my site, and a search engine could very easily interpret that as me hiding content for SEO purposes by positioning it off screen. Obviously, my intention was not to hide content, but was to make a sort of UI/UX content slider where content slides into view when a button is clicked. How can I make something to this effect (where content slides in and out), that would not comprise SEO?

  • 5 Android Keyboard Replacements to Help You Type Faster

    - by Chris Hoffman
    Android allows developers to replace its keyboard with their own keyboard apps. This has led to experimentation and great new features, like the gesture-typing feature that’s made its way into Android’s official keyboard after proving itself in third-party keyboards. This sort of customization isn’t possible on Apple’s iOS or even Microsoft’s modern Windows environments. Installing a third-party keyboard is easy — install it from Google Play, launch it like another app, and it will explain how to enable it. Google Keyboard Google Keyboard is Android’s official keyboard, as seen on Google’s Nexus devices. However, there’s a good chance your Android smartphone or tablet comes with a keyboard designed by its manufacturer instead. You can install the Google Keyboard from Google Play, even if your device doesn’t come with it. This keyboard offers a wide variety of features, including a built-in gesture-typing feature, as popularized by Swype. It also offers prediction, including full next-word prediction based on your previous word, and includes voice recognition that works offline on modern versions of Android. Google’s keyboard may not offer the most accurate swiping feature or the best autocorrection, but it’s a great keyboard that feels like it belongs in Android. SwiftKey SwiftKey costs $4, although you can try it free for one month. In spite of its price, many people who rarely buy apps have been sold on SwiftKey. It offers amazing auto-correction and word-prediction features. Just mash away on your touch-screen keyboard, typing as fast as possible, and SwiftKey will notice your mistakes and type what you actually meant to type. SwiftKey also now has built-in support for gesture-typing via SwiftKey Flow, so you get a lot of flexibility. At $4, SwiftKey may seem a bit pricey, but give the month-long trial a try. A great keyboard makes all the typing you do everywhere on your phone better. SwiftKey is an amazing keyboard if you tap-to-type rather than swipe-to-type. Swype While other keyboards have copied Swype’s swipe-to-type feature, none have completely matched its accuracy. Swype has been designing a gesture-typing keyboard for longer than anyone else and its gesture feature still seems more accurate than its competitors’ gesture support. If you use gesture-typing all the time, you’ll probably want to use Swype. Swype can now be installed directly from Google Play without the old, tedious process of registering a beta account and sideloading the Swype app. Swype offers a month-long free trial and the full version is available for $1 afterwards. Minuum Minuum is a crowdfunded keyboard that is currently still in beta and only supports English. We include it here because it’s so interesting — it’s a great example of the kind of creativity and experimentation that happens when you allow developers to experiment with their own forms of keyboard. Minuum uses a tiny, minimum keyboard that frees up your screen space, so your touch-screen keyboard doesn’t hog your device’s screen. Rather than displaying a full keyboard on your screen, Minuum displays a single row of letters.  Each letter is small and may be difficult to hit, but that doesn’t matter — Minuum’s smart autocorrection algorithms interpret what you intended to type rather than typing the exact letters you press. Just swipe to the right to type a space and accept Minuum’s suggestion. At $4 for a beta version with no trial, Minuum may seem a bit pricy. But it’s a great example of the flexibility Android allows. If there’s a problem with this keyboard, it’s that it’s a bit late — in an age of 5″ smartphones with 1080p screens, full-size keyboards no longer feel as cramped. MessagEase MessagEase is another example of a new take on text input. Thankfully, this keyboard is available for free. MessagEase presents all letters in a nine-button grid. To type a common letter, you’d tap the button. To type an uncommon letter, you’d tap the button, hold down, and swipe in the appropriate direction. This gives you large buttons that can work well as touch targets, especially when typing with one hand. Like any other unique twist on a traditional keyboard, you’d have to give it a few minutes to get used to where the letters are and the new way it works. After giving it some practice, you may find this is a faster way to type on a touch-screen — especially with one hand, as the targets are so large. Google Play is full of replacement keyboards for Android phones and tablets. Keyboards are just another type of app that you can swap in. Leave a comment if you’ve found another great keyboard that you prefer using. Image Credit: Cheon Fong Liew on Flickr

  • Rendering Unity across multiple monitors

    - by N0xus
    At the moment I am trying to get unity to run across 2 monitors. I've done some research and know that this is, strictly, possible. There is a workaround where you basically have to fluff your window size in order to get unity to render across both monitors. What I've done is create a new custom screen resolution that takes in the width of both of my monitors, as seen in the following image, its the 3840 x 1080: How ever, when I go to run my unity game exe that size isn't available. All I get is the following: My custom size should be at the very bottom, but isn't. Is there something I haven't done, or missed, that will get unity to take in my custom screen size when it comes to running my game through its exe? Oddly enough, inside the unity editor, my custom screen size is picked up and I can have it set to that in my game window: Is there something that I have forgotten to do when I build and run the game from the file menu? Has someone ever beaten this issue before?

  • Unity Frustum Culling Issue

    - by N0xus
    I'm creating a game that utilizes off center projection. I've got my game set up in a CAVE being rendered in a cluster, over 8 PC's with 4 of these PC's being used for each eye (this creates a stereoscopic effect). To help with alignment in the CAVE I've implemented an off center projection class. This class simply tells the camera what its top left, bottom left & bottom right corners are. From here, it creates a new projection matrix showing the the player the left and right of their world. However, inside Unity's editor, the camera is still facing forwards and, as a result the culling inside Unity isn't rendering half of the image that appears on the left and right screens. Does anyone know of a way to to either turn off the culling in Unity, or find a way to fix the projection matrix issue?

  • Do I have to completely reinstall Ubuntu now that it won't boot?

    - by Dave M G
    I just tried installing software called Teamviewer. It said there was some kind of error with unresolved dependancies. Then I realized I was trying to install the 32 bit version, but I needed to install the 64 bit version. So I tried that, and I got an error saying that Ubuntu needed to do a partial upgrade. I thought that was weird, so I just wanted to abandon installing anything and get out of this. I exited all programs and rebooted, and now I can't get back into Ubuntu. After the GRUB screen I get a black screen and no login options. If I boot into recovery, I get the following screen: I booted up a live CD of 12.04 to see if that could help, but it seems the only option is to completely reinstall Ubuntu. Can I repair this in any way, or is my only option to make a fresh install?

  • Remove kubuntu-desktop from ubuntu 12.04 [closed]

    Possible Duplicate: How to completely remove desktop? So, I thought I managed to remove KDE completely, but apparently that did not work at all, because every KDE application is back, including the KDE splash screen. I ran sudo apt-get autoremove --purge kubuntu-desktop Then I ran sudo apt-get install --reinstall ubuntu-desktop Then I ran sudo sudo update-alternatives --config default.plymouth Then I rebooted and everything seemed to be the original ubuntu-desktop (without the kde splash screen and other KDE applications).

  • Wireless speed drops over time and doesn't get up if not reconnected

    - by Vili Lehto
    I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this?

  • Server-side Input

    - by Thomas
    Currently in my game, the client is nothing but a renderer. When input state is changed, the client sends a packet to the server and moves the player as if it were processing the input, but the server has the final say on the position. This generally works really well, except for one big problem: falling off edges. Basically, if a player is walking towards an edge, say a cliff, and stops right before going off the edge, sometimes a second later, he'll be teleported off of the edge. This is because the "I stopped pressing W" packet is sent after the server processes the information. Here's a lag diagram to help you understand what I mean: http://i.imgur.com/Prr8K.png I could just send a "W Pressed" packet each frame for the server to process, but that would seem to be a bandwidth-costly solution. Any help is appreciated!

  • Can't adjust brightness on a Sony Vaio T13 ultrabook

    - by Alex Barreira
    I recently installed Ubuntu 12.04 alongside Windows 7 in a Vaio T13 ultrabook. I cannot use the the Fn+F4 or Fn+F5 to change the brightness. The bubble appears indicating that brightness is being changed but with no visual impact on the screen. I've tried many solutions involving the manipulation of the /etc/default/grub file but none of them worked. Whenever I tried this manipulation the screen still didn't change, however the bubble stopped functioning properly. This is not a problem of the Fn shortcut. Even when I try to change it in the Brightness and Lock on System Settings, the bar does scroll but the screen remains unchanged. Does any one has a way around this mystery?
