  • Help, broken Gsettings

    - by Rene
    I was trying to disable the global menu as per http://ubuntuhandbook.org/index.php/2013/07/disable-global-menu-on-ubuntu-13-10-saucy/#comment-8612, but while it didn't change anything, after running the autoremove command unity-tweak-tool broke. Obviously my first reaction was to re-install the removed package but it remains broken. TBH I don't know if it is even related or just a coincidence. When I start it from the launcher it just blinks and disappear. When I start it from terminal I get this error: $ gnome-tweak-tool WARNING : Shell not installed or running WARNING : Error detecting shell Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/gtweak/tweaks/tweak_shell_extensions.py", line 199, in __init__ raise Exception("Shell not running or DBus service not available") Exception: Shell not running or DBus service not available INFO : GSettings missing key org.gnome.nautilus.desktop (key computer-icon-visible) WARNING : Shell not running None INFO : GSettings missing key org.gnome.mutter (key workspaces-only-on-primary) Segmentation fault (core dumped) I had a look with dconf-editor if I could just add the missing key, but apparently keys aren't meant to be added "by hand". So how can I fix this? I'd rather prefer not having to reinstall everything. Which package is broken, can I just reinstall that? EDIT: I found by being root gnome-tweak-tool no longer crashed so possibly a permission issue somewhere. I don't know that I changed any permissions. Another related problem, actually the reason I noticed the problem at all, is that unity-tweak-tool seem no longer to want to save the values edited. I normally just have the Unity launcher on the primary display but wanted to check what it was like having it on both. I didn't like it so I went into unity-tweak-tool to set it back - but regardless how many time I tick "only primary display" it never changes anything. What does the Unity-tweak-tool actually change and can I do this directly somehow?

  • Software Architecture and Design vs Psychology of HCI class

    - by Joey Green
    I have two classes to choose from and I'm wanting to get an opinion from the more experienced game devs which might be better for someone who wants to be an indie game dev. The first is a Software Architecture and Design course and the second is a course titled Psychology of HCI. I've previously have taken a Software Design course that was focused only on design patterns. I've also taken an Introduction to HCI course. Software Architecture and Design Description Topics include software architectures, methodologies, model representations, component-based design ,patterns,frameworks, CASE-based desgins, and case studies. Psychology of HCI Description Exploration of psychological factors that interact with computer interface usablilty. Interface design techniques and usability evaluation methods are emphasized. I know I would find both interesting, but my concern is really which one might be easier to pick up on my own. I know HCI is relevant to game dev, but am un-sure if the topics in the Software Architecture class would be more for big software projects that go beyond the scope of games. Also, I'm not able to take both because the overlap.

  • Is it possible to install Canon EOS T3 Camera Drivers on Windows 7 Embedded

    - by Ryan Johnson
    I have a computer running Windows 7 Embedded. It's an embedded system that will be used in a industrial setting. It needs to be connected to a Canon EOS camera and download pictures from the camera. Other versions of windows come with the Canon drivers so Canon does not provide them as a download on their website. In the past, I had a similar issue with the "N" version of Microsoft Windows Starter and had to download the "Microsoft Media Feature Pack" which then installed the drivers. I attempted to install that on this device, but understandably it complains that its not applicable for this version of windows. So, is there there a feature pack or some other sort of download available that will install the camera drivers? Alternatively, is there some place to get the drivers and manually install them. Thanks in Advance, Ryan

  • Ubuntu with Netatalk and Samba TimeMachine can't connect

    - by Philip
    I installed netatalk on my Ubuntu Server a few weeks ago and configured it so that I could use Timemachine from my mac to backup on a server instead of a external hard drive. It worked really good until yesterday when I installed Samba to be able to share certain folders on my server to my mac. Now I receive an error msg: There are no shares available or you are not allowed to access them on the server. Please contact your system administrator to resolve the problem. From what I understand is that the problem is on the server and not on my mac. I have tried to restart the computer and without adding any of the folders Samba is sharing adding the timemachine "afp://...@...". Is there a problem running them both at the same time, do I need to configure samba so that it doesn't reject afp? I'm pretty new at this...

  • Windows 7 Upgrade from an OEM disc

    - by user1026361
    I recently bought a new laptop with Windows 7 Home Premium and a Windows 7 Pro Upgrade key. It also comes with a cavalcade of bloatware. I would like to start with a fresh install of Windows. I understand that I can upgrade to W7Pro using the option in the Home Premium Start menu. However, I also own a Windows 7 Pro OEM installation disc from another computer. Can I use this Windows 7 Pro OEM disc to install Windows, and when it asks me for my key, provide the upgrade key purchased? Or am i required to install Home Premium first and then apply my upgrade key?

  • Cannot activate windows 7

    - by Charlie
    I can't activate Windows 7, I get an error saying DNS name does not exist. Is something configured incorrectly somewhere? PS: I need the answer within 13 days ;) UPDATE: I had upgraded from my company's Windows Vista build, and when I connect to the company VPN and activate I get a different error: The Software Licensing Service reported that the computer could not be activated.

  • NetApp erroring with: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT

    - by Sobrique
    Since a sitewide upgrade to Windows 7 on desktop, I've started having a problem with virus checking. Specifically - when doing a rename operation on a (filer hosted) CIFS share. The virus checker seems to be triggering a set of messages on the filer: [filerB: auth.trace.authenticateUser.loginTraceIP:info]: AUTH: Login attempt by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20 (server-wk8-r2). [filerB: auth.dc.trace.DCConnection.statusMsg:info]: AUTH: TraceDC- attempting authentication with domain controller \\MYDC. [filerB: auth.trace.authenticateUser.loginRejected:info]: AUTH: Login attempt by user rejected by the domain controller with error 0xc0000199: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT. [filerB: auth.trace.authenticateUser.loginTraceMsg:info]: AUTH: Delaying the response by 5 seconds due to continuous failed login attempts by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20. This seems to specifically trigger on a rename so what we think is going on is the virus checker is seeing a 'new' file, and trying to do an on-access scan. The virus checker - previously running as LocalSystem and thus sending null as it's authentication request is now looking rather like a DOS attack, and causing the filer to temporarily black list. This 5s lock out each 'access attempt' is a minor nuisance most of the time, and really quite significant for some operations - e.g. large file transfers, where every file takes 5s Having done some digging, this seems to be related to NLTM authentication: Symptoms Error message: System error 1808 has occurred. The account used is a computer account. Use your global user account or local user account to access this server. A packet trace of the failure will show the error as: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT (0xC0000199) Cause Microsoft has changed the functionality of how a Local System account identifies itself during NTLM authentication. This only impacts NTLM authentication. It does not impact Kerberos Authentication. Solution On the host, please set the following group policy entry and reboot the host. Network Security: Allow Local System to use computer identity for NTLM: Disabled Defining this group policy makes Windows Server 2008 R2 and Windows 7 function like Windows Server 2008 SP1. So we've now got a couple of workaround which aren't particularly nice - one is to change this security option. One is to disable virus checking, or otherwise exempt part of the infrastructure. And here's where I come to my request for assistance from ServerFault - what is the best way forwards? I lack Windows experience to be sure of what I'm seeing. I'm not entirely sure why NTLM is part of this picture in the first place - I thought we were using Kerberos authentication. I'm not sure how to start diagnosing or troubleshooting this. (We are going cross domain - workstation machine accounts are in a separate AD and DNS domain to my filer. Normal user authentication works fine however.) And failing that, can anyone suggest other lines of enquiry? I'd like to avoid a site wide security option change, or if I do go that way I'll need to be able to supply detailed reasoning. Likewise - disabling virus checking works as a short term workaround, and applying exclusions may help... but I'd rather not, and don't think that solves the underlying problem. EDIT: Filers in AD ldap have SPNs for: nfs/host.fully.qualified.domain nfs/host HOST/host.fully.qualified.domain HOST/host (Sorry, have to obfuscate those). Could it be that without a 'cifs/host.fully.qualified.domain' it's not going to work? (or some other SPN? ) Edit: As part of the searching I've been doing I've found: http://itwanderer.wordpress.com/2011/04/14/tread-lightly-kerberos-encryption-types/ Which suggests that several encryption types were disabled by default in Win7/2008R2. This might be pertinent, as we've definitely had a similar problem with Keberized NFSv4. There is a hidden option which may help some future Keberos users: options nfs.rpcsec.trace on (This hasn't given me anything yet though, so may just be NFS specific). Edit: Further digging has me tracking it back to cross domain authentication. It looks like my Windows 7 workstation (in one domain) is not getting Kerberos tickets for the other domain, in which my NetApp filer is CIFS joined. I've done this separately against a standalone server (Win2003 and Win2008) and didn't get Kerberos tickets for those either. Which means I think Kerberos might be broken, but I've no idea how to troubleshoot further. Edit: A further update: It looks like this may be down Kerberos tickets not being issued cross domain. This then triggers NTLM fallback, which then runs into this problem (since Windows 7). First port of call will be to investigate the Kerberos side of things, but in neither case do we have anything pointing at the Filer being the root cause. As such - as the storage engineer - it's out of my hands. However, if anyone can point me in the direction of troubleshooting Kerberos spanning two Windows AD domains (Kerberos Realms) then that would be appreciated. Options we're going to be considering for resolution: Amend policy option on all workstations via GPO (as above). Talking to AV vendor about the rename triggering scanning. Talking to AV vendor regarding running AV as service account. investigating Kerberos authentication (why it's not working, whether it should be).

  • DSL PPPoE connection not working?

    - by Mussnoon
    I use a wired PPPoE connection to connect to the Internet. What I need to do on Windows to connect to it is put in static IP address, gateway, subnet mask and DNS servers for my LAN card. Next I have to create a dialer for a PPPoE connection, put in my user name, the service name and the password, and "dial" this connection. And it works fine. On Ubuntu 10.04, however, I have tried setting things up in a similar fashion - put in all static addresses for the "automatic" wired connection, then put in user name, service name, password for a "DSL" connection. It worked for a while, then stopped. I have tried putting in all the details within the DSL configuration dialog, same thing happened - it worked for a while, then stopped. I have tried deleting the ethernet connection and only keeping the DSL one with all the numbers put in place, same thing happened - it worked for a while, then stopped. Each of the times, when it connected, it connected randomly, after trying a few times, and either stopped working within a few minutes, or after I had rebooted. I have deleted and remade the connection dozens of times - even with different names, but nothing seems to be working. I have also tried pppoeconf from the terminal, didn't work. I have checked /var/log/kern.log, but nothing changes in the file when I try to connect. I have also checked /sbin/route, but gedit can't even open it (says it can't figure the character encoding...). The "connection established" notification pops up from the top right corner, the same way as when the computer is actually connected to a network. Can anyone figure what's wrong and how it can be solved?

  • Why does Windows run CHKDSK on every boot?

    - by khris
    Every time I turn on my PC, I get the following message: Checking file system on E: The type of the file systen is NTFS. One of your disks need to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue. Windows will now check the disk. CHKDSK is verifying files (stage 1 of 3)... 0 percent completed I allow CHKDSK to to complete, but Windows does not load. This message appears every time I boot my computer. Could someone explain me why this message appears and what I should do to make it disappear?

  • Fullscreen Video stutters on second monitor laptop

    - by nobrandheroes
    Fullscreen video on my new 1080p monitor is choppy when it comes from my laptop. The same video plays when not full screen. This goes for all video(Flash/MKV, etc), regardless of video resolution. I have an ATI Mobility Radeon HD 4200 Series card in my Thinkpad Edge, Turion X2 2GHz. The computer plays 1080p fine. Things I've tried: Updating Drivers Switching cables Turning Hardware Acceleration Changing video players process priority Rebooting Turning of laptop screen Turning off unused processes Nothing Works. What is the likelyhood that my laptop cannot power a 1920x1280 display?

  • Dual-headed graphics card choice: DVI & VGA with 512MB _or_ DVI & DVI with 256MB

    - by TimH
    Which would you choose? Some more detail: I can choose between: A dual-headed card with both heads DVI but only 256MB of memory A dual-headed card with one VGA and one DVI, with 512MB of memory. Both monitors are 1600x1200 I'll be doing mostly business app development on the computer. No gameplay or advanced graphics work. It's running Win7 and is a quad-core i5. I'm thinking of going with 256MB one, just so both displays are DVI and I don't have to shift between sharp & blurry when I look from one screen to the other. But I'm not sure if the additional RAM would be a huge boon for some reason (Win7 GPU acceleration, for example? But with a quad-core, who cares?).

  • Authenticating Linux users against AD without Likewise Open

    - by Graeme Donaldson
    Has anyone got their Linux systems authenticating against Active Directory without using Likewise Open? We are close to implementing Likewise Open, but first we need to rename roughly 70 of 110 Linux servers so that their hostnames are not longer than 15 characters. This is required because Likewise Open actually joins the Linux computer to the domain, and it fails to do so if the hostname is too long due to some legacy NetBIOS naming limitation. Is there a way to authenticate via AD, using only LDAP perhaps? What are the advantages/disadvantages over doing it like that vs just using Likewise?

  • Creating an interactive "movie" from a Microsoft PowerPoint 2003 presentation (.ppt file) containing animation

    - by Andrew
    I have created a Microsoft PowerPoint 2003 presentation (a .ppt file) on Windows XP that contains a lot of animation, using PowerPoint's Custom Animation tools. I would like to share this presentation -- animations and all -- with a colleague who has a Mac computer and does not have PowerPoint or Keynote. Is it possible to make a "movie" from my .ppt file that contains a lot of animation? I recall that another colleague once made me a QuickTime "movie" from a PowerPoint file, I think (although I do not remember whether he made it using Windows or Mac). On this "movie," clicking advanced the animation/slide, just as clicking would do in an actual PowerPoint presentation. In that sense, it was not really strictly a movie, since I could interact with it by clicking. Do you know how to make such an interactive "movie" from a PowerPoint 2003 presentation (a .ppt file)? Thank you for your time!

  • the right way to do deployment with capistrano

    - by com
    I look for good practices for deploying with capistrano. I would like to start out with a short description how I used to do deployment. capistrano is installed locally on a developer's computer. I deploy thought gateway with capistrano option :gateway. Firstly, I thought that with :gateway option I need to have ssh connection only to gateway host, but it turns out that I need ssh connection (public key) to all hosts where I want to deploy to. I would like to find a convenient and secure way to deploy application. For example, in case when new developer starts working, is much more convinient to put his *public_key* only on gateway server and not on all applications servers. On the other hand I don't want him to have any connection to servers in particular ssh to gateway, just because he is developer, he needs to do only deployments. If you are aware of good practices for deploying with capistrano, please, let us know.

  • Windows 7 - Windows get autoselected

    - by DjRikyx
    I have a really annoying problem in Windows 7. I just updated Windows vista to Windows 7 32bit The problem is that every second the top windows is being selected. To explain better what happens: I open task manager and leave it there, then i select a icon on desktop, after 1 second, the icon is deselected and Task Manager windows is selected. Also i see windows borders blinking, every second. This is Annoying, because every time i do a right click or selecting a menu in any application, every second the menu get closed... I do not know what is doing this, i searched in task manager for some 'bad' application running, but seems ok, tried closing all programs but it's still there. If i restart the computer first i don't get that problem, but after a while it start.. I noticed that When using Visual Studio Express 2012, but i don't think is the problem, because also if i close VS the problem remains. Hope you can help me, i'm getting hungry!! It's annoying!

  • Windows 8 Restore Problems

    - by Joe
    I created a Windows 8 system image backup on a separate drive before I installed Linux, and during the Linux installation process I accidentally wiped out Windows. I now want to restore my Windows 8 backup that I have on the separate drive. I created a repair USB stick and I followed the directions according to this article. After selecting the image on the hard drive, I get this error: "To restore this computer, Windows needs to format the hard drive." I don't know what this means! The drive partitions are different now then they were when I backup up, so I don't know if that matters. I re-installed Windows and I can restore my files from this backup, but I don't think this covers the registry, etc. I want a full restore. Does anyone know how to fix this problem, or how to restore in a different way? Thanks!

  • Processor speeds on my machine don't live up to manufacturer hype

    - by atch
    Why am I not seeing the promised speed claims of processor manufacturers on my computer? Producers of processors claim that their product can perform so many thousands (or millions) of operations per second. And yet on my machine (4GB, 3500hz), the typical program (Word, Visual Studio etc.) takes at least 10 seconds to start. I've formatted my hard drive and ticked all the necessary boxes to optimize my machine and yet I'm not seeing the promised speeds. Say it takes Outlook ten seconds to load. How many millions of operations does it really go through in order to start up?

  • Unable to modify variables phpmyadmin via variables tab (Xampp)

    - by rookie coder
    I am quite new to phpmyadmin configuration. I had project where utf8 encoding is needed. What i'm trying to do is to change the variables text/char all into utf8. I changed, yes at that moment the values changed into values I wanted. But then when I terminate Xampp and reenters phpmyadmin page or even refreshing the page, all the values restored to default (original values). My phpmyadmin had default user as root and hadn't been set a password yet. There is also no logout button in phpmyadmin landing page. I had difficult time even to set the server connection collation (hangs indefinitely and never seems can be updated). phpmyadmin version:4.1.6 mysql:5.5.36 (latest version) I doubt this could be due to malformed installation, because same things happened in my other computer too (exactly the same versions). what could be wrong? thanks.

  • setting visual bell to flash in iTerm

    - by blackwing
    Hi, I am using iTerm on OSX (leopard) to ssh to a linux machine. I run screen on the dev machine to save my work between sessions. I am not a big fan of audio bell and I don't like screen's default 'Wuff Wuff' bell (or any other little message shown at bottom of the page). What I like though is to have flash (foreground and blackground colors swapped for a fraction of a second) as my visual bell. I used to use PuTTY and it is as simple as ticking a checkbox but I can't find such an option in iTerm. My question is how can I set my visual bell to flash? The ideal answer would work with iTerm on local computer, iTerm sshed to a linux server, and iTerm sshed to a linux server and ran screen.

  • Use external speakers with laptop hooked to separate monitor?

    - by lhan16
    I have a laptop with a set of external speakers hooked up to it on my computer desk. The speakers use the standard 3.5mm audio (headphones) jack. The speakers work fine, but I've recently added a separate monitor to my laptop via HDMI. With the monitor hooked up to my laptop and the speakers still hooked up to the laptop, sound will only come out of the built-in monitor speakers. When I look at my audio settings, there are three different "audio playback devices" showing up, but only the built-in monitor speakers make noise when I click "test" (and I hear nothing when I set any of the other devices as the default. Does anyone know how I can still use my external speakers when using a separate monitor with my laptop? I'm hoping there is a solution that doesn't require the laptop to be open or closed, because I use both scenarios. I came across this post, but it doesn't look like they had much luck.

  • Windows 8 scroll lag

    - by samayres1992
    Don't have an issue with the desktop experience, but when it comes to the apps, scrolling in some of them is impossible to use correctly. Very laggy and jumpy, which is surprising because my computer has relatively high specs, only a year old. Scrolling using the manual scroll bar has no lag whatsoever it's simply whenever I use my touchpad. Maybe it's a touchpad issue? or more likely windows 8 as it seems fine in desktop view for scrolling? Any ideas where the problem may lie? Thanks

    - by Richard DesLonde
    I have a simple setup. Server at home has local I.P. 192.168.1.3 IIS is running on the server and the website is up. Windows firewall on the server has an exception rule for port 80 TCP Router has static I.P. XX.XXX.XX.XXX Router is forwarding TCP port 80 to 192.168.1.3 My domain registrar is my DNS host and is pointing to the static I.P. XX.XXX.XX.XXX of the router Here's what I can and can't do. I can browse the website from within my home network either by I.P. or domain name. I can ping the domain and the I.P. from outside the network (from a computer at work). I can't browse the website either by domain name or by I.P. Wierd. Why I can't browse my website? Incidentally, I wasn't sure this question was appropriate for SO, but after finding a few others similar to it on SO, and no comments on those questions saying anything about it being innapropriate, I decided I would post this question. Let me know if this is not appropriate for SO, or is more appropriate for another of the SE websites. Thanks!
