• Dual Monitor/Xinerama not working; cannot even detect on-board graphic card

  - by Steven H

  I have Kubuntu 12.04 and two identical VGA monitors. One I plugged via DVI-VGA adapter into the DVI port of my discrete AMD Radeon HD 6670, the other into the VGA port of my on-board graphic card (Radeon HD 6410D). After installing Kubuntu I got a black screen, so I booted with nomodeset and installed AMD's catalyst drivers but only the monitor plugged into the discrete graphic card worked. Using lspci I saw that the on-board graphics was not listed. Then I found in the BIOS settings the options "Surround View" and "Onboard Dual Link DVI" both disabled. After enabling both, the on-board graphics card shows up in lspci but in amdcccle, it only shows as [Uknown display]Uknown adapter. When I try to enable xinerama, I get a black screen after rebooting on both monitors. I tried several options and hints from the web but nothing worked so far. I also reinstalled the AMD drivers several times. What should I do?

• audio not playing through headphones

  - by JItendra

  I am using DELL alienware m14x. I have installed ubuntu 14.04 on my laptop. The problem that I am facing is that the audio plays only through speakers all the time even I though i plugin my headphone. When I go to sound settings it is showing me headphones in the "play sound through" which means that my system is able to detect the headphones but just the audio doesn't play through the headphones, instead it still plays through speaker. Can anyone one help me to figure it out please ! Thanks and Regards, Jitendra

• (Xubuntu) no touchpad or mouse on Aspire One D270

  - by Sman789

  I installed Xubuntu 12.10 on an Aspire One D270 using a Live USB. Initially, the live USB wouldn't boot, but by running sudo apt-get dist-upgrade on it (on a different machine), I upgraded the kernel and it now works perfectly. However, after installing Xubuntu from the stick onto the D270, neither the touchpad nor an external mouse works. If I use the keyboard to navigate to the mouse settings, the 'device' setting is greyed out. I don't see why the mouse should work perfectly when running from the live USB but not once installed to the machine...? Thanks for any help.

• Updated 11.10 - now trackpad and wifi won't work. How can these be fixed?

  - by Aron Standley

  I reinstalled 11.10 on my Asus EEE 1005HA, and my mousepad hasn't been working since. I've tried the workarounds mentioned in this post: http://ubuntuforums.org/showthread.php?t=1867357 but, I get the message on the command line that says, "Synaptic isn't installed." When I go to the network settings to install Synaptic, I can't turn on wifi - no wireless options exist. How can I turn on wifi from the command line, on a new 11.10 install? Or, is there a way to turn on the trackpad and wifi from the install thumb drive? How can I move forward?

• Visual Studio 2010 Setup Projects and x64 Support

  - by Shawn Cicoria

  I was taking the Windows Azure CmdLets project and getting it into an MSI just to make it easier to deploy in a nice package.  I ran into problems with the Setup project not being able to properly establish the right registry settings for an x64 environment. Even though you set the target platform on the Setup project to x64 the InstallUtil.lib that get’s run is still x86.  In order to have it work property, you need to follow the steps identified here: http://msdn.microsoft.com/en-us/library/kz0ke5xt.aspx  The section “64-bit managed custom actions throw a System.BadImageFormatException exception” covers the steps you need to follow, using the Orca MSI editor to replace the InstallUtilLib.dll from the one that the Setup Project embeds (x86) to a x64 version. Now, works like a charm… Resultant installer here: http://cicoria.com/Downloads/AzureManagementCmdletsInstall.msi The CmdLets are the same ones from the Training Kit – November 2010 release.

• Static Application Switcher is empty after show dekstop

  - by Jepzen

  Im using the Static Application Switcher to configure my ALT + TAB to cycle trough all applications not grouped. So far so good. Then I press Super + D to "hide all normal windows" (show desktop). This setting is from Keyboard - Shortcuts - Navigation. This also works BUT After hide all normal windows has been activated and I press ALT + TAB nothing comes up. I suspect they have been hidden so well that the Application Switcher does not longer sees them. Anyone know if this can be fixed trough settings somewhere?

• Can I install ubuntu on usb hdd without loosing data on it?

  - by Radek

  I have live-usb stick that I can boot latest live Ubuntu from. Then I have 160GB external WD hdd with few GB free of space. My notebook can't have any internal hdd so I was wondering if I can use my external one to install and boot Ubuntu and install new programs, save settings etc. without loosing (or moving around) any data on this external hdd. The best would be if I can somehow use the live-usb. I'm traveling so any "complicated" solution might be bit hard to implement. I do have an access to the Internet.

• HTG Explains: What is the Windows Page File and Should You Disable It?

  - by Chris Hoffman

  Windows uses a page file to store data that can’t be held by your computer’s random-access memory when it fills up. While you can tweak the page file settings, Windows can manage the page file fine on its own. The Windows page file is somewhat misunderstood. People see it as the cause of slowdowns because it’s slower to use the page file than your computer’s RAM, but having a page file is better than not having one.

• suspend not working

  - by Eric

  I am running 13.10 on an ASUS 101-SE netbook. Under "power settings" I have selected suspend when inactive for 10 minutes and suspend when lid is closed. I get a warning when inactive that the computer will suspend due to inactivity, but it does not suspend either from that condition or when closing the lid. I seem to be getting multiple suspend messages as I need to click "cancel" or "OK" many times to get the error window to close when it has been inactive for some time. Anyone have any tips? Thank you.

• No sound after installing a new Graphics Card

  - by Dan

  I've just upgraded my graphics card to an Asus Geforce 210 and now my system has no sound. I've ran Update Manager and the Additional Drivers utility which installed the latest Nvida driver. The graphics card is connected to my TV via a DVI-to-HDMI (DVI at the PC end) cable for the visual connection, and an audio jack from my onboard soundcard for my audio connection. Any ideas on how to resolve this? I ran this command ubuntu-bug audio And it outputted this: You seem to have configured PulseAudio to use the "pci-0000_05_00.1" card, while you want output from "NFORCE - NVidia CK804". I've tired a bit of messing about with the audio settings but can't get anything to work.

• Minimum brightness level is brighter than the levels just above it

  - by greggory.hz

  I'm using a macbook pro 8,1. When I use the brightness keys on the keyboard, decreasing the brightness works until it reaches the lowest brightness level. At that point (when on the lowest level), the brightness is something like 70 or 80% instead of 0-10% (or whatever it usually is). All the other levels are fine. How can I adjust/calibrate these brightness controls? PS: I'm currently using 12.04 but I've had the same issue no later than 11.10 (and I'm fairly confident it was present in 11.04 as well). UPDATE: If I go to System Settings and select "Brightness and Lock" the exact same thing happens, but there is more fine grained control of the brightness. It goes to completely black when the dial is about 10% from the left edge. When it passes that point, anywhere inside that left 10% appears to be about 70 - 80% brightness (there's no change regardless of where the dial is in this section).

• Why are the colors worse on Ubuntu 12.04 than on Windows 7 on my Sony Vaio E-Series?

  - by Simon Hoare

  The colours look "lacking" and ever slightly blueish and rather washed-out and lacking in dimension. Graphics are ok - this page for example looks fine - but if I view something like a news site with high quality photos, the experience is not optimal and is noticeably inferior to Windows 7. Oddly, when I install Ubuntu as a VM on VirtualBox in Windows, the colours look as I expect them to. It's only on my dual-boot version of Ubuntu that they look wrong (not Wubi, although a previous Wubi-based installation had the same problem). Now, I have the proprietary ATI driver and I can use amdcccle to get the colours closer to what they should be, but I can't seem to do anything about colour depth. The depth settings in Xorg are all 24. I tried changing all three mentions of 24 to 32 but was forced into safety mode. Fortunately, I remembered where I'd been tinkering and got the file set back to 24.

• Panel Background color, Transparency and background image don't work with Ambiance theme

  - by Ash G

  As the title suggests. Selecting a background image, color or using the transparency sitting doesn't work with the Ambiance theme. Sections of the panel will take the new settings, but many of the applets including the clock, Indicator Applet Session, Indicator Applet, Rhythmbox icon, Tomboy Icon, Separators and various others retain the Ambiance theme background. This carries over through restart. Also you cannot resize the panel in Ambiance above 24 pixels as the background image doesn't scale. Am I doing something wrong, is it a bug or is it meant to be like that? I really like Ambiance, but am having a hard time using it because of these issues Edit: It seems these issues carry over to Radiance and New Wave as well

• Why do webpages take longer to loo in ubuntu 12.04 than Windows 7

  - by Emil Abraham

  For example, when I click on a Facebook picture, the picture remains pixelated for about 30 seconds, then starts to clear up. Or when I watch YouTube videos, I can't watch them on HD without running into buffer issues. Windows 7 is just much snappier. It might be an issue with the graphics card.

• Need Japanese IME with Dvorak keyboard with 13.10

  - by user916792

  I recently did a fresh install of 13.10 and enabled Japanese language support. In the past this seemed to work seamlessly with my other keyboard settings when I set up my Dvorak keyboard. But this time when I toggle the IME on it uses the standard QWERTY layout. Typing English uses the Dvorak layout as I expect. This just worked for me in the past to the point where I stopped paying attention to what the underlying IME is and I don't recall any special steps other then choosing my keyboard layout and enabling Japanese. Any help would be appreciated!

• How to install drivers for NVIDIA GeForce FX 5200 on Precise

  - by Aaron Simmons

  Ok, I'm a total Linux noob. I was able to install 12.4 without issue, except that it says in the system settings that the graphics card/driver is "unknown". I have NVIDIA GeForce FX 5200, and have not been able to get it installed. I've found the driver at NVIDIA but couldn't figure out how to actually install it. I found instructions that used apt-get to automatically find the current driver and install it, and that came close. At least then it showed up in the 3rd party drivers list. It said it was installed but not being used? And I was unable to find out why that might be, or how to get the system to use it Two questions: 1. CAN/SHOULD my graphics card work with 12.4? 2. If so, HOW? I'm running a 100% fresh install, so what's the step-by-step from there?

• Change login screen to gnome-shell login

  - by Dr_Bunsen

  I was just goofing around in a vm to test what would happen if I purgen unity: sudo apt-get remove --purge unity* I found that I get an startup error, but when I proceed, I got this awesome login screen: It has an sexy effect and is just the gnome style my whole pc has got. So can any one please tell me how I change the default login screen program without having to bother clicking "fix this error" on every boot? Thanks in advance. [edit] This is the error I get, and the only option that works is the, run in low settings for one session.

• Do logged in users need to browse a site over https?

  - by Luke

  I've never thought it was necessary, but a client has requested that all webpages served to logged in users be delivered over HTTPS. Aside from the implementation standpoint, which I don't think I'm going to pursue is there any real reason for this request ? For clarity, the login / logout process, account settings, registration preferences and all user related scripts are served over https. but I can't see the point in my news articles, press releases, events etc... being served in this manner? Am I missing something ?

• Ubuntu doesn't give the intended screen resolution

  - by JMCF125

  I have recently created a Ubuntu 12.04.2 64 bit virtual machine on VirtualBox, and I am not very used to Linux (I used Linux Mint for a few weeks some time ago), so please refer the full name of stuff, not just "the what-not-command". The problem is I can't set the full resolution my computer supports (I think it is 1366 by 768), I have found similar questions and tried most of the respective solutions, thy did not work. If I type xrandr to the terminal I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 640x480 60.0 As you can see, the maximum is too low. And in the settings of the screen (I mean, with GUI) only 1024x768 and 800x600 appear. I don't remember exactly which answer of those questions, but it was one in the terminal (again, with xrandr) that made the resolution I wanted appear (although it gave an error when selected, not even changing to the 1366x768 resolution first and then back to 1024x768).

• Choppy video in vlc even with hardware acceleration on ATI Radeon HD

  - by l0b0

  After installing Catalyst 11.12 and studying instructions (1, 2) to enable hardware acceleration I ended up with the following command: sudo apt-get install xvba-va-driver libva-glx1 vainfo && \ vainfo && \ vlc --verbose 2 --ffmpeg-hw video.1080p.x264.mkv The output confirms that it's using the VA API: avcodec decoder: Using VA API version 0.32 for hardware decoding. But even after a reboot the video still looks choppy. There's no vlc output to indicate that the codec is having trouble, or that it's skipping frames. Any idea what could be the problem? Using vlc 1.1.12 with default settings. Also tried (in sequence): sudo apt-get install libva-glx1 sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core Rebooting No luck yet.

• gnome-control-center can't set display resolution under openbox

  - by Andy

  I'm running Ubuntu 11.10 with Openbox on my laptop. Since I need to plug different external displays into it and Openbox environment doesn't automatically pick them up, I thought the best solution I can come up with is to use gnome-control-center and it's display settings tool from within Openbox. But although this tool does detect monitors correctly, it can't do any change -- clicking Apply button just doesn't seem to do anything. So my questions are: 1) how to get this tool working? 2) how to run "Displays" tool directly from command-line, skipping control center? 3) is there a better way to automatically detect and set resolutions on internal/external monitors under Openbox? Please note I tried arandr too and it doesn't even work for my environment (doesn't detect external display plugging in at all). For what it's worth, my laptop is Lenovo G560, Ubuntu is x64 version with all the updates rolled over. Thanks for your consideration.

• My Rhythmbox plugin can't meet the Ubuntu Software Center "my-app" requirements

  - by allquixotic

  At http://developer.ubuntu.com/publish/my-apps-packages/ the following technical requirements are cited: Technical requirements In order for your application to be distributed in the Software Centre it must: Be in one, self-contained directory when installed Be able to be installed into the /opt/ directory (*) Be executable by all users from the /opt/ directory (**) Write all configuration settings to ~/.config/ (This can be one file or a directory containing multiple configuration files) A Rhythmbox plugin cannot satisfy any of these requirements. Rhythmbox has compiled-in locations where it looks for installed plugins. So, is there no way for me to publish my app in Ubuntu Software Center? Would it have to go into Universe repository (which would require tremendously more work and political maneuvering to get it accepted)? I already have all the Debian package infrastructure built for it, so I have made a PPA for it.

• Large resolution differences

  - by Robin Betka

  I want to develop a game on multiple devices such as PC, Android or IOS. Want it to be in 1080p, but that means a massive scale down for the smartphones. I know how to do that, just render everything on a 1080p rendertarget and then render it on the screen smaller. But what should I do so that the scalling down doesn't look bad and blury? I can't do it vector based or anything because the sprites simply need a specific size. Should I make the sprites power of two size to get some nice mipmapping? And which other settings can I do? Or should I rather go with a lower resolution but then having a little bit worse look PC version? The performance seems not to be a problem for me, so would be sad not using 1080p because of other problems.
