• Asus A8N-SLI soundcard/headphone not recognized/working

  - by Remon

  I have an Asus A8N-SLI with built-in sound-card which in the front has headset connection. Alsamixer V1.0.25 says Card: HD-Audio Generic Chip:ATI R6xx HDMI. Only option it gives is S/PDIF nothing else. I can only select the Generic sound-card others are not available. It seems it is not being recognized by Ubuntu. My technical skills are limited and I have searched for similar problems but could not find a solution. Any help in how to proceed forward is therefore greatly appreciated. I also have a windows focus problem with Gnome3 and Unity for which I will make a new question. Between those two problems it works like a charm as always. Though I'm only going to upgrade the laptop to 12.04 if I have the desktop running smoothly.

• My desktop disappeared, how do I get it back?

  - by sunny

  I have Ubuntu 12.04 LTS. This morning when I logged into my Ubuntu, after login screen the complete desktop was empty, the only operation I could perform is right-click and open terminal. What I've tried: Ctrl+Alt+F1 unity --reset : didn't work From terminal unity --reset : didn't work And from login screen selecting Ubuntu 2D and that also didn't solve the problem. My laptop is Toshiba SA-60 onboard ATI graphic card with 1 GB RAM. Please tell me how to solve this problem. I don't want to reinstall Ubuntu as whenever I install a I/O error pops up, forget about that. I don't want to reinstall Ubuntu. Please help.

• ubuntu 12.10 slow application load upon restart

  - by Adam

  new ubuntu user. after boot (boot is quite fast), opening applications such as firefox, libra, system settings, takes close to 10 seconds to open. after the application is loaded in RAM, the application opens fine. the system feels snappy, quick. when i have two FIREFOX open, unity is snappy in showing me the two windows side by side. but upon bootup, loading the application takes 10 seconds. there is not much hdd activity. fresh install. its the same for system settings and browsing system settings. when system settings is opened for the first time (10 second), and i click for example Color, it will take quite long to open the color settings. hardware: i3 4gb ram radeon 5770 250gb sata gigabyte h55m motherboard i am using ubuntu straight out of the box, no propriety drivers. 64 bit. i have reinstalled OS, and still the same.

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken?

• Mic not working on Lenovo G470

  - by Caveman

  I used a Lenovo G470 laptop (Core i5 2410M processor, AMD Radeon 6370M and 2GB DDR3 RAM) and I installed Ubuntu 12.04. I can't get the microphone to work. I encountered this type of issue before in my old Acer Aspire One with Ubuntu 10.04/10.10, and installing PulseAudio Volume Control and tweaking a little solves the problem. I tried the same solution to no avail in 12.04. I tried entering the alsa in terminal and my mic is not detected there. Does anybody encountered a similar problem? Any help will be greatly appreciated.

• Problems after installing Ubuntu LiveUSB on my 2nd HD

  - by user113106

  I decided to create a Ubuntu USB installer using the Universal USB Installer, selecting a Ubuntu 12.10 ISO. I selected my D: drive, my NON-windows7 carrying drive as install. After this I Re-booted my system and my PC began to Run the Ubuntu Boot-startscreen every time I power up the machine, giving errors like this: Root=Unknown I used my girlfriend's laptop to create, on the exact same way, a real! USB Ubuntu installer. Booting from that USB, picking the option Run Ubuntu from this USB I get the following error: http://postimage.org/image/63qkv98c1/ Let's try installing it from that USB to a Hard-Disk: http://postimage.org/image/usqbwymfx/ As I said: I do not have the Option to pick my Boot-section, at this very moment I can only access to the Ubuntu installation and nothing else. I've read about 90% of other Questions that could've been related, but I could not find a solution. BTW I'm running a Acer Aspire 2Quadcore 4gb DDR 2 Ati Radeon HD, 64bit and I've set my Bios OS-usage from Windows to "Others"

• How to fix "The system is running in low-graphics mode" error?

  - by jokerdino

  Note: This is an attempt to create a canonical question that covers all instances of "low-graphics mode" error that occurs to a user, including but not limited to installation of wrong drivers, incorrect or invalid lightdm greeters, low disk space, incorrect installation of graphics card like ATI and Nvidia, incorrect configuration of xorg.conf file while setting up multiple monitors among others. If you are experiencing the "low-graphics mode" error when trying to login but none of the following answers work for you, please do ask a new question and then update the answers of this canonical question as and when your new question gets answered. When I try to boot into my computer, I am getting this error: The system is running in low-graphics mode Your screen, graphics cards, and input device settings could not be detected correctly. You will need to configure these yourself. How do I fix the failsafe X mode and login into my computer? Answer index: The greeter is invalid

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• ubuntu is becoming more unstable

  - by Michael Hennessey

  I find ubuntu extremely unstable with mouse freezes (that can be corrected with control key), constant Compiz crashes ( with ATI non proprietary drivers also), problems installing drivers ( why would I want a video driver that fails to play most games, with loss of function of so many games (BZ flag?? has been around for years with no problems). I get the feeling that there is so one in your dept who is intentionally making poor and unstable choices for less than altruistic reasons. Whatever happened has been worsening ever since Unity became a choice. I have tried Kubuntu, Mint, Lubuntu and several other variants with similar poor results. Be aware I have used Ubuntu for many years.

• ubuntu 12.04 html5 video jumps out of fullscreen when I change volume [closed]

  - by user68477

  Often I can't play html5 videos at all until after a relogin. I have a lenovo t500 with an ati hd3650. My sense is that it's the pop up notice that kills fullscreen. The "popup" notice refers to the notice that always pops up in the upper right hand corner when ubuntu announces something. In this case it pops up when I change the volume and video immediately jumps out of fullscreen. The question is: can I do something about the lack of fullscreen in youtube html5 or is it something I just have to accept?

• Linux 3.10 améliore la mise en cache pour les SSD et offre de meilleures performances pour le CPU et le GPU, la version stable disponible

• Ubuntu 12.04 on MBPro, Early 2011, options

  - by sthysel

  I have a 2.2 GHz i7, 4GB MacBook Pro 8.3, AMD Radeon HD 6750M 1024 MB, Early 2011. As far as I see I have two options, running Ubuntu on this hardware: VMWare/Virtualbox and Ubuntu in a VM, I already ordered a 16G RAM upgrade for this. Wipe OSX and go Ubuntu native, with 16G RAM, yay ! I'm kinda leaning towards option 2 as I tend to spend 90% of my time in dev VM's at work anyway. All my other machines at home, and most at work are Ubuntu/Linux as well. I have a Mac mini on standby for the odd Itunes backup/sync. If I don't have to keep OSX around, I would like to get rid of it altogether. Ubuntu support on Mac hardware seems to be a hit and miss affair as far as I can tell. Does anyone have good success running a recent version of Ubuntu on this hardware ? Thanks

• Massive crash and kernel panic after updates yesterday, what now?

  - by Ghost

  Got 12.04 on an AMD+radeon machine, everything was running fine until last night when the update manager installed new packages, and now the moment I open a browser (firefox, chromium, anything) it crashes instantly. It says warning: at build/buildd/linux-3.5.0/arch/x86/kernel/smp.c:123 native_smp_send_reschedule+0x5b/0x60() Pid: 2432, comm: chrome_dbthread tainted: G D 3.5.0-2generic #2-ubuntu I already tried uninstalling the packages from the update log, didn't solve a thing. Depending of which browser I use I get a different reaction, like a complete freeze instead of a text console crash. Ideas? I really don't know what to do.

• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

  I am a new linux user so i am not familiar with what actually is needed to check. When shutting down or trying to restart i get a screen with yellow letters and the system does not close or restart. I have to shut down manually. I can't type all the numbers but i will give the last ones. [90102.232650] [ end-trace 435966f5b367871 ] this seems to have happened after i downgraded the xorg so i can get drivers for my ATI card(4850HD). The suspend command works fine.

• Radon HD 6870 compatibility with Ubuntu 11.10

  - by mhost

  Does anyone have experience with the XFX Radeon HD 6870 on Ubuntu 11.10? I've googled and the best I could find was someone getting the card to 'work' on linux. Nothing specific about ubuntu and this card. Specifically, I want to be able to use the full 1900x1200 resolution and watch 1080p movies. If yes, was it very complicated to get working? Note: I do not have the card yet, I am debating buying it, but would like to know beforehand because there is a restocking fee if I have to return it. Thanks.

• Setting up multiple monitors KDE 12.04

  - by Brandon

  I have 1 1920x1080 display that I am using as a primary display, with a 1600x900 display off to my side. I have tried to set up the smaller display to be positioned to the right of the larger display, but I can't. The only option that works is to use it as a clone. When I connect the smaller monitor to another DVI port on my AMD Radeon HD 6950, it doesnt work at all. I can provide more information if needed. Thank you!

• No sound coming from HDMI

  - by cypwrx

  (Ubuntu 12.04 x64) After looking at other questions (here and other sites) and trying their respective answers, I am still unable to get the hdmi audio out working. I have downloaded the recommended hardware drivers for my card (radeon hd 4350), made sure that the card is not muted in alsamixer, and set it as the correct output device in sound settings. I have also disabled the onboard sound devices in the bios menu. In aplay -l, it shows my hdmi card as hw:0,3 Even after doing sound tests I still cannot hear anything. Any suggestions? Not sure where to go from here, I am fairly new to linux.

• Minecraft program frame rate is very slow

  - by Cade

  I have recently downloaded Minecraft to Ubuntu 12.04. It launches and plays successfully, however- the frame rates for the game are extremely slow. They never go past 9 fps and usually drop below 3 fps. I have been a Windows XP user for years and have just recently switched to Ubuntu, so I'm not an expert with this OS. My video card is a Diamond Stealth s60 with Radeon 7000. I don't know what other information you guys need but if you ask for it, and would please tell me how to get to it, I will tell you as soon as I can. Thanks for your help.

• Getting trayer to work with dual screen setup

  - by Ikke

  I'm using XMonad as my window manager, and want to use trayer as a icon panel for things like nm-applet. The problem was that the panel wouldn't appear on the top of the screen. If I set it to the bottom it just appeared. After a lot of trying, I found out it is because my xorg.conf is setup for dualscreens, and probably the trayer panel is spawned outside my view (I currently have only a single screen, but I switch a lot). After manualy tweaking the xorg.conf file to allow for just one screen, the panel appears on the right spot. These are the things I had to modify: Section "Monitor" Identifier "0-LVDS" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1366x768" Option "TargetRefresh" "60" Option "Position" "0 0" # Was 1280 256 Option "Rotate" "normal" Option "Disable" "false" EndSection SubSection "Display" Viewport 0 0 Virtual 1366 768 # Was 2646 2646 Depth 24 EndSubSection The problem is ofcourse that I can't use my dual screen setup anymore. Is there a way to force trayer on the right position even with the dualscreen setup?
