I am having similar issues with dual monitor support and CPU usage after update.

Well, i ended up finding that those flashes was caused by vgaswitcheroo switching from gpu to gpu(using dmesg), so i was able to set this feature off using grub and setting radeon.runpm=0 and the problem seens to be fixed!

Tried a multiple ways to make each head (DVI, VGA and HDMI) of the card, but without success. So I added a new NVIDIA FX5200 dualhead VGA card and it works with separate graphic cards, but tearing down the graphics card into two consoles which used to be possible earlier (http://netpatia.blogspot.se/2009/07/multiseat-with-nvidia-card.html and ...

It turned out I hadn't looked hard enough. In my Xorg log file, I found the following entries: [ 23.735] (II) LoadModule: "glx" [ 23.762] (II) Loading /usr/lib/x86_64-linux-gnu/xorg/extra-modules/extra-modules.dpkg-tmp/libglx.so [ 23.822] (EE) Failed to load /usr/lib/x86_64-linux-gnu/xorg/extra-modules/extra-modules.dpkg-tmp/libglx.so: ...

have you solved this problem? I had exactly the same issue on my laptop when I installed Ubuntu 14.10 I tracked it down to a bug in the kernel, at least in my case. Try using my kernel see if it fixes it. Suspend has been working with no issues for me for about a week now so I'll push the change upstream when I have a chance. ...

The only way for me was this: Ctrl+Alt+F1 and this command sudo apt-get purge fontconfig-infinality and a reboot.

For me the solution was enable virtual desktop in wine config using the resolution of my pc, for example in my notebook I set the resolution to 1366x768 and used Alt+Tab to go back to game. I must press Alt, if I don't the letters won't work correctly.

I would suggest trying to reconfigure the xserver on your computer. You might try sudo dpkg-reconfigure xserver-xorg If that doesn't work I would try doing the same for fglrx-updates.

Here is a workaround for flickering like this. First, install Compiz Config Settings Manager (CCSM) by typing into your terminal sudo apt-get install compizconfig-settings-manager, or search for it in the software center. When it's finished, open it up and scroll down to the Utility section. Make sure "Workarounds" is enabled. Click on it, and scroll down to ...

AMD has dropped support for the Radeon HD 4000 series, which is what you have. You might still be able to use this driver, but it probably won't be an update for what you have.

Try this: Put the line GRUB_GFXPAYLOAD_LINUX=auto just below the line #GRUB_GFXMODE=640x480 in the file /etc/default/grub. I had the same problem and this fix completely solved it. (Source)

My final solution for this was to swap my Radeon graphics card for a nVidia one I had just bought for a machine in my shop. Fixed all my problems related to Steam. So, atleast to me, Radeon cards are not very Linux friendly.

Unsure if it is useful, but please check the BIOS settings, if touchpad is disabled there? Also, many notebooks have Fn+key combination to disable the TP. Couldn't you press this combination unintentionally? Try to boot from LiveCD - does it detect the TP?

I had this problem after an Ubuntu update this morning and, rather than re-installing Steam, I found out that I could instead "reset" it. This fixed my problem and was super simple.

Even though this is a few years old, I see there is no accepted answer. I have a Sapphire Radeon HD 5450 card that drives three monitors. My monitors are VGA 1440x900, HDMI 1680x1050, and VGA 1440x900. The ports are VGA, HDMI, and DVI. Therefore, for the DVI port I use an adapter. You would need to use the open source xorg drivers for best results. No ...

Make sure you installed Ubuntu on your main file disk. Otherwise that may cause some problems. Try playing around with your power settings in Ubuntu. In my case with Lubuntu I would go to Menu > Preferences > Power Manager but you may have something different. If that doesn't work, your computer may not be able to go into suspend/standby mode. Have you ...

Following command to install the pulse audio volume control sudo apt-get update sudo apt-get install pavucontrol do a search for the app or execute pavucontrol. This is not the same as the volume control on your panel. You will have more control over card selection and assigning devices. Also, sometimes unplugging and plugging the HDMI back in ...

I'm glad you fixed it, but people should know there's an easier way. I had to use it repeatedly when I was trying to use the Unity desktop. From the desktop you can get to the console, which is a Unix-terminal like text environment. The console will make you log in with both user name and password. Use the Ctrl-Alt-F1 shortcut keys to switch to the ...

Two things may be wrong. With the second possibility usually you don't make it to the login screen, so I kind of doubt that's it, but a corrupt install remains a possibility. This sort of sounds like a common Unity malfunction. The forums are full of Ubuntu 14.04 users trying, usually in vain, to make Unity work. If it'll let you, and it sounds like ...

I'm experiencing the same thing on my own Inspiron 17R: Color Problems on New Install of 14.04 A band-aid is to boot with kernel-mode-setting disabled. Add nomodeset after GRUB_CMDLINE_LINUX_DEFAULT= "nomodeset" in /etc/default/grub). I'm pretty sure this disables hardware accelerated graphics, but if you're not doing graphics intensive work it at least ...

Have you checked your GPU heatsink? You may want to clean it out with some canned air. For me, my CPU was idling ~100 degrees C before I opened my case to check it out - the heatsink was completely clogged with dust. As for your driver issue, I'm not sure why your driver is listed as "ati 2600xt." I'm using a [Radeon HD 7850] with a the updated ...

Turns out I already had a suitable driver. I just needed to use the xrandr command to expand my desktop across two monitors.

I had the same problem as you mate. I also have ATI Radeon 8600M on my Dell laptop. I came up with two workarounds for this problem that I will describe, so you do not have to bang your head. I know what I am going to propose you is not direct solution for the problem. It is the best workaround that I have found so far from my experience. I will be very ...

Solution: I solved it (meaning I haven't had the Low Graphics Error now for about 10 reboots) by installing drivers for my GPU (2x 280X AMD cross-fire). I've done this previously with no success, but I guess I then had tried some other things before installing the drivers that messed it up. To help others with the same problem I'll explain what I did in ...

I had the same problem, found a workaround here: http://ubuntuforums.org/showthread.php?t=2149791. xrandr --output LVDS1 --auto --left-of HDMI1 --output HDMI1 --auto --scale 1.0001x1.0001 (Adjust outputs accordingly) The important thing is to change the scale of your output. Beats me why this works, I hope they'll come up with a proper fix.

After you are in the command line interface (i.e. following the steps as stated by addictcook below choosing failsafeX login option) you can just directly run sudo aticonfig --uninstall However, the above command will fail to uninstall the AMD driver if you have installed it with the .deb packages, which was the case for me. So I had to run sudo dpkg ...

That's why you're supposed to use the driver which are distrubuted through Ubuntu repositories. When you download driver from Nvidia site, it will modify kernel. The way you are supposed to get to the nvidia drivers (though not newest) is to open Software & Updates from your Ubuntu Dash, click on the Additional Drivers tab and pick the driver from the ...

For ubuntu 14.4.2 - I have just copied cp -r /usr/lib64/fglrx /usr/lib/. Because aticonfig will checked permissions for fglrx folder, and ln -sis always rwxrwxrwx I know that is not good variant, but all works)
