I also had a similar problem. I think the solution is given in http://ubuntuforums.org/showthread.php?p=2513954
Go to terminal and open the xorg.conf file: gksudo gedit /etc/X11/xorg.conf and add this line to the Section "Device" or the Section "Screen": Option "AddARGBGLXVisuals" "true" and save the file. This will solve your problem. Restart the X server with ALT+CTRL+BACKSPACE and you will be OK. Additionally, you can add these two lines, they will improve the perfomance of your desktop: Option "DisableGLXRootClipping" "true" Option "DamageEvents" "true" Also, you can add this line, but it is somewhat experimental and maybe you'll experience lockups: Option "RenderAccel" "true" -- Fails to start with window decorations https://bugs.launchpad.net/bugs/97231 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
