It seems you're running quantal with the wrong nouveau driver. The nouveau driver you're running is the xorg-edgers version for precise. So, switch to xorg-edgers for quantal and if that doesn't solve your problem then purge xorg-edgers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1039125 Title: [drm] nouveau :02:00.0: PFIFO_CACHE_ERROR - Ch 2/2 Mthd 0x0800 Data 0x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1039125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I made some further investigations for the nouveau driver today. Kernels 3.5.0-10 to 3.5.0-12: The issue is present with a corrupted screen and massive logging of PFIFO_CACHE_ERROR messages. Kernel 3.5.0-13 The issue seems gone, i.e the nouveau driver again! It seems that the fixes for kernel 3.5.0-13 (two bugs) also fixed this issue! My guess is the framebuffer recycling issue being fixed. The issue also is present in kernel 3.6, but never mind as 3.5 will be shipped for Quantal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1039125 Title: [drm] nouveau :02:00.0: PFIFO_CACHE_ERROR - Ch 2/2 Mthd 0x0800 Data 0x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1039125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@dino99 vblank only works for some nvidia graphic cards (not mine) but worth testing as a workaround. I guess .udeb packages exist in the repos but not visible as those are special stripped ditto packages for special use to save ram.

Instead of Ctrl-Alt-Backspace one can do the following: - Press Ctrl-Alt-F2 - login with your username and password - - Retart lightdm with: sudo service lightdm restart + - Restart lightdm with: sudo service lightdm restart Workaround 3: Remove the grub splash option. Not sure it's the libdrm-nouveau2 package but remember that one was introduced for DRM in the time frame for this bug.
