Ok, this bug is back again. Here is what occured.
After unchecking the X11 sync a few weeks ago, I noticed that all of my window menus were missing. While poking around in CCSM to remedy this problem I accidentally clicked on "restore defaults." This caused unity to be disabled somehow. After restoring unity and compiz settings, I tried to log in but got artifacts and the 100% cpu with compiz problem. I just need the computer to work, but it is failing. I cannot use Nouveau because I get the "GPU lockup" issue. Townsend, I installed your ppa and it didn't fix it, there was no change. I've removed (and purged) all nvidia drivers, unity, ubuntu-desktop, lightdm and reinstalled them. I've deleted my xorg.conf and let a new one be made. I'm at a loss with nothing else to do, any suggestions are welcome. Thanks, I unchecked X11 sync again, but there is no change. Unity bar is artifacted and compiz is using large amounts of CPU. I double checked glxinfo output in case something got messed up there, but it remains the same as before. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1424013 Title: Compiz high CPU and UI freeze on NVIDIA after fix for #269904 in trusty-updates Status in Compiz: Fix Committed Status in Compiz 0.9.11 series: Fix Committed Status in compiz package in Ubuntu: Fix Released Status in compiz source package in Trusty: Fix Released Bug description: [ Impact ] Immediately after the fix for #269904 landed in trusty-updates via compiz 1:0.9.11.3+14.04.20150122-0ubuntu1, my 14.04 machine with an NVIDIA card and using the nvidia-304 driver became unusable -- symtoms include compiz process high CPU (100%), UI freeze right after logging in (machine still up, reachable via SSH from the network), and a flood of these messages on the system log. [ Test Case ] Requires a GeForce 6150SE or similar integrated GPU from nVidia. Problem manifests immediately on login. [ Regression Potential ] The fix involves a specific hardware blacklist. Anticipated regressions include fixed support for the specific hard in future nVidia driver releases and potentially additional unidentified hardware affected by this bug needing to be added to the blacklist. Note that there is a manual workaround to the problem consisting of disabling the X11 Sync feature through CCSM. [ Other Info ] This fix was cherry-picked from the Ubuntu "Vivid Vervet" development release where it has been in regular use for some weeks.
