The full workaround sequence is the one I posted in the updated description, not the comments. (There's no such package as just "nouveau", so sudo apt-get remove nouveau won't do anything, and the drivers dialog does a remove not the here-required purge.)
I also have the "nouveau W[ PFIFO][0000:01:00.0] INTR 0x01000000: 0x00000005" messages when running nouveau, sometimes ending in a crash (bug 1243557), and can't suspend with either driver (bug 1333417 / bug 1333431). I don't have HDMI sound so can't test that, but would suggest filing a separate bug for that problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1315156 Title: nvidia-331 selected but nouveau loads To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1315156/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
