I'm affected by this bug as well. Card is ASUS ENGTX580 DCII. Distro: Arch Linux X.Org: 1.16 mesa: 10.2.4 xf86-video-nouveau: 1.0.10
I have a Korean Monitor so there are some errors about missing EDID in the dmesg, but even without an xorg.conf nouveau detected the 2560x1440 resolution and Gnome 3 looked fine until it locked up. The lockup happened, while I was typing a terminal in Gnome 3.12.2. Came out of nowhere. I attached my dmesg log. I rebooted and got another lockup very quickly but this time without the long list of nouveau E[ PDISP] messages. Channel value is the same, but process is Xorg.bin not mutter-launch. read fault at 0x4391800000 [PT_NOT_PRESENT] from PGRAPH/CTXCTL on channel 0x005fb79000 [Xorg.bin[909]] -- 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/925048 Title: [GTX 580] X seems to hang a login prompt -- PFIFO errors in dmesg To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/925048/+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
