Heres the printed out values: [ 3.185455] Rop nr: 6 [ 3.185457] Gpc nr: 4 [ 3.185460] Tpc nr for gpc 0: 4 [ 3.185463] Tpc nr for gpc 1: 4 [ 3.185466] Tpc nr for gpc 2: 4 [ 3.185469] Tpc nr for gpc 3: 4 I tried setting them all to 1, the card freezes pretty much immediately after logging into kwin (which is when I suspect opengl rendering starts), although oddly enough there was no read fault in the dmesg. I also tried setting them all to 2, and it froze pretty quickly too, and the machine became completely unrecoverable. Note that I also tried using the blob firmware with all values set to 2, so I think not having them at their natural amounts simply pisses the card off. Didn't try directly disabling stuff with 0x22584/0x22588, not entirely sure where I would do that even. -- You received this bug notification because you are a member of Desktop Packages, 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 Status in Accelerated Xorg driver for nVidia cards: Confirmed Status in “xserver-xorg-video-nouveau” package in Ubuntu: Triaged Bug description: Machine boots to and displays the lightdm login banner, as soon as the cursor flashes in the password box output stops.
