Actually, X does not work at all with nouveau, after suspend/resume. I see a picture of the screensaver, but "graphical seat" does not seem responsive at all (no Alt-F1, not even Num Lock LED switching). Worse, in this state, the system cannot be rebooted anymore (in software, with "shutdown"). And even a hard reboot doesn't fix things: I still still the boot messages (BIOS, sysv), but when X starts, the screen stays black and no way to switch to console (Alt-F1). In dmesg, I get the following suspicious messages: > [ 47.912532] nouveau E[ PGRAPH][0000:02:00.0] TRAP_MP_EXEC - TP 0 MP 0: > (unknown enum 0x00000002) at 000000 warp 6, opcode 00000000 22882831 > [ 47.912551] nouveau E[ PGRAPH][0000:02:00.0] TRAP > [ 47.912561] nouveau E[ PGRAPH][0000:02:00.0] ch 2 [0x0007b45000 > Xorg[3463]] subc 2 class 0x502d mthd 0x08dc data 0x00000000 > [ 48.081476] nouveau E[ PGRAPH][0000:02:00.0] TRAP_MP_EXEC - TP 0 MP 0: > (unknown enum 0x00000002) at 000000 warp 6, opcode 00000000 22882831 > [ 48.081491] nouveau E[ PGRAPH][0000:02:00.0] TRAP > [ 48.081500] nouveau E[ PGRAPH][0000:02:00.0] ch 4 [0x000797f000 > gnome-session-c[4148]] subc 3 class 0x8397 mthd 0x1b0c data 0x1000f010 > [ 54.303084] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle > timeout fail > [ 54.303091] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS : 0x00800001 > BUSY MP > [ 54.303095] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS0: 0x00000000 > [ 54.303098] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS1: 0x00001000 > MP > [ 54.303100] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS2: 0x00000000 > [ 56.305363] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle > timeout fail > [ 56.305367] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS : 0x00800001 > BUSY MP > [ 56.305370] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS0: 0x00000000 > [ 56.305372] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS1: 0x00001000 > MP > [ 56.305374] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS2: 0x00000000 > [ 58.306263] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle > timeout fail > [ 58.306265] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS : 0x00800001 > BUSY MP > [ 58.306268] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS0: 0x00000000 > [ 58.306270] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS1: 0x00001000 > MP > [ 58.306272] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS2: 0x00000000 > [ 60.308417] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle > timeout fail > [ 60.308428] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS : 0x00800001 > BUSY MP > [ 60.308436] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS0: 0x00000000 > [ 60.308440] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS1: 0x00001000 > MP > [ 60.308445] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS2: 0x00000000 > [ 61.266253] RPC: AUTH_GSS upcall timed out. > [ 61.266253] Please check user daemon is running. > [ 62.309417] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH TLB flush idle > timeout fail > [ 62.309426] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_STATUS : 0x00800001 > BUSY MP > [ 62.309435] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS0: 0x00000000 > [ 62.309439] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS1: 0x00001000 > MP > [ 62.309444] nouveau E[ PGRAPH][0000:02:00.0] PGRAPH_VSTATUS2: 0x00000000 > [ 64.319439] nouveau E[ PGRAPH][0000:02:00.0] TRAP_MP_EXEC - TP 0 MP 0: > (unknown enum 0x00000002) at 000000 warp 6, opcode 00000000 22882831 > [ 64.319454] nouveau E[ PGRAPH][0000:02:00.0] TRAP > [ 64.319463] nouveau E[ PGRAPH][0000:02:00.0] ch 4 [0x000797f000 > gnome-shell[4357]] subc 3 class 0x8397 mthd 0x1b0c data 0x1000f010 > [ 171.412133] nouveau E[ DRM] GPU lockup - switching to software fbcon In this state, NumLock and shutdown work, though.
