I found https://bugs.freedesktop.org/show_bug.cgi?id=69982 which suggests booting with nouveau.config=NvMSI=0 I haven't tried it yet, as I've been currently running under boot parameter nouveau.noaccel=1, and the system hasn't crashed yet. |
Created attachment 110381 [details] shows display corruption I had this issue on linux-3.12.0-rc2 and thought it had been fixed in linux-3.12.0-rc3, but it just happened again. I dock my laptop after using it for two days undocked. The resume is normal, and I start the netork. I enabled the second monitor with xrandr --output LVDS-1 --auto xrandr --output DP-2 --auto xrandr --output DP-2 --primary --output LVDS-1 --right-of DP-2 Both displays are funky -- parts of windows in blocks are displayed all over, like in the attached picture. I attempt to switch back to one monitor xrandr --output LVDS-1 --primary --output DP-2 --off xrandr --fb 1600x900 The second monitor turns off, but the primary display is still messed up. If I stop Xorg, and it restarts, the following messages are in the kernel log [276069.408906] nouveau E[ PDISP][0000:01:00.0] chid 1 mthd 0x0080 data 0x00000000 0x000b5080 [276247.160437] nouveau E[ PDISP][0000:01:00.0] chid 1 mthd 0x0080 data 0x00000000 0x100b5080 [276415.088799] nouveau E[ PDISP][0000:01:00.0][0xc000857d][ffff88021d083640] channel stalled
