https://bugzilla.kernel.org/show_bug.cgi?id=62681 Bug ID: 62681 Summary: linux-3.12.0 rc3 nouveau: screen corruption after resume Product: Drivers Version: 2.5 Kernel Version: 3.12 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: richcoe2@xxxxxxxxx Regression: Yes Created attachment 110381 --> https://bugzilla.kernel.org/attachment.cgi?id=110381&action=edit 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 -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
