Xorg.0.log with SNA option
Bug description:
Resume from suspend on Intel GM965/GL960 (GMA X3100) with DDX SNA fails and
causes a reboot, but resume works fine if the non-default UXA DDX acceleration
option is used.
System environment:
-- chipset: Intel GM965/GL960 (GMA X3100)
-- system architecture: 32-bit (i686)
-- xf86-video-intel: 2:2.99.910-0ubuntu1.1
-- xserver: 2:1.15.1-0ubuntu2.1
-- kernel: 3.13.0-39
-- Linux distribution: Mint 17 Quiana, Cinnamon, 32-bit
-- Machine or mobo model: Acer Extensa 5220, model: 5220-051G08Mi MS2205
-- Display connector: standard laptop lcd
Reproducing steps:
- trigger bug with Option "AccelMethod" "sna"and resume from suspend often
causes reboot
- avoid bug with with Option "AccelMethod" "uxa" and resume from suspend seems
reliable (no reboot noticed yet after several tests)
Example config to test with
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
#Option "AccelMethod" "uxa"
Option "AccelMethod" "sna"
EndSection
Probability: Very frequent. I'd say only 1 in 10 resume attempts (with Option
"AccelMethod" "sna") worked and the rest failed and caused a reboot.
Attempted to follow the guide here:
<a href="https://01.org/linuxgraphics/documentation/how-debug-suspend-resume-issues-0">https://01.org/linuxgraphics/documentation/how-debug-suspend-resume-issues-0</a>
- resume from S3 suspend to RAM without mdm (display manager) running appeared
to work fine, e.g. 'echo mem > /sys/power/state'
- the default suspend via menu GUI in Cinnamon often caused the resume bug to
surface
- S4 hibernation worked fine and didn't seem to trigger the bug
- given the system reboots, unable to login via another terminal or ssh and
cannot capture dmesg after, etc
- have not had time to try use intel_reg_dumper or intel_gpu_dump output
Found several similar bug reports for Intel 965 / X3100 type laptops and Intel
drivers in Ubuntu 14.04 and or Kernel 3.13. My suspicion is newer Intel video
drivers have caused a number of regressions in the latest Kernels, especially
with older Intel Chipsets. These are similar bugs, but there fixes don't appear
to work in my case:

Logged bug specific to Mint here, but realised this is quite probably an
upstream bug and probably not specific to Mint:
