<pre>Hi Kenneth,
I upgraded my Ubuntu trusty to today's state of the xorg-edgers PPA:
xserver-xorg-core 2:1.15.1-0ubuntu2
xserver-xorg-video-intel
2:2.99.911+git20140507.18416b51-0ubuntu0ricotz~trusty
libegl1-mesa:amd64 10.3.0~git20140514.8a9f5ecd-0ubuntu0sarvatt~trusty
libgl1-mesa-dri:amd64 10.3.0~git20140514.8a9f5ecd-0ubuntu0sarvatt~trusty
$ glxinfo | grep Mesa
client glx vendor string: Mesa Project and SGI
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.0-devel
OpenGL version string: 3.0 Mesa 10.3.0-devel
I'm still experiencing problems. Garbage screen output disappeared, but the
screen is stuck for 5-20 secs every 1-3 minutes.
The kernel ring buffer says:
[ 333.738942] [drm] stuck on render ring
[ 333.738951] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 333.738952] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 333.738953] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 333.738954] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 333.738955] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 339.736311] [drm] stuck on render ring
[ 339.736354] [drm:i915_context_is_banned] *ERROR* context hanging too fast,
declaring banned!
[ 348.720483] [drm] stuck on render ring
[ 354.729941] [drm] stuck on render ring
[ 360.727429] [drm] stuck on render ring
[ 360.727558] [drm:i915_context_is_banned] *ERROR* context hanging too fast,
declaring banned!
[ 439.102608] init: tty1 main process ended, respawning
[ 468.674648] [drm] stuck on render ring
[ 647.707294] [drm] stuck on render ring
[ 716.739191] [drm] stuck on render ring
So I'm still having trouble, even with xserver 1.15.1 and a recent mesa
version.
Regards,
Benjamin</pre>
