Replicating video freeze

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am now able to replicate my video freeze by lowering and raising
windows at a fast pace. When doing this my screen will 'flicker' for an
instant and at times will continue to flicker. The flicker consists
actually of two areas on the screen. I've tried to capture a screen shot
when the continuous flicker is happening but as soon as I raise the
window for Gnome screen shot the flicker stops. Tonight when lowering
and raising windows at a fast pace the freeze occurred. Running 

cat /sys/kernel/debug/dri/0/i915_swizzle_info outputted:

bit6 swizzle for X-tiling = none
bit6 swizzle for Y-tiling = none
DDC = 0x00200010
DDC2 = 0x00300030
C0DRB3 = 0x0030
C1DRB3 = 0x0010

Running cat /sys/class/drm/card0/error outputted:

no error state collected

The freeze occurred at 20:07:39 my syslog shows this for that time
period

The flicker also appears when switching between window applications such
as from window 1 Evolution to window 2 Firefox or any other window. I'm
currently running the kernel in my sig per recommendations from the
Ubuntu kernel team and will add this to my bug report there for bug 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1497627 I also have
a bug report at freedesktop.org
