Bug#791599: xserver-xorg-video-intel: loss of hardware acceleration after resume
Hi,
thanks for you indication! I tried it with mesa, ending up with an
unusable screen rendering only artefacts after resume.
I updated & upgraded recently and therefore should use the latest
available kernel on testing(3.16.0-4-amd64). I was just wondering how to
install a newer/other kernel without messing my sources?
I found my dmesg outputs the following lines:
[32174.108381] [drm] stuck on render ring
[32174.110149] [drm] GPU HANG: ecode 0:0x00dfffff, reason: Ring hung,
action: reset
& stumbled across this guy reporting similar issues with intel graphic
driver on debian: http://www.moi.vonos.net/2015/05/t550-linux/
best,
Olsen
