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 On 06/07/15 21:22, Julien Cristau wrote: > On Mon, Jul 6, 2015 at 16:44:37 +0100, olsen wrote: > >> Package: xserver-xorg-video-intel >> Version: 2:2.99.917-1~bpo8+1 >> Severity: important >> >> Dear Maintainer, >> >> *** Reporter, please consider answering these questions, where appropriate >> *** >> >> * What led up to the situation? >> The problem becomes apparent for example if I start chromium >> and try to move the whole browser window by holding down the alt key + the >> mouse, resulting in almost slow motion. >> Similar effects with Iceweasel on various websites e.g. >> googlemaps.
