Description andreas-kde 2016-02-01 19:20:54 UTC

Environment:
Debian Testing (20160201)
-triple head dual gpu (nvidia onboard 8200 + gtx260)
 -nvidia 340.96 drivers
-xinerama enabled
debian kde 4.14.3

kwin crashes imediatly after logging in, followed by crashes of other kde components, even bug reporting tool crashes prior being able to send data. Thus I can't provide a backtrace.

xfce4 works without issues.

Reproducible: Always

Steps to Reproduce:
1. Use Triple head nvidia pc with xinerama enabled
2. login

Actual Results:  
"empty" screen after closing all crash handler windows.

Expected Results:  
Working desktop environment.

Same HW does work on debian 7 + 8 with minor issues (xinerama related positioning issues)

Qt5 (still?) hard depends on xrandr, your setup is unsupported (that's why drkonqi and every Qt5 client will segfault as well)

KWing *had* unconditionall calls into xrandr itself, that should be fixed itr. (but we won't know for sure until you pass the crashy Qt sections, ie. the Qt bugs are fixed)
