Bug#827131: xserver-xorg-video-intel: user connot login in kde

[Jürgen Bausa <Juergen.Bausa@online.de>]

Some more information:

The problem (X-server crashes on user login) only arises, if "xrender" is 
selected and the option "kein Startbildschirm" (=no splash screen) is 
selected.

As long as I select something else than "xrender" (e.g. OpenGL 3.1) in 
"Arbeitsflächen-Effekte" (=desktop effects?) or as I select a splash screen, I 
can login without crashing X.

Interestingly only one of two mashines suffers from this: It is a laptop with 
Broadwell chipset. The other computer has Skylake and works well under the 
same settings. Both run jessie with xserver-xorg-video-intel from jesie-
backports.

Hope this helps.
