Bug#712933: xserver-xorg-video-nouveau: xserver crashes with geforce 660gt and nouveau drivers

[Jan Christoph Uhde]

Hey Sven,

i have confused the bugs:( And had the wrong driver
driver and libs active.

It should have looked like:

lla /usr/lib/x86_64-linux-gnu/libGL.so*
   0 lrwxrwxrwx 1 root root   14 Jun  7 20:38
/usr/lib/x86_64-linux-gnu/libGL.so -> libGL.so.1.2.0
   0 lrwxrwxrwx 1 root root   14 Jun  7 20:38
/usr/lib/x86_64-linux-gnu/libGL.so.1 -> libGL.so.1.2.0
372K -rw-r--r-- 1 root root 372K Jun  7 20:38
/usr/lib/x86_64-linux-gnu/libGL.so.1.2.0

readlink -f /usr/lib/x86_64-linux-gnu/libGL.so.1
/usr/lib/x86_64-linux-gnu/libGL.so.1.2.0

 readlink -f /usr/lib/xorg/modules/extensions/libglx.so
/usr/lib/xorg/modules/extensions/libglx.so
