Comment 16 for bug 350306

Hi,

I have the same error.
Option "AccelMethod" "XAA" -- does not help
The error repeats when trying to change a user:
1. boot
2. login user1
3. switch user to user2
the screen blinks several times and only a garbage on it afterwards.
The Laptop does not response on the keybord, only the MagicKeys, or gdm restart via ssh

The same behaviour occurs with the programm Stellarium. For example when changing settings of the programm.

dmesg after error (via ssh from other PC):
[ 144.642566] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0
