xorg.log

This only occurs with SNA.

gfx at gfx-desktop:~$ cat .local/share/xorg/Xorg.0.log | grep -i sna
[   144.156] (II) intel(0): SNA compiled from 2.99.917-815-g6c1e70ca
[   144.156] (II) intel(0): SNA compiled with assertions enabled
[   144.156] (II) intel(0): SNA compiled for use with valgrind
[   144.176] (**) intel(0): Option "AccelMethod" "sna"
[   144.180] (II) intel(0): SNA initialized with disabled backend

When executing 

   $ xrandr --output eDP1 --rotate left

It will logout and return to the login screen. I'll attach the Xorg.0.log, not
sure if is helpful. Thanks.
