Xorg Segmentation Fault - seems to be relevant to evdev [closed]
Solution 1:
sudo aptitude install libxfixes3=1:5.0-4
sudo aptitude install xserver-xephyr=2:1.10.4-1ubuntu4.2
sudo aptitude install unity=4.28.0-0ubuntu2
sudo aptitude install xserver-xorg-core=2:1.10.4-1ubuntu4.1
and downgrading some packages from previous answers did the trick for me.
Solution 2:
I can confirm that the offending package on my system is xserver-xorg-core version 2:1.10.4-1ubuntu4.2newyork1.
Downgrading it with
sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4
saved the day for me.
