I get automatically logged-out every now and then of my PC.
I use Lubuntu 14.04, which has openbox, LXDE. I didn't installed neither openbox nor LXDE by myself.
It happens when I turn-off the wifi, but also at other times.
I am not sure if it's a log-out or just something like Xorg crashing and being re-started.
How can I diagnose and repair this problem?
Would this solution work and what consequences would it have?
From My ubuntu randomly automatically logout after installing openbox:
$ sudo apt-get remove apport update-manager update-manager-core
/var/log/syslog
