Details

My configuration:
- xorg using intel driver 1.15.1
- 16:9 LCD display (Samsung)
- LXDM
- user with XFCE session

Actions performed by the user:
- login into XFCE session
- change resolution to 1024x768

Effects:
- system logs out after a couple of seconds, taking user back to login manager
- impossible to login anymore

After some investigation, I found that there was a Xorg crash happening every time a login was attempted (see attachment).

Workaround: edit ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml and replace resolution with 1900x1080

Expected behaviour:
- resolution not accepted by Xorg with graceful error (not a crash)

Not sure where to put this, but since the crash is happening in xorg-server, let's try that.

This is probably fixed with new Xorg and updated Intel driver in testing. You may want to give it a try.
