Maybe the bug is related to ligthdm / upstart rather to xorg, refering to comment in bug report https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/799069

[Franck (alci)]

See message in Xorg.0.log before failing:
[ 4.746] (WW) xf86OpenConsole: setpgid failed: Operation not permitted
[ 4.746] (WW) xf86OpenConsole: setsid failed: Operation not permitted

Searching google with these messages led me to bug #799069. Hope this is relevant.

Maybe also related to bug #982889

Status changed to 'Confirmed' because the bug affects multiple users.

Closing assumed fixed.
