Public bug reported: I am filing this against upstart since it seems to affect both lightdm and gdm.
Basically, if I run: sudo service lightdm restart then it will fail with an "X Server already on display 0" message (in gdm logs) It appears that upstart is respawning the DM before the current X session has shutdown completely. If I instead do sudo service lightdm stop <wait a few seconds> sudo service lightdm start it works perfectly. This is 100% reproducible on my 12.10 VM and happens around 1:5 times on my 12.10 installation on real machine. ** Affects: upstart (Ubuntu) Importance: Undecided Status: New ** Description changed: I am filing this against upstart since it seems to affect both lightdm and gdm.
