Bug Description
I'm running 12.10, and since installing the stable release in October I didn't install any upgrades. This week, after installing the latest upgrades, lightdm stopped working: the Xserver starts, and dies immediately, leaving me on a tty7 with remains of log messages.
If I log in and manually restart lightdm, it works.
I think I am not alone in this, as a user had reported exactly the same back in July in the xubuntu-users mailing list:
https:/
I've done some tests and:
- If I disable plymouth (by removing splash from GRUB_CMDLINE_
- If I press 'esc' to exit plymouth before lightdm triess to start the bug also goes away
Looking at the lightdm log, it seems that it decides to kill itself:
...
[+1.22s] DEBUG: Starting Light Display Manager 1.4.0, UID=0 PID=1138 (notice the pid)
...
[+5.59s] DEBUG: New display ready, switching to it
[+5.59s] DEBUG: Activating VT 7
[+6.53s] DEBUG: Greeter start authentication for knuckles
[+6.54s] DEBUG: Started session 1862 with service 'lightdm', username 'knuckles'
[+6.54s] DEBUG: Greeter start authentication for knuckles
[+6.54s] DEBUG: Session 1862: Sending SIGTERM
[+6.54s] DEBUG: Started session 1863 with service 'lightdm', username 'knuckles'
[+6.54s] DEBUG: Got signal 15 from process 1138 (signal to die received from itself!!)
[+6.54s] DEBUG: Caught Terminated signal, shutting down
...
This is what leads me to believe that the bug is in lightdm.
