Cannot log on to Oneiric after fresh install

[Lars Ola Liavåg]

I made a fresh install over Natty, keeping my home partition untouched. When booted, I feed my password to lightgdm and the screen goes black for a few seconds, then goes back to lightdm. I can do Ctrl+Alt+F1 and login via the shell, but not via the graphical login. Also, I can't stop or restart the machine from the graphical environment. I can log on normally to the guest account and I'm reporting this bug from there.

I've tried reinstalling Oneiric but to no luck. I've tried dist-upgrade from the prompt but without success. I've tried purging and reinstalling lightdm and lightdm-gtk-greeter but that doesn't help either. Please help, or I'll have to reinstall Natty. Right now, this machine is in practice unusable.

Thank you for your bug report, could you add your lightdm.log to the bug?

I'm travelling at the moment but will submit the lightdm.log file when I get back home next weekend. Is the file located somewhere under /var/log?

[Sebastien Bacher (seb128)]

it's in /var/log/lightdm
