Comment 6 for bug 260744

I'm affected by this bug after upgrading Kubuntu Oneiric to Precise by changing every "oneiric" occurrence to "precise" in sources.list and then running a dist-upgrade (because my environment was not triggering an available upgrade notification).

Something weird has happened in PAM, since it's trying to look for my user with a wrong uid.

I can login with "startx /usr/bin/startkde" only, but then I would get authentication failures everywhere I'm asked to input my password for root privileges, unless I run the same commands from terminal with sudo.

I wrote in the Kubuntu forums: http://www.kubuntuforums.net/showthread.php?58623-Can-t-login-via-KDM-after-upgrading-to-Precise
