Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

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

Thank you for your bug report, could you add your ~/.xsession-errors and /var/log/lightdm/lightdm.log to the bug?

I have the same problem. I upgraded from 11.04 to 11.10 and now I can't log on with my user. It doesn't matter if I choose "Ubuntu", "Ubuntu 2d" or "XFCE". Screen turns black for a second and returns to log on screen.

Other users still work though.

I attached ~/.xsession-errors and /var/log/lightdm/

"I attached ~/.xsession-errors and /var/log/lightdm/"

At last I tried it very hard but it does not work to attach a file ?!

Hi Walldorf,

I had to downgrade my OS back to 11.04, therefore I cannot contribute to this bug anymore.

I'm experiencing the same problem and reported a new bug: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/878476

I also uploaded the lightdm log files. Maybe this will help...
Although I think now, it was unnecessary to file a new bug (sorry)
