1) Please press ctrl+alt+f1 or ctrl+alt+f2 and made login with your user and password then type:

sudo rm ~/.Xauthority

give your user password you will not get any screen feedback when you type your password so type then press enter.

Reboot with this command:

sudo reboot

and try to login

2) If previous solution doesn't works please redo previous ctrl+alt+f2 step made login and then type

sudo dpkg-reconfigure lightdm
sudo reboot

if this still doesn't works redo the step (2) and choose gdm and retry.

I am having the same issue, but the local users work fine, but accessing an account from NIS fails with the quick black screen. Logging into the NIS works fine from the console (ctrl-alt-f#), and my NFS files are all there, but the problem only exists when trying to access accounts on the 10.10 NFS/NIS server through the lightdm login screen on the 11.10 client.

I'm too facing this problem. My workstation is a NIS client and I can't login if I use lightdm. This doesn't look like a ubuntu specific issue but more related to light dm.

 gdm / wdm / xdm work fine with nis.

Happened to me. Tracked it down to a bug in my .profile file. For some reason this didn't prevent me from logging in at a console, but lightdm failed and threw me back to the login screen. Look in your ~/.xsession-error file (I think that is the file...)

Bug in .profile for me too. I had an invalidly named function :todo as well as other bash bugs.

 I had the same issue and solved it with "sudo chown -R username:group /tmp"

Can you help with this problem?
