Have a very similar (probably same) problem on my fresh Ubuntu 12.10 installation. My system boots form an SSD drive, and it's using nvidia- current-updates (GeForce 9600 card).
It looks as if things work OK sometimes when I reboot, or I can manually just start lightdm from a ctrl+alt+F5 terminal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066410 Title: lightdm doesn't load correctly on Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1066410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
