Same here on a thinkpad T400S. I've tried upgrading the kernel to 3.6.3 and the graphical drivers with xorg-edgers version to no avail.
Until this bug is fixed I added 'respawn' to the lightdm upstart script so that it respawns until it works (sometime it works the first time, sometimes the second time and sometimes more restarts are needed). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1054136 Title: Quantal Beta 1 fresh install : No lightdm graphical login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1054136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
