I have the same problem. it's not /tmp for me either, that looks fine. On login, the gdm window goes away, then the X server appears to crash or exit, then comes back to the login window. I tried switching to kdm, behaves the same way.
One oddity that might be related is that it's running on the 8th virtual terminal, not the 7th as normal. -- Can't log in after upgrading https://bugs.launchpad.net/bugs/136529 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
