    Unhappy Upgrade to 12.10 - can't log in through lightdm or gdm

    I've already been through a number of threads, so I'll summarize my situation and my attempts so far:

    I upgraded from 12.04 to 12.10 - apparently without error. When I get to lightdm or gdm, I enter my information then get returned to lightdm or gdm. I use gnome-shell as my environment.

    I have already done:

    Moved .Xauthority to .Xauthority.backup
    Changed from lightdm to gdm (and back)
    I've gotten to tty1 and done:

    sudo apt-get install --fix-broken
    sudo apt-get update && sudo apt-get upgrade
    sudo dpkg --configure -a

    None of which have helped - there were no prompts for either process, although apt-get update upgraded linux-headers-generic and linux-image-generic. I've looked through dmesg, and there are no warnings or critical messages.

    I feel like from the other messages that I'm a victim of a partial upgrade, but searching on that gets me the same information. I'm out of ideas. Help!

    Hi!, elsewares,

    As your ' linux-headers-generic' was updated, try Purging and Re-installing your video driver.

    There is a lot of trouble about with 12.10 updates not properly installing that file and the video driver - both AMD & NVIDIA- failing to create the needed kernal module as a result.

    Chao!, bogan.

    yeah it's deinitely a partial upgrade you're encountering....gnome-shell is not a part fo the upgrade....

    ctl-alt-f1 and do 'sudo apt-get install gnome-shell"....
