    Question 12.10 3.5.0-17-generic - No login screen

    Hi,

    I upgraded to 12.10 a few days ago. All was well, but looks like an interrupted updated caused problems.

    When I boot the comp, I get random "" characters all over the screen. Then I get a few lines "KVM: Disabled by Bios". After that the screen goes black, and the keyboard no longer works. I never get any kind of login screen. (I'm not trying to use KVM anyways)

    I SSH into the comp, and its up and running via SSH. Its just never letting me see the login ui screen to start the desktop environment. I tried 'gdm' but it doesn't work, i imagine because I can only call it over a SSH terminal and not on the actual comp itself.

    I've been able to get all my updates completed, so I'm stuck on what to do next.

    Thanks
    Markus

    Looks like it has something to do with GDM or lightdm. I re-installed Xorg which prompted me which I would rather use, gdm or lightdm. Choosing gdm at least brought me to a text-based login. Then I tried to run lightdm and it crashed on me again giving me a blank black screen.

    sudo service lightdm start
    you may need to use nomodeset in your boot line from grub
    Code:
    sudo sed -i 's/quiet splash/quite splash nomodeset/' /etc/default/grub;sudo update-grub;sudo reboot
    undo:
    Code:
    sudo sed -i 's/ nomodeset//' /etc/default/grub;sudo update-grub;sudo reboot
    alot of people think the 3.6.1 kernel is better than 3.5 one [link to post with install script]
    it is a shot in the dark but it may help, more likely a gpu driver issue, which card/driver are you using?

    Thanks for the code, but what exactly am I supposed to do with it?

    Am I supposed to run both lines of code you have in order, or make a change to a grub config file?

    thanks

    line 1 makes the changes to grub for you, line 2 undoes the change if you need to revert it

    I also tried booting from 12.04 disc - I get to the Menu of options, but then when I click anything 'try w/o installing', 'install' etc, it goes black with random "" characters on the screen.
