    Black screen when booting new install of 11.10, cannot access tty1

    I installed 11.10 on my desktop. After the intro screen from the Intel motherboard, I just get a black screen. I've looked at the various fixes online which would require access to tty1 but hitting Ctrl+Alt+F1 doesn't work for me. I just remain stuck at the screen. I have an AMD Radeon HD 6450 video card.

    I've re-booted without any USB devices plugged in and tried the upgrade from 11.10 to 11.10 option as suggested in a forum. Still get the black screen.

    So now I would like to try:

    Code:
    Hit Ctrl+Alt+F1 at the blank screen to get you to a non-X terminal (tty1)
        Login in with your username and password
        Change to root with: sudo -i and enter your password
        mkdir -p /run /run/lock
        rm -rf /var/run /var/lock
        ln -s /run /var
        ln -s /run/lock /var
        reboot
    And if that doesn't work:

    In Ubuntu 11.10, /etc/grub.d/10_linux line 70, it checks if the word "splash" is present in GRUB_CMDLINE_LINUX_DEFAULT. This GRUB_CMDLINE_LINUX_DEFAULT can be modified in /etc/default/grub. So changing this line:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    to
    GRUB_CMDLINE_LINUX_DEFAULT=""

    I should have removed "splash" only but I also would like to see all the message while the machine is booting up.

    Next up, is add the following towards the end of /etc/default/grub:
    GRUB_GFXPAYLOAD_LINUX=text

    Ok I am not so familiar with this one. But I believe what it does is to force it to run in text mode instead of doing KMS functionality built-in the kernel.

    Now, to update grub.cfg run:

    sudo update-grub

    Then reboot the machine, like:

    sudo reboot
