    Why is my monitor wacko after the OS loads?

    Finally got Ubuntu (8.04.2) to dual boot with my XP install on my old Dell.
    http://www.uluga.ubuntuforums.org/sh....php?p=7099796
    But now, when I boot into Ubuntu, everything looks right at first. I get the black screen with the ubuntu logo and the orange progress bar. (I guess this is where the hand off to the OS happens.) Anyway, after that, the monitor goes to a static blue field with a bunch of garbage and a half inch square white box for a mouse cursor. I can move the cursor, but there is nothing to do with it. The only way out from here is to reach down and hold the power button until it shuts down. Anybody have an idea of how I can proceed?

    When you see the blue screen with garbage, press and hold CTRL-ALT, then press F1. This will take you to the console. Now login, and type in
    Code:
    gedit /etc/X11/xorg.conf
    Post the contents here.

    Pressed and held CTRL-ALT and then pressed F1 while holding. No response. It is like everything is locked except the square box cursor.

    Reboot and select recovery mode from GRUB. If asked, select to drop to a root shell and execute:
    Code:
    dpkg-reconfigure xserver-xorg
    Just answer yes and ok to all the questions. Then type exit and then select resume normal boot. (or reboot your computer as normal).

    If that still didn't work, get back into recovery mode and open your xorg.conf:

    Code:
    nano /etc/X11/xorg.conf
    Then move to where it says "Device" and add - Driver "vesa"

    right below the "Device" section. Make sure it's Driver without quotes and "vesa" with quotes. Then hit ctrl-x then Enter to save your settings & reboot as normal.

    gedit doesn't work so great in a console, nano however is a solid choice.

    +1 to ktrnka's safemode post, if that doesn't do it, then some time troubleshooting in console may be coming.

    I use nano on Kubuntu, but wasn't sure if gedit replaced it in Ubuntu. Good to know though!

    Thanks ktrnka. Very interesting going through those screens, even if I only vaguely understood a tiny part of it. That eventually got me to the normal login screen. So I have to decide whether to reboot now, or download and install updates. I leaning toward the latter. Might even have a fix in there. Or is there something else I should do first?

    If you are having problems, I would most definitely make sure that the system has been fully updated.

    Once you get your system back up, then you can start "toying" around trying to get the correct driver to work. What is your system's graphics card?
