Black screen after upgrading from Ubuntu 10.04 to 10.10

After upgrading my Ubuntu from 10.04 to 10.10 i got only black screens or weird distorted graphics on my Acer Tracelmate 220 laptop with Intel 830 graphics card.

The solution for this misery:

1. Boot in recovery mode with root console and log on
2. change the xorg.conf settings to "vesa" ("enable VESA": https://wiki.ubuntu.com/X/Bugs/Mavericki8xxStatus)
3. Then follow those instructions and set the "nomodesetup" for grub: http://ubuntuforums.org/showthread.php?t=1613132

This gave me back X11 and Gnome - finally! :D
