Blank screen on startup after installing Ubuntu 8.10? Try this fix

Compiz (a fancy window manager for Linux) is probably causing the problem.

Reboot your computer. When GRUB pops up, it may say "Press ESC to enter menu", or alternatley you may be kicked to the menu if you have multiple OS's installed. Either way, when you get to the OS selection menu, select the menu option (kernel choice) that has the word "Recovery" in it.

Once that's loaded, choose the "drop to root terminal" option (to that effect, the exact wording may be different) from the imtimidating blue menu that pops up.

From there, type the following command.

Code:

sudo apt-get purge compiz compiz-core

Now reboot your computer just in case.

Hope that works...
