I know this is a really old thread, but I was having problems uninstalling the Guest Additions on Ubuntu 10.10 Maverick Meerkat (My host machine is Windows 7 64-bit). Because Ubuntu 10.10 doesn't use an xorg.conf file by default and this is added during the installation of the Guest Additions, it needs to be removed in order for Video to work after the Guest Additions is deleted. Your first step would be to remove the guest additions package: Then, you're going to want to delete the xorg.conf file (ONLY if you haven't made one yourself; remember, ubuntu 10.10 won't have one by default): Finally, if you're using Compiz, you'll want to reset to default settings (without this, you won't be able to start the X Server, because it's looking for an xorg.conf file): I used these steps when I was done using VirtualBox to boot up an existing Ubuntu partition (on a Dual-Boot system), and I wanted to be able to boot back into Ubuntu. I hope this is able to help someone!

Please don't play a necromancer here. Reviving old topics that are no longer relevant is bad netiquette. I've therefore split your post to a new thread.

The GA from the PUEL release now have an uninstall script, so you don't have to manually remove the modules and such. An xorg.conf isn't generated either. If you run the OSE version, or install the OSE additions while you run the PUEL version, you're on your own to clean up the mess, as it's not advised, nor supported, to combine those two.
