UPDATE:
The recent updates break the Xserver. If you have already updated Ubuntu please type the following command:

wget -c http://people.ubuntu.com/~rodarvus/packages/dapper/xorg-server/xserver-xorg-core_1.0.2-0ubuntu10.4_i386.deb

wget -c http://people.ubuntu.com/~rodarvus/packages/dapper/xorg-server/xserver-xorg-dev_1.0.2-0ubuntu10.4_i386.deb

sudo dpkg -i xserver-xorg-core*.deb
