Either use synaptic(i think it was Kynaptic in KDE) or in the terminal/Konsole type this command: sudo apt-get --purge remove nvidia-glx linux-restricted-modules-`uname -r`..
nvidia-glx wasn't installed on my system - nothing to remove
sudo apt-get --purge remove linux-restricted-modules-2.6.12-10-smp - worked OK
