In my case, a BIOS upgrade solved the problem. For anyone else desparately googling for this problem: it's a Dell Dimension C521 with an nVidia card, and I upgraded the BIOS from 1.0.3 to 1.1.1. Changing kernels, disabling nvidia-driver, removing xorg-driver-synaptic and various other attempts at solving it did not make any difference, but the BIOS upgrade seems to have done the trick.
