I'm running an AMD64 system with a NVidia card and I managed to get things working again (without a reboot) by re-installing xserver-common, xserver-xorg-core, xserver-xorg-video-intel and nvidia-current through GDebi (used nautilus to go to /var/cache/apt/archives). Hope that helps someone else, sorry I didn't have time to narrow it down to just one package!
