Got the same problem on 12.10 on a ivy bridge and intel HD4000, some times after log in black screen, als when I switch users in X.
Kernel show these messages:
[ 241.667578] [drm:intel_cpt_verify_modeset] *ERROR* mode set failed: pipe 0 stuck
This happens on stock 12.10 kernel and on kernel 3.6.2 from the ppa
