I'm currently logged in over ssh. top/ps show no X processes except for two instances of mplayer (as plugin) in S (sleep < 20s) state.

Xorg still ran about 30 minutes after the freeze, I think I closed the lid at that time (which normally means that the backlight goes off). Setting hw.dri.0.debug to 1 right now doesn't show anything. -- http://www.rene-ladan.nl/ GPG fingerprint = E738 5471 D185 7013 0EE0 4FC8 3C1D 6F83 12E1 84F6 (subkeys.pgp.net)
