Maybe; weird having something like that happen.(maybe it was
something like what appletouch is doing i.g. could not do mode request
error. The problem is it very seldom, every X amount of boots) I can
go back in the kernel and see if I can find out what option really
caused the system to boot properly(hopefully). Also with suspend; I
update to the latest openGl to see if suspend works, but it seems to
be worst with the latest release, i.g. a few days ago I update xorg to
7.3 with sid, suspend would give me a blank screen but no reboot(I
should of left my mouse on the terminal, then once the blank screen
shows up issue dmesg > suspend), now with the latest update with
openGL(today) I receive a blank screen and a reboot.
Maybe openGl needs to have DRI enabled? in order for this to work...
