not sure if it is specific to this laptop, to my general setup, i have
a OpenSolaris 2009.06 version that will hang, after some time of
inactivity. "hang" here means that moving the mouse, or keyboard,
will not reactivate the front end again, and no matters how long i
waited for the reactivation, noth not really sure if it is
application caused or not, but I suspect it very likely due to the
hibernation mode kicking it.
But pinging it and it will respond, and ssh into it is possible as
well. so I ssh in and collected the following info:
