happening with the last 3 revs of kernel. In run level 3 - closing
and opening lid brings the text console back to life - but within a
few seconds it blanks - regardless of keyboard activity.

Additional information - it sat all night and woke fine this
morning. However, after using it a few minutes the screen gooes dark.
I can see the windows behind very faintly (no backlight maybe?) and
they are responding to the keyboard - just the screen wont gte bright
- unless i toggle the VC's and then it shuts down rapidly after that
making it impossible to use. I can ssh to laptop and all appears to be
well - no log messages - other than the following which occur if i
manage to get it back bright:

Thanks for any thoughts.
Recent updates enabled some backlight brightness code.. the option for
it in KPowersave is now enabled for me (autodimm to NN% after MM min).
Enabling it doesn't work for me, though - the screen doesn't dim, but
the OS becomes very unresponsive. Similar thing happens when I try to
increase/decrease brightness manually - but that has an effect
brightness and the freezing only lasts 1-2 sec.
Try killing KPowersave or haldaemon - that usually makes everything work
for me
