Description of problem:
The LCD panel of my notebook (toshiba sattelite A65-S1066) gets turned off after
the graphical boot start. Once this happens there is no way to turn it on again.
The problem dosen't happen when I use the previous installed kernel version,
184.108.40.206-115.fc8 in this case.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start up the machine
2. wait for the X to start
Black screen, but with the computer operational, alt-F1 followed by ctrl-alt-del
Normal operation of the screen.
There are other backlight related problems, it is impossible, as far as I tested
to change the brightness of it after the system is loaded. I also have noticed
that it dosen't go off whan I close the lid.
Bug 432587 can be related.
I know that is hard to test this kind of bug without the hardware in question,
so please contact me with any testing you may need to do. I am no kerlnel hacker
but I do know my way around.
I am closing this bug since I have found out that the problem is hardware
related. Sorry for the problem.
