Does your laptop have an ambient light sensor? I had one go bad on an Acer laptop that
would cause trouble. In my case it was flaky and would randomly dim/brighten. It has
been a while now, but I think I had to short it out to get things working well.
No ambient light sensor that I have ever discovered. I have a few of
these in service and have taken them all apart at times, though not the
monitor piece. But I have had to read the maint docs and they do not
mention one.
Recently, I have had to have blackout tape over my camera to enter a
facility where I have contract work. Since they got me a contracter ID,
I no longer need to do that, but have not taken the tape off, as I do
not use the camera...
I took that tape off and no change.
Need to find a program in Xfce that uses the camera to test it out again..,
