Bug#422746: xserver-xorg-core: Backlight turns off
Package: xserver-xorg-core
Version: 2:1.3.0.0.dfsg-3
Severity: normal
Since a recent update, my backlight has started shutting off. I haven't noticed
anything in common about the times that it has shut off so I'm sorry I can't
give more useful information about that.
But, if I switch to a VT, the backlight comes back on and I can see the console
screen. Then if I switch back to X, the light will operate normally. There was
also one instance of it happening when waking the laptop up from sleep. I put
it back to sleep, waited a minute, and woke it back up again---the backlight
came on as normal.
If I find out that it's a hardware problem I'll make sure to report back.
I'm including my embarrassingly sloppy and crufty xorg.conf below as well.
