This bug is still a problem for me too, however there is a work around. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/779166
The following command should make the screen bright again, I recommend you use an external monitor when trying to correct this issue. sudo setpci -s 00:02.0 F4.B=00 However, restarting, playing a game, activating from (stand by/hibernation) makes the screen dim again. One option is to add the above command to the rc.local, but this only allows the screen to be bright from a clear reboot. The other option is to add this command to root's crontab, on a timer of every 1-2 minutes, that way if your screen is dark for any reason, you only have to wait 1-2 minutes for it to be fixed. I hibernate my laptop when I'm not using it so I usually have to wait 1-2 minutes after its finished loading to use it, so i cannot say that this bug is fixed on any level. I also don't know the long term impact of running this command every minute, just incase the screen is dim.
