I'm new to the forums, so I hope I posted this in the right place.
My installation of Ubuntu 12.04 started going weird a while ago. Every time I plug in the charger for my Toshiba Satellite L750D, the screen goes really dark. I've used the command cat /sys/class/backlight/toshiba/actual_brightness to determine if the settings make the brightness go down. It is however, still at the maximum brightness, 7. I tried re-installing with a fresh installation of Xubuntu 12.04 but it still didn't solve it. Funny thing was this wasn't happening a week ago
Someone mind helping me with this?
