When switching from battery to ac or back, screen goes black
I guess it's my turn.
I have an Acer amd64 dual with an atix1600 vid card. I've had this happen on various distros, so it's not distro specific.
When I go from AC to battery or vice versa, my screen goes black, I have to ctrl_alt f1 then back to f7 to get my screen back. I can post my xorg.conf if requested, but I have had this prob before and after a kernel upgrade it went away. No clue at all. I'm curious if it's an acpi setting.
I've googled this many times, but not really seeing anything similar.
