Blank screen on power interference with ATI P. driver

view story

http://forums.opensuse.org – My screen goes blank whenever I plug/unplug my laptop ( Toshiba A215 ) laptop having the ATI X1200 graphics card. I started experiencing this after installing the proprietary driver. Any time I logout, it also messes up my display manager-the screen is full of so many colors. Please I need help with this. Anyone out there please assist. Thanks alot (Distributions)
