I've just installed open SUSE 11.3 with KDE. Problem is, that the screen flashes (turn all black for about two seconds and then back). It repeats at about five second intervals. When the mouse cursor is not moving, it is OK. Hardware used is BENQ G2200W LCD monitor and SiS661Fx onboard graphic card.
I'have installed openSUSE about yeat ago (probably older version) also with KDE and the same HW and everything worked fine. Thanks for answers!
