Screen saver session turns blank ("white")

Hi, Configuring with KDE, my screen saver starts (say with Forest) correctly but after a couple of minutes the screen turns out blank - I mean "white" (with quotes) because is not really white color but a white brightness with a darker periphery. With typing or mouse movement the normal screen (not the screen saver images) comes back. I use Suse 9.2 and KDE 3.3 (Toshiba Satellite 5105-S501 with NVIDIA GeForce4 440 Go + 32MB DDR video memory) and generally Thanks in advance for your attention and possible help Eduardo -- Eduardo A Nogueira, MD, PhD Professor of Internal Medicine Cardiac Catheterization Laboratory University of Campinas School of Medicine Campinas, Sao Paulo Brazil
