Ok I don't really know if this will work for you but it has worked for me a couple times...first get ingame then wait till your screensaver comes on wait a few secs and then touch your mouse or any button to cancel the screensaver...and tada. Its good to set your screensaver to a short period on inactivity so it turns on faster. While ingame dont touch anything and the screensaver will turn on.

I'll post some pics later.
