This may be a case of you running the open source nVIDIA driver (rather 
than the proprietary one) on a machine like the Toshiba Tecra M2 (you 
didn't specify your hardware).

If you are on an nVIDIA graphics controler, try enabling the screen 
effects and as such install the proprietary nVIDIA driver.
