I doubt that it's kde that freezes the box. AFAIK kde doesn't ever access the HW directly. I'd say it's the nvidia driver. Have you tried to up/downgrade the nvidia driver yet? Have you checked that the nvida driver, the kernel and the various openGL bits fit together? *t -- ----------------------------------------------------------- Tomas Pospisek http://sourcepole.com - Linux & Open Source Solutions -----------------------------------------------------------
