I've done an HDD installation of Knoppix 3.3 and all went well. But the monitor refresh rate is set too low. The problem is that when I go to the Control Centre->Peripherals and click on display, the system tries to open something for a few minutes and then just nothing happens. All the other submenus in the Control Centre opens fine.

How can I fix this / How can I change my refresh rate?

I should perhaps state that I'm using a Intel D865GBF mobo with Intel Extreme Graphics onboard and I don't think Knoppix loaded a correct driver for it. Does anyone know where I can get a proper driver (Intel's website only have drivers for RedHat and SuSe)?
