Dear experts,

I'm an utter newbie to Linux and am just fiddling aboot a bit, but when trying out the Knoppix CD on my new Medion 8818, I get an error message (most probably screen-related) after having seen the Knoppix CD actually start up

It says:

Mode not supported
H : 15.0KHz V : 18.8Hz

After which the screen actually just completely fails to do anything but stare at me with all its blackness plus this one message.

Can anyone tell me what I could possibly do? Any piece of advice would be most awfully welcome...

CK
