I have installed Knoppix-6.2-CD onto HDD by copying the booted Live-CD system
to mounted another partition. As I liked light and crisp response of it I have
installed Knoppix-6.2-DVD on another partition on the HDD. But I found a little
problem.

Could anyone tell me how to switch off the "screen saver"? So it appears to me
not possible I had to removed "xscreensaver" program for now. Should there not
be a tick box to disable it?---godoten

PS:
I have tried version-6.4.3 also but my GeForce-9800 seems miss-match with it.
It slugs so bad as "not usable"! Neither I can install the NVIDIA's driver.
