I tried Knoppix on my second computer. I don't see any IRQ error at the installation , but after a while the screen goes black. Two times , every 15 minutes I think , is this a screensaver or something? When I press a button on the keyboard everything is normal again...

How can I turn off the screensaver and monitor energy
settings?

When I boot Knoppix from the harddisk , I see the IRQ error in the console. It is the same error I get on my other computer when I am installing Knoppix on the harddisk.

One more question , the Knoppix installation is complete when the process bar is at 74 % , is this correct?
