I installed Knoppix on a 2nd hd in order to keep XP on my machine. Almost all of the hardware is recognized properly, yet the screen's size changes when I switch to Knoppix form XP and viceversa: I have to adjust (from the monitor's OSD) the zoom factor which, for XP is around 60 and for Knoppix around 20.
Can this be solved because it gets annoying sometimes (I switch the OSs 3-4 times a day)?
The monitor is a 17" Philips.

Thanks in advance.
