Hi,
I have a Fujitsu Siemens LCD 15" model 38B1 and while Xserver is starting the monitor tell "frequency not supported"

My video card is Matrox G400 and it is well recognized during the loading of kernel..
I tried many cheat codes like setting resolution screen and xvrefresh but nothing seems to resolve this problem!

I can't understand why with notebook lcd screens Knoppix is good and with many LCD screen not at all.

I read another post about Sony Flatscreen with similar problems.

Can anyone help me?
thanks
Rob
