> OK, this is slightly offtopic, but I can start with asking this, is there a setting that can be changed within XFCE to make the vertical refreshrate better, it seems right now that I have 60 Hz and the screen flutters.

Nope, that's an XFree86 configuration issue. I guess it's possible that 
XFCE could have an X config applet - I haven't heard of it, but then I'm 
pretty new to the list.

> I have this box along with a W2K-box on a monitorswitch and in Windows it is rather easy to fix the refresh rate. If this is not possible then I would like to know if anyone can figure out why when I changed in XF86Config to have 1024*768 at 75 instead of only 1024*768 it decided to change the default to 800*600 instead of 1024*768 which I have today. Changing it back to without @75 I have 1024*768 again. I know this latter part is slightly offtopic but somebody can perhaps point me in the right direction. 

XFree86 modes are only resolution, not refresh rate. It'll use the best 
refresh rate it can at any given resolution, given the HSync and 
VRefresh values you told it about your monitor, and/or the DDC-probed 
values (when it asks your monitor directly).

So if you get a higher refresh rate in windows than you're getting in X 
under the same resolution, either you're overdriving your monitor under 
windows or your HSync and VRefresh values in XF86Config are too 
conservative.

Since you're running XFree86 4.3, try the 'xrandr' command to switch 
refresh rates and resolutions on the fly for testing.
