yey, nearly works, the problem is now that instead of displaying across 2 monitors, it make the desktop scroll across one, its ig enough for 2 monitors, but doest activate the second one...

also, how do i set up the refresh rate and monitor type,
specs
both are:

Dell P991
res 1280x1024
refresh rate 85hz

i have fiddled and i still cant fix why it only works on one monitor...

just noticed, ther is a monitor section for only one monitor, do i have to specify both?

Hopefully you didn't copy my config verbatim - the mouse I'm using is usb on that port. Might not work for you: put whatever mouse your old config file was using back in there, then check for the (EE) errors.
-maitre

sorted the mouse, just cant sort out why it doesnt spread aross dual monitors, but scrolls the desktop on one... does the dvi port need to be setip differently, i have a dvi--> vga converter on there...

i tried adding a second screen section to the config file, but to no avail, just doesnt seen to work, rats this is almost the last thing i need to soret before i can move to linus perminantly

post your newst x config and i'll edit it myself and repost - just put your correct configuration in addition (like monitor types, resolutions, blah blah blah)

both monitors are dell p991's refresh @85hz 1280x1024,

thanks mate...

I tried the posted file and that works for me - the only thing would be to get the monitors to do 1280 with Dell specs. I changed it to your monitor's specs with 1280 as a resolution on both and the second monitor RightOf the first. Let me know what this does. cp it to /etc/X11/XF86Config.try and start X using

startx - --xf86config XF86Config.try

and see what it does. The only thing I can't guarantee is the refresh rate be at 85hz. Most likely it will be 75 but to get it at 85 go here:
http://www.hut.fi/Misc/Electronics/f...2rgb/calc.html and you can find a ModeLine for your resolution and refresh...
let me know what happens...
