I tried to edit the /etc/X11/XF86Config-4 file earlier, under monitor section>modes with "1280x1024_70.00". When I tried to save the changes I got an error, something to do with not enough space to save changes.

Typing kxconfig (root) gave me the option of changing the resolution to 1280x1024, after starting new session....bingo! Quick and simple, worked a treat, cheers. Didn't get much time to look around in kxconfig, but looked much more comprehensive than the right click desktop>configure option.

Thanks
