The screen on my laptop is b0rked, so I'm wanting to plug a monitor inot the video out thing at the back and use it with a crt. It works, but for some reason the bottom.. maybe 20% of the screen is blank. The image isn't distorted or anything, it's like it just decides it can't be bothered drawing any further down.

I've tried messing around with the video setup, changing the monitor to a standard 1024x768 crt, but it just does exactly the same thing. It will draw the full screen if I'm in command line mode.

If I can't fix this I'm gonna have to put windows xp or something one it.. and you don't want that , do you? ;-)

FWIW I'm using kde 3, fedora core 2, gdm , the laptop, I guarentee you never heard of, but it has an sis650 graphics card and the monitor is a crappy old ibm g74.

I'm guessing there's an x config file somewhere that I need to monkey around with. I'm not bothered if it screws up the display on the laptop screen because it has a tasty looking crack in it anyway.
