Hi all!

Im very new, i installed Ubuntu After getting a vista machine (bad move) and i feel i am going to enjoy it alot.

Now as for my problem well its screen and graphics.

Everything on my screen is huge i have tryed to change resolution but it only has one 800x600 and mine is 1440x900. so this is a problem and i dont know how to fix.

I have been trying to install ati radeon with all the help from the sticky post here but this is not working either. i have ati radeon hd2400 PRO i have tryed to reconfigure my xserver but tis does not help either at one point i rbooted and the screen was very fuzzy and double vision.

Any ideas what i can do.

Please help!

Thanks

Ben.
