running AMD + ATI radeon graphics card - ok on single monitor
(1280x1024), but when extended to two monitors (2560x1024) screen became
fuzzy (horizontal flicker/wobble).

Found this post:

http://www.niccolofavari.com/ubuntu-10.04-lucid-issues-with-external-
monitor-and-ati-radeon-card

"Solution

I just did the following (on a bare install of Ubuntu 10.04)
Fire up the terminal and type

gksudo gedit /etc/modprobe.d/radeon-kms.conf
a blank file will open up. Type in the following.

options radeon modeset=0
Save, exit and reboot."

This worked for me (although no accelerated Graphics).
