Adding that extra mode takes me back to where I started n - ie task bar in the middle of the screen. The only difference that I can see in the Xorg.0.log file is this:

(II) RADEON(0): Output DVI-1 using initial mode 1152x864
(II) RADEON(0): Output DVI-0 using initial mode 1280x1024
after xf86InitialConfiguration

whick looks like the resolution is set correctly but whoever draws the task bars (Nautilus?) didn't get the message.

Interestingly System->Preferences->Hardware->Screen Resolution still shows the default resolution as 1152x864 at 60Hz and System->Administration->Display also shows the current resolution as 1152x864 and 1280x1024 is not an option. Somebody is confused.

Hmmm.... It was working just fine in FC6.

I'll see if I can find that thread.
