Dual display - windows will not move fully to TFT, part of the windows stays on LCD

[smblackwell]

I have a Dell D620 running FC5 which when docked has an extenal Flat Panal Monitor at it's disposal.

I have configure xorg to do dual output with the Laptop LCD being the primary device. But for some reason when I go to move windows from the LCD to the external TFT, the windows will not move fully to the TFT. For some reason a part of the window will stay on the Laptops LCD.

Does anyone know how to fix this, my xorg.conf is below

Cheers

I had that working perfectly on my FC5 installation on my HP nc6120, but experience the same now I just upgraded to FC6test3.

How does it work if you log in as root instead of a user?
My system is very unstable concerning dual displays at the moment, but it seems to work perfect under root on my last test, but not as user. This might be a lead for somebody to what it might be. I will open a topic as well on other problems I have since my upgrade.

After doing some more investigation, I have found out that it seems to be Gnome desktop causing the problem and I cant seem to work out how to fix it.

So I have switch to a xfce desktop which works perfectly and after the short while of getting use to the xfce panel and right click menu I think it's better than Gnome.

If anyone does manage to fix the problem with Gnome, then please let me know.

Cheers
