Hello all,

I have upgraded from 10.04 to 10.10 and after the upgrade gnome panel
does not seem to load on one of my screens. I have a dual card X
configuration with two radeon cards and I'm using the open source
radeon driver for X.

When gdm starts the login dialog actually shows up on the left display
but then once I've logged in gnome panel only starts on the right
display. All I see on the left is the desktop background and my mouse
pointer when I move it over to the left display.

Anyone have a clue what's happened here and how to fix it?

Here's some system information:
