I've got a dual head machine using 2 ATI Radeon X300 cards (both running at 1280x1024). The gnome desktop works great, I've can use both monitors, move stuff between them fine.

I enable remote desktop and try to connect using vnc, but I only see the left screen and right screen shows up completely black. I think something is wrong with the vino-server set up that isn't letting a connecting vncviewer see the right screen.

If I create a separate vnc session, say :1 and set the geometry to 2560x1024, I can see everything if I use the -fullscreen option with the vncviewer.

What am I missing with vino-server?

This is on a fedora machine, ignore my signature links.
