When choosing the "Separate X Screen" option to use my projector in Jaunty, the second X screen seems to exist, but the display is totally black.

Also the mouse pointer when moving from screen 0 to 1 freezes at the edge of screen 0 and then a second one appears on screen 1 (the pointer is the only thing visible on screen 1) This transition was seamless in Intrepid.

When I click Restart from the FUSA, the second X screen is briefly visible in all it's glory before the computer shuts down. So it is there! It's just hiding from me :-(

The GDM only displays on screen 0 as well.

I've experimented with TwinView and XCinerama and they still work fine.

Confirmed this in both the 32-bit and 64-bit versions of Jaunty.
Confirmed in 64-bit using version 180 and 173 of nvidia driver.

I think I was using 173 in Intrepid (which makes me think it's not the nvidia driver at fault) but I haven't re-booted my Intrepid drive to confirm that yet.

I spotted this thread on the ubuntu forums, where a few others appear to have the same issue:

I'm up for some experimenting if anyone has any suggestions...
