Gnome Panel dissappears with dual screen configuration

[dave97232]

Boot up Ubuntu Intrepid Ibex latest packages as of Nov 3 with dual monitors. GDM login looks fine (duplicated on both screens), but when log in nothing is displayed. The default background is a bit corrupted but no Gnome Panel drawn. If I unplug the second monitor and CTRL-ALT-BKSP restart X11 login things are fine with single screen. If I then plug in the second monitor, go into System->Preferences->Screen Resolution to turn it on, the problem is repeated.

Main Monitor: Laptop LCD: 1400x1050 resolution.
Second Monitor: VGA 1600x1200 resolution.
Dual Monitor configuration: non-cloned, Second Monitor to left of Laptop LCD.

Other Configuration Information that may be relevant:
1. I switched my Window Manager to xfwm4 (install xfwm4, then go to gconf-editor desktop->gnome->session->required_components to change to /bin/xfwm4)
2. I edited the default panels to remove the bottom one and put everything I care about on the top one. Panel shows on the Laptop LCD screen.

After configuring the system as above, with dual-monitors and xfwm4, things look fine at first. Dual monitor support looks fine. Then power down the machine. Power it back up, and the problem then happens.

p.s. Thanks for looking into this! :)

dave97232, can you please check if the bug Sebastian mentioned is probably the same you reported (bug #290935)? Thanks in advance.
