virtualbox.org

I'd appreciate help getting RDP working. I'm so frustratingly close!

What I've done:
Following advice from other threads I've generated xorg.conf and it includes this:
Section "Device"
Identifier "Card0"
Driver "vboxvideo"
VendorName "InnoTek Systemberatung GmbH"
BoardName "VirtualBox Graphics Adapter"
BusID "PCI:0:2:0"
EndSection

(First I tried putting this and mouse information in files in /usr/lib/X11/xorg.conf.d which I suspect is the correct Lucid way to do it)

What works:
Windows RDP client connects, shows all text mode output during startup, shows desktop background.
Changing RDP display resolution changes VM's display size.

What's broken:
Everything else! Nothing from the desktop ever shows in RDP except the background.

Thank you in advance for any help!

I've discovered if I disable 3D Acceleration it works. Still, it would be nice if someone knows how we can have both 3D Acceleration and working RDP. Thanks.
