I'm trying to enable the KDE 4.2.1 "desktop effects" using the new OpenGL support in VirtualBox 2.2. My guest is a KDE version of Fedora Core 10.
I've enabled 3D acceleration for the VM and set the video memory to 128MB. I've installed the latest VirtualBox Linux additions.
When I try to enable "desktop effects", I get the incredibly helpful message:
Changing the advanced options does not help.Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check you X configuration. You may also consider changing advanced options, especially changing the compositing type.
My /etc/X11/xorg.conf file was dropped by VirtualBox, and only contains:
Code: Select all
Section "Device"
Identifier "VirtualBox Video Card"
Driver "vboxvideo"
EndSection
Code: Select all
Section "Extensions"
Option "Composite" "Enable"
EndSection
Any ideas? This isn't an area I know anything about...(EE) AIGLX error: vboxvideo does not export required DRI extension
(EE) AIGLX: reverting to software rendering

Steffan
P.S. In case it's relevant, I have an nvidia card in my host machine.
