How to enable 3D and compiz effects on Debian 'squeeze'?'

[MrRoberts]

Hi all,

I have successfully installed Debian 6.0 64bit 'squeeze' using virtualbox v4.06 and installed the vbox-additions just fine.

I got the full resolution okay as well.

My concern now, is how to enable 3D and using compiz effects?

When I right-click on the desktop and choose 'change Desktop background', I normally get the 'visual effects' tab, but no.

How?

Thanks in advance.

3d in vbox gues settings enabled? Which graphic card has the host?
