6699	VirtualBox aborts after changing the video driver	James Moe		"opensuse v11.2 linux 2.6.31.12-0.2-desktop x86_64

The host was running the open source radeon video driver; it was mostly good. I then got a program in Windows that is quite graphics heavy, and complained about the GPU acceleration being unavailable.

It suggested in  discussion [http://forums.virtualbox.org/viewtopic.php?f=7&t=30960&sid=5a0b8ff99d9a254929447057a748a1b7] that the ATI flgrx video driver was required for Direct3D support in a Windows VM. I downloaded the latest version and installed it per the installation notes.

Since there was no observable difference in the Windows VM performance, I reverted to the original video driver. All VMs abort at startup now with the original radeon video driver. I MUST now use the flgrx driver even though I do not like it (it has a few annoying features that cannot be modified).
