[SOLVED] Desktop Effects Lost with xorg.conf File

tronayne · 05-04-2010, 07:16 AM

I had to generate /etc/X11/xorg.conf (with xorgsetup) to fix the "crazy colors" problem with VirtualBox; adding

Code:

Section "Extensions"
        Option  "Composite" "Disable"
EndSection

at the end of xorg.conf. The crazy colors problem, at least in my case, seems limited to certain hardware (in this case a Radeon X300 series graphic "card") and VirtualBox is the latest and greatest.

That, of course, results in

Code:

Compositing is not supported on your system.
Required X extensions (XComposite and XDamage) are not available.

Arrgghh!

So, the VirtualBox problem can be fixed with the above, but then ya can't use the display features or you can enable the compositing feature and VirtualBox blows the display all to blazes.

It's not a bug, it's a feature.

So, has anyone managed to figure out how -- or if it's even possible -- to not have the crazy colors problem with VirtualBox and still have desktop effects? Is there some other way around the problem?

I have never had any crazy color problems with virtualbox with the radeon driver in quite a while. As I recall, when I did have that problem I was able to work around it by setting XLIB_SKIP_ARGB_VISUALS=1 when starting VirtualBox. You could also try a newer version of the radeon driver.

I am happy to report that VirtualBox-3.1.8 (VirtualBox-3.1.8-61349-Linux_x86.run) does not exhibit the crazy colors problem with an ATI Radeon X300 series graphic controller; installed it, removed /etc/X11/xorg.conf, reboot (general principles), start it up, boot a virtual machine, no crazy colors, shut down the virtual machine and VirtualBox, no crazy colors.

Yippee.
