Slackware guest system in VirtualBox: libGL error


Hi,

I'm running Slackware 14.1 as a guest system in VirtualBox 4.3.14 running on an Elementary OS 0.2 host. I did quite some fine-tuning, but I wonder if I haven't forgotten something. When I'm starting a minimal graphical session (WindowMaker), I make a test with 'glxinfo | grep -i render', which displays the line "direct rendering: Yes", but also a couple of LibGL error lines: "failed to load driver vboxvideo".

Did I miss something here? See attachment to get a better idea.

It looks like one of the virtualbox kernel modules can't find libGL.so. Maybe you have a 32 bit version but no 64 bit (or vice versa)

The host system is 64 bit, the guest is 32 bit.

Hmmmm. Looks like this is a bug in VirtualBox. Annoying showstopper.

You're missing something like dkms or headers kernenel-dev, because it didn't build the module.
Try re-installing guest additions & post error.
Also did you run the tests from the link?

No, the module has been built OK, and lsmod even shows it's loaded. That's why I'm puzzled.

OK, I found the culprit. Apparently, it's a bug affecting VirtualBox 4.3.x, reported on version 4.3.8. As a workaround, I've downgraded VirtualBox to the 4.2.x branch, version 4.2.26. Everything works perfectly now.

Side note: downgrading VirtualBox is a major PITA.
