yes, this is mostly normal

seems that the video driver on Stretch is not capable of running in a rootless X server,
while the virtualbox driver implementation is.

Now, upstream (vbox) patched it and told me they were sending patches to the video
driver too, but I'm unsure when and if it will eventually reach sid/Stretch.

So, installing guest-* stuff, makes everything works in both root-X and rootless-X.

your approach is quite correct, the solution should be to patch the Debian video driver,
because vbox is already fine.

Would you mind updating the wiki with your findings?

this is probably the commit that fixed the xorg issue

xorg maintainers, are you aware of such patch/video issue? I don't remember the exact package, but since
lots of people run virtualbox it might be nice to have it working out-of-the-box, without having
to install additional vbox drivers

what do you think?
