Oh dear. It looks as if I'll have to work out how to do it myself. I know there's a way of starting up programs on boot, but I've completely forgotten what it is. Will do some research.
I did some research. The responsible utility VBoxClient is part of the package virtualbox-guest-x11. It is started from the script /etc/X11/Xsession.d/98vboxadd-xclient during X server startup. You could try to execute the checks there manually, i.e. run lspci -d 80ee:beef (should show something like "VGA compatible controller" and test -c /dev/vboxguest echo $? (should give 0 for success) Best regards, Michael
