OK, the "xvfb-run --help" on Fedora shows:

use the X server to find a display number automatically
Well, the "--auto-display" option is not necessary available on
other systems. So we should stay with "-a" option but drop "-n".
On Ubuntu 22.04.1:
$ xvfb-run --auto-display
xvfb-run: unrecognized option '--auto-display'
$ echo $?
1
Shouldn't that be sufficient to let configure.ac check whether that
option is available and generate the respective xvfb-run command line,
i.e. the XVFB variable, to use it if yes?
Unfortunately, I do not have an xvfb-run available that recognized the
--auto-display option.
Maybe configure.ac could even use "xvfb-run --help | grep --
'--auto-display'", no?
