# a new enough version which has the -d option.
#
# Also use dbus-run-session to make sure parallel tests aren't failing
# as they simultaneously try to own the "org.gimp.GIMP.UI" D-Bus name
# This is weird but basically on a Debian testing/bookworm, apparently
# the --auto-display (neither the short version -d) option does not
# exist and ends up in error:
# > xvfb-run: unrecognized option '--auto-display'
# There only --auto-servernum works fine.
#
# On a recent Fedora (33 in my case), the later exists but a few of
# the tests fail with some weirder:
# > /usr/bin/xvfb-run: line 186: kill: (53539) - No such process
# There using --auto-display instead (supposed to deprecate
# --auto-servernum) works instead, but only in its short form (-d).
# The long form --auto-display also results in the "unrecognized
# option" error even though the help output lists it.
# Yep it's a huge mess.
