xenocara doesn't work with fbtab:
[...]
if (d->windowPath != NULL) {
/* XXX not working because of pledge() */
Debug("login_fbtab %s %d\n", d->windowPath, geteuid());
login_fbtab(d->windowPath, pwd->pw_uid, pwd->pw_gid);
}
So unfortunately you still need to add such things to
/etc/X11/xenodm/{Give,Take}Console.
