[PATCH for-8.2 3/3] ui/console: fix default VC when there are no display
Posted by marcandre.lureau@redhat.com 1 year ago
From: Marc-André Lureau <marcandre.lureau@redhat.com>

When display is "none", we may still have remote displays (I think it
would be simpler if VNC/Spice were regular display btw). Return the
default VC then, and set them up to fix a regression when using remote
display and it used the TTY instead.

Fixes: commit 1bec1cc0d ("ui/console: allow to override the default VC")
