Subject: [PATCH] ignore vgacon if hardware not present
Date: Thu, 29 Mar 2007 17:46:48 +1000 [thread overview]
Message-ID: <1175154408.12230.195.camel@localhost.localdomain> (raw)
(Did this fall through the cracks? I don't see it in -mm. It's
standalone, and saves some silly code in lguest and presumably others).
==
Avoid trying to set up vgacon if there's no vga hardware present.
