>Subject: [PATCH] Restore old VT switch code
>
>Calls for enabling and disabling outputs were removed from the VT switch
>routine when RandR support was added. Presumably, this is because the
>server already sets DPMS properly on a VT switch. However, DDX code can
>undo what the server does so it seems best to keep the explicity calls.
