Subject: [PATCH] drm/radeon/kms: Report vga connector is connected according to ddc_probe
Date: Thu, 12 Nov 2009 14:13:53 +0100 [thread overview]
Message-ID: <1258031633-4914-1-git-send-email-jglisse@redhat.com> (raw)
On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.
