--- Comment #3 from Pekka Paalanen <ppaalanen at gmail.com> ---
Patches should be sent to mailing list with 'git send-email'. However, the
proposed patch does not use any familiar names.

It seems compositor-drm.c's output naming could probably use even more fixing,
looking at drmmode_create_name() in
http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/drivers/modesetting/drmmode_display.c#n1358
.

OTOH, I suppose we should leave MST support for another time, and just fix the
current stuff.

Comparing our name table in compositor-drm.c to that of -modesetting's, it
seems it should have the same issue, Weston is missing a couple of entries, and
not just DVI but also TV and HDMI entries might theoretically produce
duplicates.

Weston is also using slightly different names on some. Makes me wonder what
convention we should follow.

The actual meanings I think are authoritatively defined here with the
DRM_MODE_CONNECTOR_*:
http://cgit.freedesktop.org/mesa/drm/tree/include/drm/drm_mode.h#n201
The name tables just follow that exact ordering.

Have you tried if Xorg with -modesetting driver has the same identical name
issue? If they have, you might want to file a bug for that too.
