Comment 3 Wang Zhenyu 2008-09-27 22:31:39 UTC

No, don't try this patch, try current git master instead.

Comment 4 Wang Zhenyu 2008-10-07 22:55:51 UTC

Looks we have a macmini hack in sdvo get_modes, that we'll try to steal edid from VGA if that's disconnected, but shouldn't affect here as we have VGA connected, right? Please test with current master.
