Created attachment 21548 [details] [review] Fix LVDS EDID to match all possible default modes (keithp) Please test with Keith's patch which should fix the case when panel has EDID like on your GM45. I know Ma ling has made another patch, but that's for no EDID case. Yes, on GM45 and 945GM with Keith's patch they can list several display modes now.
