Two questions: - inevitably, on my TV Set (SONY KDL 3000) this now doing too much underscan. In pixels: without your patch, I used a custom modeline to map 1280x720p to 1220x680p, so I'm 40 pixels down in each dimension. How to fix that? - more of a general drm question I guess: in what way are the connector attributes available on the command line? I couldn't find a complete kernel command line or modprobe invocation. Thanks Marius
