As you mentioned it, I had a look at this driver. It looks like viafb does it (polarity) just the other way around than geode. So it might be wort a try to change in drivers/video/via/share.h: /* 1200x900@60 Sync Polarity (DCON) */ #define M1200X900_R60_HSP NEGATIVE #define M1200X900_R60_VSP NEGATIVE to /* 1200x900@60 Sync Polarity (DCON) */ #define M1200X900_R60_HSP POSITIVE #define M1200X900_R60_VSP POSITIVE
That fixes the problem - thanks! Let me know if you'd like me to make a patch with that change (I can do so on Monday). It may still be worth you looking at the diagnosis - in particular I think I may have found something that may clean up some of the uncertainty in commit 32fab7bc Thanks Daniel
