Picture quality I meant is what I think after some bad experience with Fedora 13, 14 and now rawhide 15 it is backlight, it is not solid or smooth like on opensuse 11.1. On all fedora it looks like backlight flickers, and it doesn't make picture solid (smooth). I check everything and compare everything I can. It is not font, or DPI because both OS on the same laptop and I made exactly the same settings. But after less then an hour on Fedora my eyes start aching. I start to suspect backlight frequency or something else, because first that one can notice is higher screen brightness and therefor colors are brighter also. I did the same xgamma settings, backlight level is also the same. Only thing is different, which I can see myself (and find myself) is PCI configuration. Latter I will send here picture of screen with different colors from opensuse and fedora, also video PCI memory dump _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
