I went ahead and tried that, and it didn't work, I still get limited RGB by default, so I dug up the kernel sources and started poking around and if I'm reading them correctly, there is absolutely no way to get full RGB by default if you are using a mode that matches any of the standard CEA video modes. Is this really correct? Where's my kernel option to override this? :-). Can we add a user defined extension to EDID to change the default? (I have to override the EDID on the kernel command line anyway to fix the latest gnome stupidities). Is there a program I could include in the initramfs and change the setting really early? I certainly can't run xrandr then. I'm contemplating writing a program to hack the built in table of CEA video modes in drm.ko so the 1920x1080@60HZ won't match... _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
