https://bugs.freedesktop.org/show_bug.cgi?id=83226 --- Comment #30 from Pitscho --- Sorry, I have no time atm to teach myself on how to compile the kernel and add patches and so on (I like to do as soon as I have time). So I've just installed Kernel 4.1.6 as *.deb on my Xubuntu machine. A very big thank you for your efforts. Tvrgb works for me when I enable it via xrandr. My grey levels are way better now and my Chroomecast image isn't greyish anylonger, because I can use limitedRGB on every device. The ycbcr modes give me shifted colors (greyish pink). PS: First I acceidentally enabled tvrgb for the wrong output (HDMI-1 (nothing connected) instead of HDMI-0) This froze my lightdm session and I had to reboot. sudo restart lightdm did not work. -- You are receiving this mail because: You are the assignee for the bug.
