Hello, I noticed the CTM support from X is no longer advertised with recent kernels. Card: Vega64 xf86-video-amdgpu: 22.0.0-1 With older kernels, xrandr reports CTM correctly. With the same X stack, simple rebooting on a more recent kernel, CTM is not advertised anymore. >$ uname -r >5.15.83-1-lts >$ xrandr --prop | grep -i ctm > CTM: 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 > CTM: 0 > CTM: 0 > CTM: 0 > CTM: 0 > CTM: 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 >$ > > -- Reboot to 6.1 -- > >$ uname -r >6.1.0-arch1-1 >$ xrandr --prop | grep -i ctm >$ I also have a custom config 6.0 kernel that shows no CTM so the break has happened between 5.15 and 6.0. I tried looking at commits in between and code changes in amdgpu but did not notice anything obvious.
