So I just got a 144Hz Freesync monitor, and I’ve verified that the Freesync part is working fine with Win10. But it is not available under Fedora 28 according to this official AMD guideline: https://support.amd.com/en-us/kb-articles/pages/how-to-enable-amd-freesync-in-linux.aspx. Thinking that this might only apply to the AMDGPU-PRO driver, I looked for other ways to verify Freesync functionality including passing ‘amdgpu.dc=1’ to the kernel, but xrandr --prop still doesn’t return any Freesync info.
Anybody know how to turn Freesync on with the open source amdgpu driver? I’m pretty sure it’s available to AMDGPU-PRO users, but my distro (Fedora 28) isn’t supported by the closed source driver AFAIK.
