[Public] Quadbuffer stereo is not supported on Linux. Alex From: amd-gfx <amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx>
On Behalf Of adblover I have no idea how to enable quadbuffer stereo (hdmi-3d) on linux for intel and amdgpu.
I tried using Option Stereo 12 with this result (WW) AMDGPU(0): Option "Stereo" is not used Hoping for solutions for both cards (intel arc,renoir)
thanks ----------------------------------------------
