Please attach the output of drm_info (https://gitlab.freedesktop.org/emersion/drm_info) when the setting isn't available. Most likely you're experiencing https://gitlab.freedesktop.org/drm/amd/-/issues/2182 Created attachment 154659 [details]
Output of drm_info when Adaptive Sync option is missing
Here's with the setting missing for 1 of the 3 monitors I have. It should be connector 2, which has vrr_capable = 1. kscreen-doctor -o reports incapable, though.

Created attachment 154657 [details] Adaptive Sync setting in question SUMMARY This seems like two separate issues, but the second one needs the first one so I put them together: 1. Monitors need to be connected at boot in order to have the Adaptive Sync setting in Display Configuration 2. A monitor set to "Always" or "Automatically" use adaptive sync will be set to "Never" if kwin doesn't detect Adaptive Sync, meaning it has to be manually re-enabled after kwin can detect it again. STEPS TO REPRODUCE 1. Set Adaptive Sync to "Always" or "Automatic" for target monitor 2. Disconnect monitor 3. Reboot 4. After boot, connect monitor 5. Adaptive sync option will be missing 6. Reboot 7. Adaptive sync will be set to "Never" OBSERVED RESULT "Adaptive Sync" setting missing from Display Configuration, the gets set to "Never" EXPECTED RESULT Adaptive Sync can changed and the setting persists SOFTWARE/OS VERSIONS Kernel: Linux illode 6.0.12-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 08 Dec 2022 11:03:38 +0000 x86_64 GNU/Linux KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION * I have early KMS setup as described in the Arch Wiki instructions * GPU: 6900xt, open source drivers (amdgpu). * Both monitors are using Displayport, one has a Displayport <-> USB-C Adaptor * I didn't test x11
