Arch is running pretty smooth. Even fractional scaling on Wayland works fine.
Noticed only some minor things:
- Wifi throughput seems too low: although connection reports >1 gig link, e.g. Steam only reaches ~160 mbps when using local file transfer via 1gig / 10gig LAN backbone
- Firefox seems to randomly pick iGPU / dGPU (may also depende on power power profile or if on battery / AC power, need to observe it more)
- VRR is not reported correctly. See [ANNOUNCEMENT] Adaptive Sync / Freesync / VRR not working - #3 by Matt_Hartley
- PPD profile switching required custom udev rules. I’m guessing these are already present on Ubuntu and Fedora ?
EDIT:
Regarding harware monitoring:
- lm_sensors did not detect any sensor, but using ACPI fallback mostly works for temperatures
- CPU fan is not reported in ACPI “sensor”
- dGPU Fanspeed is not reported by amdgpu correctly: it is always 0 rpm, even in games
