Any #Linux nerds out there who know about the inner-workings of #Wayland?
Having an issue with refresh rates.My work laptop runs #Ubuntu 22.04.5 LTS (not my choice), and it only seems to be able to detect my 165Hz monitor as 99.95Hz.
The thing is before I ran a dist-upgrade and it was running 20.04.6 LTS and using X11 it would run at the full refresh rate just fine, same monitor, same cable.
