not all the issues were kernel related, I remember one time there was an update that defaulted the Legion Go's gamescope-session refresh rate values as 60,12060,120. Which broke literally every single game in gamescope-session until it was fixed to 60,14460,144 LGO screen is 144hz
but note, I also speak from the perspective of someone who's been helping a lot of other users for to troubleshoot. I maintain the legion-go-tricks repo, and Nobara was definitely more troublesome to support for everyday users.
He has done awesome work for the linux gaming community with ProtonGE, also Bazzite uses a bunch of stuff that he did. So yeah definitely great work there. But I like this Atomic Desktop thing
