It’s a temporary thing and it’s likly Kent will just spend the time too continue development and prepare patches for next cycle instead. The ambition is to take it out of Experimental status sometime in the next year so there’s at least motivation to figure out these things. During the delay testers of this FS can still submit bug reports.
Yes I encountered that when I used Tumbleweed on my laptop, the solution was to run “sudo prime-select boot offload”. It set up my laptop to use iGPU for desktop environment and NV offload for gaming. I made it part of my update script. No idea why that wasn’t handled better.
But generally I’m done with rolling distros, I now use an Ubuntu derivative that still keeps kernel and mesa quite up to date, I enjoy a stable environment.
