Ok after a few months of cooking I will say RockOS is a disaster, I am very well aware we are still talking about RISC-V here and its rough but it does not need to be that rough. Tested the latest version from yesterday, audio still crackly and broken (internal audio and HDMI), getting a dedicated GPU to work still tedious and if it works pretty much everything OpenGL based segfaults, QT applications seem unstable.
Just for the heck of it I tested the ubuntu version intended for the HiFive Premier P550 because it uses the same SoC and wow it works and hell of a difference, audio is fine, dedicated GPU easier to get working, have yet to see applications crashing, most apps using OpenGL either work fine or do if you compile it your self.
Of course there is a few catches like you can’t clock the SoC up to 1.8 GHz, Kernel throws a few extra errors since it was made for the HiFive board and you have to undo a few things that make the fans go crazy but otherwise still a way better experience.
So yeah would be cool if you could use ubuntu and make the needed adjustments, would give everyone a better base to work and experiment from.
And for others who might wanna give it a try already:
