I'm running all this 3.23.91 stuff (mutter+GS) and I can log in and use GS.
I still experience some sudden logouts (it will happen every time when I get no icons on the desktop at startup), but that was already the case in 3.23.90.
I run Nvidia 375.39 from Ubuntu official repository, but I mainly use Intel iGPU.
