Hello, just to add to Rob's remarks:
I have 455.23.04-1 from experimental installed since my last post, everything is stable, and clinfo and glxinfo report fully working OpenCL and GLX setups. Only thing I miss is a working nvidia-settings, as 450.66-1 is not working with those experimental packages, and there is no newer version of nvidia-settings in any release.
My other system runs Arch, and Arch already switched to nvidia 455 drivers with their 5.9 kernel, so there no comparable problem surfaced.
Is there any reason you made a new nvidia 450 release instead of propagating the already working nvidia 455 experimental builds?
Greetings Heinz
