KDE + Wayland uses llvmpipe instead of Nvidia GPU

I have install KDE Plasma with Wayland and the nvidia open modules, but when I open the system settings it shows this:

How can I fix this?

Re: KDE + Wayland uses llvmpipe instead of Nvidia GPU

this is the normal stiuation, need not a fix.
wayland use egl architecture and KDE or lowlevel stack just pick only one available driver or best supported one automatically.
i dont read archwiki so refer there look at 'wayland' and 'EGL' titles then look for nvidia in that titles.

This is hardly "normal"…

Re: KDE + Wayland uses llvmpipe instead of Nvidia GPU

Looks very much like the rest of the system has no problem identifying the nvidia GPU & driver - what's the output of 

prime-run glxinfo -B # prime-run from nvidia-prime package

There's a good chance that's just a bug in that dialog.

Re: KDE + Wayland uses llvmpipe instead of Nvidia GPU

There's a good chance that's just a bug in that dialog.

Nothing you posted indicates that the nvidia GPU would not be available for prime offloading - perhaps a glitch in plasma/wayland (you can check whether the dialog does better at detecting your HW on an X11 session) - you might want to file a bug at bugs.kde.org and take away from this that all the info aggregators (also inxi, screen/neo/whateverfetch) are not reliable or authoritative sources to analyze your system wink
