Re: Nvidia GPU not recognized properly

Which tool are you using ?

If it gets the information from X/glxinfo it will be routed through xwayland which may report incorrectly.
(especially when using nvidia closed driver)

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Nvidia GPU not recognized properly

lspci -k
pacman -Qs nvidia # edit, lost a "Q"
eglinfo -B
nvidia-smi

[root@archlinux shobhit]# pacman -S nvidia
resolving dependencies...

Sorry, that was supposed to be "-Qs nvidia", but the nvidia driver is correctly installed and in use.

Looks like a KDE bug.
Generally don't pay too much attention to those neoscreenwhateverfetchinxi tools, they're not authoritative wrt what is and is not there or in use.

Edit:

qdbus6 org.kde.KWin /KWin supportInformation

I need to pay more attention to typos… it'll query the KDE window manager for some status report (incl. what hardware you're currently running on, nvidia or amd)
