Thanks Jeff, yes, SB was the culprit – which is unfortunate as I want to have it enabled. Will search for a way to sign the drivers and load them in Kinoite.

Now DRI_PRIME=1 lspci -n -n -k | grep -A 2 -e VGA -e 3D prints:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] [redacted] (rev a1)
        Subsystem: Lenovo Device [redacted]
        Kernel driver in use: nvidia

05:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne [Radeon Vega Series / Radeon Vega Mobile Series] [redacted] (rev c5)
        Subsystem: Lenovo Device [redacted]
        Kernel driver in use: amdgpu

which is great.

I still can’t get apps to actually use the discrete GPU. On GNOME there was a [Run with discrete GPU] option by right-clicking. KDE doesn’t seem to have such.
