NVidia/AMDGPU multigpu
Product: kwin
Version: unspecified

SUMMARY
I have a laptop with multi gpu, an integrated AMD Renoir and a dedicated NVidia
RTX. The external display HDMI and DisplayPort are connected through the
dedicated Nvidia gpu while the laptop display is connected to the integrated
AMD one.
With both Nvidia proprietary drivers and Nouveau, the external screens are not
detected.
Related to https://bugs.kde.org/show_bug.cgi?id=425586 but with Nvidia instead
of AMD dedicated GPU.
