Of course, nothing is "resolved" by removing package that is part of distribution. It just helps to diagnose it.

Hi everybody,
If you have a problem in Leap 42.3 installing your Nvidia driver you must remove the "drm-knp-default" package.
Oh! So, how does one compile KMP that depends on another KMP, which itself overrides in-tree kernel driver?
Depends, and it's note quite easy.
We somehow need to pickup correct symbol versions, otherwise we get
[ 202.462673] nvidia_drm: disagrees about version of symbol drm_atomic_get_connector_state [ 202.462674] nvidia_drm: Unknown symbol drm_atomic_get_connector_state (err -22) [ 202.462679] nvidia_drm: disagrees about version of symbol drm_gem_prime_export [ 202.462680] nvidia_drm: Unknown symbol drm_gem_prime_export (err -22)
This case is unfortunately very hard to resolve. The changes in the drm are so large, thus we can't keep symbols to be compatible. (It's possible to hack so that symbols appear same, but it doesn't help unless the call functionality is aligned as well -- i.e. you may change the struct fields identical with two kernel versions, but if the usage of the struct is different, it shall crash.) It'd be possible to export include/drm/*.h and include/uapi/drm/*.h as another *-devel package, but then still you'd need to hack nvidia build system to refer to these include files as well. So it can't work as is, either. The simplest and probably best option is to uninstall the DRM stack update if you're using Nvidia driver, after all...
