Realtime kernel - no graphics

This is bad, really bad –

• The hardware in question is an ASUS TUF Gaming A15 Laptop –
• With an AMD Ryzen™ 7 4800H processor – with AMD Radeon™ Graphics – integrated.
• In addition, with a NVIDIA GeForce GTX 1650 Ti Mobile graphics card – as well and also …

Normally, one simply uses the “amdgpu” driver to pick up the GPU integrated with the CPU but, in this case, there’s also a NVIDIA GPU built into the box – and, the NVIDIA GPU is probably not removable …

Solution 1: Make absolutely sure that, the “amdgpu” driver is blacklisted – add “module_blacklist=amdgpu” to the Kernel’s boot command line.

Solution 2: Ensure that, when choosing an AMD CPU with integrated GPU that, no other graphic unit is present in the system.

Solution 3: If the systems graphics really has to be hardware supplied by NVIDIA, ensure that, the AMD Ryzen™ CPU doesn’t have an integrated graphics unit and –

*=2]ensure that the Mainboard doesn’t support integrated AMD graphics – dedicated hardware on the Mainboard which supports the GPU integrated with the CPU …

I have big doubts about that.
User simply needs to recompile drivers to use with rt variant of a kernel.

Why not using kernel-preempt? https://software.opensuse.org/search?utf8=✓&baseproject=ALL&q=kernel-preempt

But again, only for Leap 15.2: openSUSE Software

And now we have: openSUSE Software
Kernel from Community user: Welcome - openSUSE Build Service

Previously we cannot see stuff for Leap 15.3.
