I have also tried to blacklist the nouveau drivers as given here:
https://forums.developer.nvidia.com/t/nvidia-issue/177273/24
Now the system boots but NVIDIA drivers are not loaded (nvidia-smi gives an error) and the display is stuck at 640x480 resolution.
Again I ran the nvidia-bug-report as root and I will attach the report later.
When I look into this bug report too the nouveau drivers seem still loaded. How is this possible ?
Is there something else I have to do like in GRUB: The NVIDIA probe routine was not called for 1 device(s) · Issue #1 · probonopd/system · GitHub ?
