https://peppermintos.com/Proprietary nvidia graphics drivers now installed automatically if “Install third party drivers/software” is selected as part of the installation routine, this includes automatic configuration of nvidia optimus setups up to the nvidia-390 drivers. If you intend to install the later 396/410/415/418/430 drivers from the ‘Proprietary GPU Drivers’ PPA it would probably be best not to select this option during install and add them manually post-install.
That is assuming that the USB iso actually booted up to a LiveSession.You may have something no one has tackled yet. Try everything until something works, I guess.
Does this sound like it may help: https://linuxconfig.org/how-to-install-nvidia-drivers-on-linux-mint
They have a forum too: https://forum.peppermintos.com/
My Dell has an NVIDIA GTX 1050 card.my ASUS have NVIDIA GTX 1060 card,
the info above does not reference that, but I will try it anyway.
The Mageia installation media worked for me because it contains most of the proprietary drivers.I suggest to boot with the paramater nouveau.modeset=0. It disables the NVIDIA graphics adapter, which most probably needs the proprietary NVIDIA drivers.
