Back in 2018 or 2017 before grub2 was found insecure I had 7 distro's installed on my machine, 5 on the 10TB sata, 1 mx on usb stick and 2 on a usb3.0 passport. It felt good to have a choice and backup systems if one got so fucked it wouldn't boot.

So how is rEFInd or should I use the Suse boot menu that comes with the distro?

That's the thing about Manjaro is that you just choose proprietary and also during a kernel change to a new one Manjaro also updates the kernel headers and the nvidia drivers to the ones that work with that kernel.

I updated the drivers myself foolishly following the online guides to get smplayer with mvp to use graphic acceleration, spent 2 days then realized I fucked the entire system up and reinstalled Manjaro then went to the arch wiki and found Manjaro was using video acceleration with a simple terminal command and just set smplayer to VAPAU for the regular and hardware dropdowns and it ran great.

I made a huge good move though, I disconnected my 4k tv and put the old hdmi back on. Linux has got to get their shit together more on 4K since I couldn't even get Mint to boot the 4K tv while the advanced hardware version of MX booted up fine. Hit or miss with some hardware.
