@areinisc added another thing at the start of my commands, worth giving a shot

Hi hachre, figured you might like some closure and I wanted to thank you again
for your help. I re-installed the whole os from live media a couple more
times, playing with different things. Eventually I decided/figured out
something similar to the following:

• manjaro tries to pull in the appropriate drivers for your system with mhwd
• my system is a tower with an asus mobo, intel i7 cpu, and gtx 1080 gpu
• mhwd decided that I wanted the "video-hybrid-intel-nvidia-bumblebee" driver
• adventured down the bumblebee/optimus/prime rabbit hole
• most people explain that bumblebee is for laptops only
• ArchWiki says that bumblebee can work on desktops too
• maybe I should just chuck bumblebee out the window
• mhwd -i pci video-nvidia after uninstalling that bumblebee driver
• rebooted
• and it failed
• on a whim at 2am I thought, "Maybe I should plug my HDMI cord into the gpu hdmi port instead of the one from the mobo." I did that and rebooted and it worked.

So, I am very interested in learning more about hybrid graphics solutions for desktop pcs
and more in general about what I was doing wrong and what I should have been doing instead, and whether I ended up with a "correct" solution or just one that "happens to work"
