I'm hoping if I can figure out these nVidia error messages I can get it working properly:

History
I used prime-select nvidia to turn on nVidia. Then it booted to black login screen. I updated grub kernel parameters with nomodeset:
- The external display (HDMI 1920x1080) disappeared
- The desktop icons piled up on top of each other at the bottom of display
- The brightness control slider disappeared
