I started in the Graphics/Display forum because I thought I was having an issue with the display driver. History of work done here: Graphics Forum Question And Data.

I have updated all Manjaro components to the latest and greatest. Bios is old. But have not found an update anywhere. Nor had a response in the forums for information.
Nothing tried was successful in resolving a no display on boot. Brief synopsis: System boots. Screen displays a “no signal” message after a few seconds. Then goes into sleep mode. This happens when I use GRUB_CMDLINE_LINUX_DEFAULT="quiet splash udev.log_priority=3"
If I add nomodeset monitor has output.
I am new to Linux. But somewhat experienced in computer troubleshooting. I kept digging around the internet. Spent some period of time using journalctl to speed read logs. Noticed a pattern. Log in “random” places repeated

I ended up using: sudo journalctl -o short-precise -k -b -2 -r
to get me the last 50 lines of a boot where I had a no signal scenario. The error was one of the last things before I force power down the computer. If I understand correctly, this error indicated an inability to find/initialize the HDMI port.
