After traveling out of town for about a week, I returned home to boot up and find updates available. Applying them, unfortunately without much attention to logged messages, I restarted the system as instructed, only to boot into an entirely black screen. Since then, I’ve read everything I can find about the problem. I’m afraid I’ve tried so many troubleshooting and fix actions in a desperate attempt to get my system back that I’ve lost track, and I’ve almost certainly made the problem worse.
I have experience with technology dating back to the early 1980s, mostly IBM mainframe (DOS/VSE and VM/CMS), Windows, and Chrome OS, with only passing brushes with Unix- and Linux-based systems. Seeking to replace my desktop setup, I was persuaded to give Manjaro with KDE Plasma a try. I’m wondering now if I’ve made a horrible mistake.
Anyway, here’s my inxi output (hoping I’ve formatted correctly):

On attempting to boot normally, I see the following error messages on the console before it stalls and turns black:
error: no server is specified.
error: no suitable video mode found.
error: no video mode activated.
error: symbol 'grub_efi_set_variable_to_string' not found.
Is my system beyond redemption at this point? I’m now entirely at a loss as to how to diagnose what’s wrong and what steps might help toward recovery. Any suggestions?
