Oh, that’s helpful. Thank you for sharing that!

Turns out this was my goof. I was trying to set up auto-login on my user account. In doing so, I set it to automatically log in to Plasma (X11) instead of Plasma (Wayland). Odd that the default option in that dropdown is not the one you’re currently using, but 🤷‍♂️.

What I’m now trying to figure out is why I can’t set auto-login for Plasma (Wayland). The Apply button is disabled. 🤔

Thanks to everyone who shared ideas.

HDMI switcher is an interesting idea. Will it do more than just forward on the EDID? (Hope I have that right. 😅) Will it sorta translate it and push out its own EDID?

The cable is one of the two cables that previously completed the chain between the display and computer. Could it still be a problem in spite of that?

The monitor definitely is. Like I said, it was working when connected through the soundbar. It seems to be that it isn’t reporting capabilities the same way the soundbar did when connected directly to the computer.

For anyone who happens to find this later, putting it in ~/.xprofile did not work for me, so I’ll still with the other solution I posted here for now.

Ah, OK. I’ll give this a shot. I found a solution (posted in the comments), but I don’t love it because it depends on a sleep and isn’t deterministic. Thanks!

I found a solution that seems to be working. Forgot where I saw this, or I’d give credit. Maybe StackOverflow?

Anyway, the solution was to write a separate shell script for my keymaps with a sleep 2 at the top. The, I run it as a startup application with this command: /bin/bash -c "sh /home/me/.keymaps.sh"

Apparently, the desktop environment must be loaded in order for the keymaps to take, so having it in my profile was running the command too early.

Hmm. I don’t seem to have that file, so I guess that means I’m not using gdm? I haven’t changed the login manager, so it’s whatever comes out of the box with current Pop_os.

aside from leaving them behind

When I saw this, I thought it sounded really cool! That is, until I remembered that I literally never touch my Windows machine except for gaming, so, unless I’m going to try to play two games at once (spoiler: I’m not), I will unfortunately never have a use for this. 😅
