pavucontrol probably the best option given your distro. Go with that.

Ain’t that the truth. But I love the workflow they offer. You don’t have to go looking for new windows. You can easily pin applications to virtual desktops and I prefer the multihead model they use over the one used by gnome or KDE.

Accidentally flashed a live image (PCBSD, IIRC) onto my 1TB external HDD instead of the thumb drive. Lost years of collected music and movies that night. I learned two things:

1. Don’t do this sort of thing in the middle of the night, when you’re tired and should be sleeping.
2. dd is nicknamed ‘disk destroyer’ for good reason.

You can either try to contact the seller and ask for the password or just erase the UEFI settings by shorting some jumper or something. There should be instructions how to do that for your specific model.

But I have to fight the stupid OS to give me useful information. I have to install 3^(rd) party stuff. By default you only get this useless error reporting tool. Even if you report an error your likely to never hear from anyone and the chance of the error being fixed is virtually nonexistent.

On Linux the necessary information is usually readily available. The worst offender in my experience is Steam itself. You can get logs from games fairy easily. But if Steam misbehaves things can get more complicated.

Sounds like a job for gamescope.

This might work.

If you’re ready to take a bit of a dive, take a look at NixOS. As a CI/CD guy it might be right up your alley.
It allows you to configure your entire system via a single, declarative config file, including any configurations for installed software. You could even develop the config in a VM and, once you’re happy with it, use the same for to configure your host machine.
Be warned, though: the wiki is nowhere near as good as the Arch wiki.

In the land of Mordor, where the shadows lie.

Judging by the name? Not so much.

I keep seeing ads

Well, there’s your problem. Block that shit!

Several good suggestions on here already. Home manager might be another approach.

Good ads? Love me a good oxymoron.

THIEF! It’s for the butterflies.

Occam’s razor struck again.

I’d say it’s the roof of a hut.

Aren’t most mods?

Definitely

So I assume CWM is short for crappy window manager? Or can your display only handle monochrome? /s

If I understand OP’s explanation correctly, they’re simply trying to make a, possibly selfhosted, copy of a GitHub repo.
In that case the misunderstanding would be in the role of the git command; it being simply a frontend to any git repo, not a client to GitHub.

The correct commands to achieve that would be

$ git init .
$ git remote add origin url
$ git remote add github url
$ git fetch github
$ git merge github/master 
$ git push -u origin master

There may be errors in the above code. I’m writing this from memory on my phone.
