Nice, I didn’t know about the all selector

for_window [app_id="^.*"] inhibit_idle fullscreen 

I don’t think downgrading the curl library is promising here. curlftpfs seems to be unmaintained. I recommend looking for alternatives or alternative workflows.

Fixed in curl, but not in a curlftpfs, apparently. Look at the comments on the accepted answer.

Seems to be a known bug: https://github.com/curl/curl/discussions/14299

Error setting curl:

That doesn’t seem like a complete error message to me. Is there any more information? Maybe with the -d (debug) flag?

It really depends on your approach to learning things. If you’re looking for a systematic approach, I really like No Starch Press books for that sort of thing: How Linux Works or Your Linux Toolbox (for a more playful approach).

But in the end there’s really no substitute for installing Debian on bare metal and tinkering with it. I would really recommend Debian, because it’s the archetype of how Linux systems have been working for the last 30 years or so. Arguably, this is currently changing, but come to grips with Debian before you dabble in more modern approaches to system management.

Same! This works really well.
