From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

how to create scripts that run on random stuff (lemmy.ml)

so I want to create two scripts

first one that basically runs "systemctl suspend" when the lid is closed basically the default behavior doesn't work for some reason and running systemctl suspend always works so yeah you get the idea
since I have made the headsets aka the jack output and the default speakers each their respective sink (that's what I actually want (to have the power to put whatever I want in each sink using qpwgraph ) ) but that power comes at the cost of not switching between those respective two sinks so I just want to change I guess either the wireplumber config file or create a systemd service that runs when the jack port is plugged or unplugged

but I am lost in both questions to be honest and wireplumber is a mystery lol - sorry for being a noob if that matters

For your first point you'd probably want to investigate why your system doesn't suspend or what exactly is going on. You could check logind.conf, specifically the HandleLidSwitch* keys. Otherwise, your lid switch should have a corresponding /dev/input/ event that you could maybe listen to or something.
I can't offer much input on your second point. I think unplugging the audio jack should probably trigger a udev event that you could write a rule for. No idea about wireplumber though.

thanks for the idea it actually got me to find something so I am going to use "acpi_listen" I guess its a deamon for acpi the funny thing is closing the lid counts as "button/wlan WLAN 00000080 00000000 K" so I am positive linux or the kernel thinks that closing the lid is pressing the wiki toggle button (that's the current behaviour btw) so I guess the next step is to just find out how can I make the kernel think that closing the lid is actually closing the lid lol

anyway thanks for the help stranger
