Explanation for newbies: setuid is a special permission bit that makes an executable run with the permissions of its owner rather than the user executing it. This is often used to let a user run a specific program as root without having sudo access.
If this sounds like a security nightmare, that’s because it is.
In linux, setuid is slowly being phased out by Capabilities. An example of this is the ping command which used to need setuid in order to create raw sockets, but now just needs the cap_net_raw capability. More info: https://unix.stackexchange.com/questions/382771/why-does-ping-need-setuid-permission. Nevertheless, many linux distros still ship with setuid executables, for example passwd from the shadow-utils package.
You can modify the keybinds in software too. You would need to change your console keymap (TTY) and your desktop environment keybindings. Programmable keyboard is most likely easier though.
I played around with it and changed both to just use F1 = tty1 and so on, without requiring CTRL+ALT.
You can also create a custom keyboard layout in Linux. From what I have written down, here is how to do it (can’t double check because work computer).
I suspect this could be X11 only because it is X keyboard extension, pop_OS! didn’t adopt Wayland as early Ubuntu.
