It still depends on the hardware you have. If you have hardware that’s fully supported by the kernel version your distro is running, then it’s easy. But as soon as you add a piece of hardware that isn’t, there’s a good chance you need to spend a lot of time searching how to fix it. Buying a new mouse and all of a sudden not having sleep work is not a power user problem IMO.
You might try a Matrix group instead. Doesn’t require a phone number and supports more than 1000 users unlike Signal. Search is bad though unfortunately.
