You are. Reformat and install the first hardware compatible distro you find on https://distro.moe/ right now. Don’t think too much about it, just do it! /s, probably?
If checking out a different distro sounds interesting and/or fun then you should. If not, then don’t. Whatever way you Linux is the correct way for you.
I came here to make a similar comment. In KDE just use… I could swear it was ctrl+alt+arrow key but a quick search tells me it’s meta+arrow key (currently on my phone) to tile windows if I want. Quarter or half sceen tiling works for me so I’m content with that. OP didn’t specifically say dynamic tiling so perhaps one of these methods will be sufficient for OP?
I’ll check out that tiling feature mentioned above, I wasn’t aware of it and am curious!
