I still have a Linux desktop machine but it doesn't get used a whole lot. Last time I tried Xubuntu on a laptop it still had problems with HiDPI and battery life. What's holding me back now is that I've switched to using a custom keyboard mapping and only made macOS/Windows layouts for it. If I can source a hardware USB mapper that would work, otherwise I have to do it twice again for Linux console and graphical.
