As a Linux main, I don’t think it’s hard, but it’s also still not as good as Windows in some ways I find important. Fractional scaling for instance. I had a different resolutions multimonitor setup, and I definitely had more issues than on Windows. Also, now with two same reso monitors, I still have to switch to Windows to RDP into my work Win machine, because on Linux it’s so blurry due to difference in scaling, it hurts my eyes. Of course, I’m most likely in minority of a minority, but it’s still a thing.
Aww, I used to play this on my keyboard some 15 years ago. Fun times.
