I installed Debian + KDE on my mom’s laptop. She hasn’t had a complaint since. How tech-savvy is she, you ask? I’m sitting with her right now, so out of politeness she put on headphones to watch her favorite soap opera. Mind you, the headphones weren’t plugged into the laptop. She was sitting there, headphones on her head, sound coming through the speakers, watching her soaps like this is how it’s meant to be done.
My dad doesn’t seem to know the difference between left and right clicking, but I installed Lubuntu to give new life to his old 2-in-1 laptop and he was pretty happy with it.
The only downside I’ve seen is that it doesn’t do “tablet mode” anymore, and the touchscreen is much less functional.
I’ve noticed KDE seems to handle some of the tablet functions better on my old shitty ASUS transformer flip (originally installed xfce mint)
