My cousin gave an old acer switch that she wasn´t using, its extremely underpowered with 2gb of ram, an old atom and 32 gigs of storage. I tried ubuntu with gnome because thats what i use on my main laptop and while it has amazing touchscreen support it barely runs. I then decided to try lxqt and it runs great but the touch support is really bad. Does anyone know a DE with a good balance between performance and usability? xfce doesnt really seem to have good touch support either and tbh i really dislike it.
Can confirm from personal experience, KDE Plasma is arguably the best choice.
I used it on a tiny Surface Go without issue, and I use it with a touch pen display.
You can easily rearrange the UI so things are positioned where your hands are.
Also, it’s the only setup I found where I could rely on virtual keyboards alone, after installing OnBoard.
I also tried Gnome and PopOS, and Plasma came out on top.
