I have tried out Gnome, KDE, Lxqt and Xfce on a regular desktop and all of them feel nice. I haven’t tried many DE’s on a laptop.
Are there any particular DE’s you like on a laptop, because of things like power consumption and efficiency that would not come normally into consideration for a desktop?
Tiling window managers like i3 are imho nice for laptops, since they do not waste any space and can be easily controlled via keyboard. Takes a while to get used to them, however.
i3wm on my laptop, light on resources, keyboard-driven saves screen estate (no window decorations), and picom makes it easy on the eyes (rounded corners, shadows). If you prefer wayland, sway (and swayfx) is the way.
I agree with this! I run i3 for all my builds and it’s great!
