I have a laptop with 4 GB of RAM that I’d like to use for occasional comic book reading. (It’s a touch screen 2-in-1 laptop that folds over into a tablet configuration.) I use Bazzite on my main PC and I love how low maintenance it is. Are there any immutable/atomic distros that featue XFCE, LXDE, or some other low RAM friendly desktop? Or, should I just layer XFCE or LXDE on top of UBlue Core or make my own image or something? Thanks!
Depending on your drivers, you could give Guix a go. It’s not for everyone; but it’s decent, solid, and I used to run it on a 32-bit machine with 3GB of RAM.
If you do require nonfree drivers, there are guides to set it up using Nonguix; but I don’t know how well that works (I am yet to try it).
