you could add another layer of swap in between ram and disk by using zram. as it compresses swap in ram with a very fast compressing algorithm it effectively expands the ram size

btop makes the dedicated gpu turn on, wasting energy and disrupting its power saving. yes, this can not be disabled in btop, so it happily shows no load on the gpu. gee, thanks.

Floppinux anyone?

Long time ago I had a 3.5" HD floppy disk Linux with graphical user interface and ethernet and some programs on it. But 64 bit and the increased kernel size probably make this difficult nowadays.
