Self-tutoring about Linux: the tutor mentions Lubuntu.
In my post from Feb 18, 2020, I mention Lubuntu. It has slim resource requirements.
I’m running it right now. This computer has 1GByte of ram and it’s a Pentium 4. The fact that its hard drive is 80GBytes might suggest its vintage.
Lubuntu comes with Firefox, a couple of office apps, a terminal, of course, an image viewer, and many other apps I’ve never used. I can’t recall its crashing, and by now I’ve used it for around 100 hours.
