Thanks for taking the time to reply, that makes a lot of sense.
I haven’t switched to Wayland yet. It makes sense why xscreensaver wouldn’t work well with an entirely different window server. I was just surprised it was so difficult (for me at least) to use with modern window managers despite being relevant and mature, haha.
I tried Linux briefly in highschool (around the year 2000) before going back to Windows (I love video games). I switched about 2 years ago back to Linux (Debian). Your comment made me remember xscreensaver and I went and installed it again. The matrix screensaver is a huge throwback, I love it and I missed it.
But it was a pain to do this. I’m using KDE/Plasma on Debian, and I had to follow this process to get it done. My lock buttons built into KDE menus still don’t work despite replacing kscreenlocker_greet like the manpage recommends. I’m not sure it’s worth my time to try to figure out, since the page warns an update will revert this. I’m not going to remember how to fix it later. I choose to lock my computer with super+L so this isn’t a huge issue for me.
The process to use xscreensaver with gnome looks equally bad.
WHY is this so tough, though? Debian “just works” for me, so needing to fumble through this manpage feels pretty lame. The process looks similar on other distros, from a quick google. I’m not an IT person or a programmer, and this doesn’t feel very “linux” that it’s this way. Why would these window managers replace something that just works?
I suppose it does look a bit dated?
I think that suggestion about Matlab is silly, that’s so overkill.
But, in case you ever run out of graph paper, consider Desmos, I use it a lot because it’s simple:
