I have to borrow a school laptop just to do proctored exams, because their “lockdown browser” doesn’t support Linux, and even if it did, it seems to do some things in kernel mode, so I don’t want it on my system.
Surprisingly, most classes at my university are entirely FOSS based, aside from that one piece of software, an obscure scientific program that only one assignment used, and MATLAB (which is easily replaced by GNU Octave.)
Debian! It’s stable, elegant, and doesn’t impede customization. I distro-hopped a lot over the years - some that I ended up disliking included KaOS (severely limited software repository), Clear Linux (only way to get ffmpeg was to compile it from source) and Fedora (very slow); most I liked, and just decided to move on at some point. But I kept coming back to Debian, and eventually got to a point where instead of trying a different distro when Debian broke, I would just reinstall Debian.
I’d be interested to try VanillaOS or another “immutable” distro at some point in the future. See if they’ve matured enough for my day-to-day use.
