> I suspect that I have an outdated version of hotspot Linux profiler, but I can’t just go and download a fresh release from GitHub, because hotspot is a KDE app, and I use NixOS.
KDE (not to be confused with the Plasma desktop) is just a bunch of C++ libraries that can work on a variety of desktop environments and even OSes (though Hotspot being a perf report alternative is clearly meant for use with Linux).
I just went and downloaded the latest CI build from[0] and it ran just fine on my openSUSE Tumbleweed, running Xorg with Window Maker. I do have a bunch of KDE apps installed, like Kate (my currently preferred text editor), Dolphin (the file manager i use whenever i want thumbnails, usually for videos and images), Spectacle (for screenshots), Falkon (i use it as a "clean" browser to test out things), etc so i also do have the KDE lib
Read the rest
raries on my system, but that is just a `zypper install` away. Or an `apt-get install` or `pacman -S` or whatever package manager your distro uses, i've used a bunch of them and they all pretty much behaved the same. I'd expect Hotspot to be installable in the same way in any of them (and i'd expect the AppImage to have these libraries bundled in anyway so you probably wont need them[1]).
If there are issues with NixOS (i don't know, i haven't tried it) i think it might actually be a NixOS issue and not a KDE issue.
