Niri + Noctalia on my diehard Lenovo 440S. Colour scheme is Nord. Fun fact, in my install, I don't have a graphical login screen and instead, I boot into CLI, login at CLI, and then call up Niri. Does not affect performance, I can suspend my computer, and I'm not sure if it is a bug, but after a couple of hours of the computer being suspended, it lights up and hibernates itself. I'm not going to try fix it, I think its cool.
