When adding a font with your package manager (in my case, pacman), even if it's fixed, it won't appear in the list of fonts you might use in Konsole unless you logout-login. Reproducible: Always Steps to Reproduce: 1. install a fixed font (envy-code-r, inconsolata-g, monofur...) 2. goto Konsole Appearance settings Actual Results: The new font is unavailable Expected Results: The new font is available
You do not need to log out, just make sure Konsole process no longer runs, i.e. close all its windows. Applications (or even fontconfig itself) cache the list of fonts, because it is an expensive operation to look for all of them. With many other settings (e.g. language change etc.) it is quite normal that they are only applied when the application is restarted, and I would not consider it a bug.
