modelsim ase 10.4d/quartus lite 16.0,15.1 on linux source font problem

I do not use any specific tools, my heuristics are pretty dumb, always analyze the directories for "suspicious" files, a very tedious method thoug :( plus a little bit of logic.

as of your rich distro question .. well Arch is the way to go. A pretty steep climb, but you're not a novice I suppose, so you'll manage.

I will try setting up infinality font packages today, as it replaces the entire font rendering system including fontconfig, they contain Helvetica as well, they also look pretty neat. Please specify your GNU/Linux distribution, to make things clear.
