Changing font size

[ISnoem]

Hi. The entire UI is extremely small on my laptop. I have attempted to modify qt5ct but to no avail. Is it possible to adjust the font size and how?

You need to run the Qt6 version; but since you use Linux, it's all up to your distro.
I'd try using Manjaro for example - or whatever else that uses fresh packages so to speak.
