Ubuntu – Why are some GUI fonts so small in Ubuntu 20.04? How to fix them

fontsguiMATLAB

I installed MATLAB 2020 via a university license and I noticed the fonts are extra small. Additionally, upon startup of Ubuntu a GUI opens up for my password which is also very small. I don't have that problem with other GUI windows I used in Ubuntu 20.04. What is the cause and how could I fix it?

Specially for MATLAB.

  • Following this suggestion by sarnold from Ubuntu IRC channel it is fixed now:

    >> s = settings;s.matlab.desktop.DisplayScaleFactor
    >> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 2
    

    It currently looks like this: enter image description here
