Unable to read any information text running packet tracer in Kubuntu. Can't see the settings to try to change it either (I ran it on windows and was still unable to find a setting to change)
you might be missing a library file. How did you install PT ? Have a look at the link below...
I installed with a different "guide" online before. I started over and followed that one, but the same issue persists. I went through the table at the end of his article and tried individual packages, but no change. Any other thoughts?
I ran across this problem a while ago. My workaround for this is if I'm gonna use packet tracer, I'll change the COLORS not the theme to Breeze-Light so the font would be black not white since the color i was on was Aritim-Dark which has the font set as white.
Hope this helps for you as well!
