I have very small text using nvidia drivers in my new Lubuntu 14.04 install. So small in fact that I couldn’t read anything!

I found an old thread from 2012 that helped point me in the right direction.

Click on Menu then Preferences and then “Customize Look and Feel”

Under the widget tab I changed the default font to a size of 24. After clicking apply it fixed the text in the windows but not the icon text.

I then clicked the font tab and changed the sub-pixel geometry from RGB to BGR. After saving it I have a nice looking screen again.

The problem is I haven’t figured out to keep the saved settings!

Here is that original thread that seemed to be the same issue yet no one was able to give an answer.
