I am using Mythbuntu 14.04. Everything in Myth is working and the correct size. The problem is I selected the Nvidia driver during the install and now the text in any title bar window that I open is too small to read. Another post suggested switching to Nouveau driver and change the font size from 14 to 11. What is the simplest way to do that in Mythbuntu? I tried to reinstall but was not given the option to select a video driver in the re-install.
