Hello all I am a new linux user (Redhat 7) and I am trying to learn how to operate the system. I have a couple problems one the font size for all windows withing the OS are too small and even though I found a couple places to configure font size I can't find where to change the font size for the overall OS. Changing the resolution would achive my purpose I think. Its in 1024x768 but I don't know how to change it 
My second problem is installing programs does anyone know where I can find useful information on the basics of systems management on the net? BESIDES the FAQ I've read through it already.
Any help is greatly apprecited
