I am getting fuzzy output, unaligned characters, and jaggedy-edged characters. I'm using Computer Modern, or that's the idea anyway. The output looks slightly different on Preview, Acroread, and Ghostscript, but it looks bad on all of them. The results are the same whichever of Lyx's built-in methods of generating .pdf I use. Do I not have a font installed properly, perhaps?
install the latin modern fonts and then write into the preamble \usepackage{lmodern}% this is the best choice
or install the cm-super fonts
or write into the preamble \usepackage{mathptmx} \usepackage[scaled=0.92]{helvet}
