I get the error “The mathematica fonts are not properly installed in your system.” What is wrong?
This means that your current X session cannot find the fonts needed to run Mathematica. This is usually due to a fontserver being down or not defined. You can almost always get it to work by running: xset fp+ tcp/fs1.math.ucdavis.edu:7100 xset fp+ tcp/fs2.math.ucdavis.edu:7100 xset fp+ tcp/fs3.math.ucdavis.edu:7100 xset fp rehash before starting mathematica.
