I didn't have all your symptoms but it may be the same problem. The following is a quote of ms31003 from the MathGroup Archive 2001, written by J.P. Hinton. I too searched long and hard to find this. >>In determining the fonts available to the X server, the front end uses the >>standard Xlib function XListFonts().

Hinton >>User Interface Programmer paulh at wolfram.com >>Wolfram Research, Inc. >>Disclaimer: Opinions expressed herein are those of the author alone. You can determine the number of fonts on your system by issuing the following linux command line xlsfonts | grep ".*" -c xlsfonts lists the fonts, one per line, thus grep -c will count them. If you have a lot, this will several seconds. Compare the number of fonts counted with the number in the file Specific.tr referenced above by J.P. Hinton. If the number in Specific.tr is greater than your font count then you have a different problem otherwise update Specific.tr to have a slightly higher number then restart mathematica.
