Yes. There are a number of True Type font servers for the X Window System. One of them is xfsft. Its home page is http://www.dcs.ed.ac.uk/home/jec/programs/xfsft/. There are also instructions for configuration.
People have reported success with other True Type font servers. There are links from the xfsft Home Page to them as well.
You can also compile True Type Font support into your X server directly. Again, refer to the xfsft Home Page for details.
