Missing Adobe fonts

If you try to start up remote X11 application to display on your Ubuntu machine, and get errors complaining about missing fonts like:

-adobe-helvetica-medium-r-*-*-10-*-*-*-*-*-iso8859-1

here's how to fix it.

You have to install not just fonts, but also the font server. First, the font server:

sudo apt-get install xfs xfstt 

and the fonts:

sudo apt-get install t1-xfree86-nonfree ttf-xfree86-nonfree ttf-xfree86-nonfree-syriac xfonts-75dpi xfonts-100dpi

And then, restart X11 on your Ubuntu machine, or just reboot.
