<br><font size=2 face="sans-serif">The DISPLAY variable was not read in ~/.bashrc because this file began with a line</font>
<br><font size=2 face="sans-serif">telling to do nothing if the shell was not run interactively.</font>
<br>
<br><font size=2 face="sans-serif">As mpich uses rsh, a not interactive shell, the rest of the file was not read, and the DISPLAY variable not set.</font>
<br>
<br><font size=2 face="sans-serif">Just comment the line and everything works fine.</font>
