Plot Config menu doesn't come up

In some cases customers were having problems starting the Plot Configuration menu from our Qckvu product.


Warning: Cannot convert string "-adobe-helvetica-bold-r-normal--34-341-72-72-p-0-iso8859-1" to type FontStruct
_X11TransSocketINETConnect: Can't get address for sx13
/vendor/i686/artwork/default/bin/xpltcfg: can't open display, exiting...

We found out that this error can happen when the DISPLAY variable is not set properly due to name resolution issues.

What we recommend is
set the $DISPLAY to ip_address:0 instead of hostname:0.
It probably cannot resolve the ip address of the machine due to name resolution issues with DNS or the /etc/hosts file.
