Do you really mean XDMCP, or just X?  XDMCP is for running a remote
desktop -- ie, a whole window-managed session -- while X itself is used
for displaying the individual windows.

If you're running X on your local Linux box, all you have to do is ssh
to the Solaris box and run the remote command, if you just want a single
app.  Do not adjust the DISPLAY variable, do not give -display
arguments, do not pass go.  It should "just work," unless you've
disabled X forwarding in either the ssh client or server.  If so, check
for the appropriate options -- it should be obvious.

For Windows clients, they'll need an X server of some sort installed. 
The best/most common ones are non-free; I don't have any experience with
the free ones.
