 Detecting Valid Server/Screen Is there a clean way to determine if a possible setting for the DISPLAY environment variable is valid? It's easy to check the output of ps for instances of X, but how can we find which display those X servers are serving? Thanks for any help! -- Chris Johnson cjohnson AT cs DOT utk DOT edu http://www.cs.utk.edu/~cjohnson  |
