If you are using the X10R4 unix socket support for your display (ie, your DISPLAY environment variable is set to something like 'unix:0'), the xdemo program, written for some earlier X release, will give the "no such file or directory" error. If you set DISPLAY to be 'hostname:0', everything will work as the CLU X library expects. --Michael Halle Spatial Imaging Group MIT Media Lab
