After 1 week mucking around trying to fix my X11 installation, it is time to get help. Specifically, if/when my X11 works, what will it look like? When I click on X11.app, what will a working app do? Mine comes up, an icon stays in the dock for 10 secs, then it closes down. In the menu bar, I can see the X11 app for those 10 secs. But if I click on the Terminal, or xman, or xlogo under Applications in the X11 menu bar, nothing happens! I ask because I need X11 to get my Matlab installation working again. I am desperate because I have Matlab work piling up! Thanks. Also - any hints on how to get it working again will be gratefully received. Currently running 10.4.11 on an iMac, with an almost-empty 250 GB HD, 2GB memory.
