OK, I have a couple Dell Optiplex 980s that I am trying to get set up for a specialized application.  What I want to be able to do worked in Fedora 8 and earlier, but it has been broken since Fedora 9.  

PC1 I want to set up so it queries another (HP-UX) machine for a graphical CDE login to that system.  I have some success starting X manually using X -query <remotehost> -from <localhost>, but I have not been able to get the computer to boot up and display the CDE login.  

So far I have tried a fresh Fedora 15 install with no window managers installed, and after adding the remote host to /etc/hosts and /etc/X0.hosts, as well as generating an xorg.conf file using Xorg :0 -configure, I am able to get a CDE login using X -query <remotehost> 

PC2, I want to set up to act like a "dumb terminal", in other words, all I want it to do is show the blank root window and a cursor unless I am sending an application to it from the HP-UX machine.  I can get the blank root window that I am after using just X :0 -br -terminate, however I am not getting a cursor.

PC2 is actually PC1 right now as I am just trying to establish the procedure to get both done. 

I do not need any kind of display manager to be installed, though they do come in handy for some of the setup.

Installation was a standard vanilla "Graphical" installation with no window managers selected, and some of the development options selected. Kernel is 2.6.38.6-26.rc1.fc15.x86_64

The X11 application that these PCs will be running requires 8 bit color depth and a resolution of 1280x1024.
