We have an environment of X servers running on DOS. To get an X session started I have written a daemon for the Unix system(s) that gets kicked from DOS. It then starts up xdm with the command: xdm -nodaemon -server "xxxx:0 transient blotto" Everything works fine as long as we actually start the session, terminate the session gracefully and (I think) wait a little while to give xdm a chance to reset the server. If the entire session cycle is not run then there is an xdm out there that never seems to give up. Actually, there is an xdm that forks another xdm that tries to connect to the server. This child does give up, but then the parent xdm just forks again. Is there some way to make it give up? Also, does xdm really need so many processes around?

Support for transient displays exists only because of xdmshell. The majority of your problems probably arise because this transient support is not complete enough in the distributed xdm. This lack of a completed design will cause xdm to restart the session whenever it fails unexpectedly (as this is the desired behaviour for local permanent sessions). The eventual solution is XDMCP which will (probably) appear with the next release of the system. Read the file "protocol" included with the xdm sources for an overview of the intended functionality. Please be aware that the actual protocol in that document will share little with any eventual standard. For now, I suggest the obvious work-around, request that users of this (obviously inadaquate) system make sure the session terminates normally before turning off the display.
