I normally login to my server and someone remotely X's in from a slow workstation (in fact, it's happening right now!).
I don't know what is happening but AFAIK: 1. you can keep the /etc/X11/xdm/Xservers as it is (automagically runs a display) and you can also let prefdm/kdm startup on your server machine (when I mean server, I mean the powerful network server machine, not the X-way of thinking which is reversed). However, if you want to use startx on your server, you must disable the line in /etc/X11/xdm/Xservers but still allow prefdm/kdm to run. 2. to start the x session from the workstation, type X -query <server>....actually just in case, type X :1 -query server. 3. your problems may be related to having displays already started and startx fails because it tries to open up display :0 (symptom is usually "Cannot open display")...this is why you need to comment out /etc/X11/xdm/Xservers if you want to use startx. Also, simply telinit 3; telinit 5 is usually not enough (it doesn't kill enough processes). You need to clean up the "mess" by telinit 3; killall kdm; killall X; telinit 5. This is probably causing you most of the trouble. 4. Ok, here is the way to debug: On your server: a) Change all those lines I told you to touch (including commenting out the line in /etc/X11/xdm/Xservers) on your server machine. b) telinit 3 c) killall X d) killall kdm e) kdm At this point, kdm would read your new settings and hopefully it will not pop up a new display (i.e. it will _not_ bring up a login screen). f) type startx... Does it work (it should)? Then, on your thinclient/workstation: a) telinit 3 b) killall X c) killall kdm d) X :1 -query <server> Does it bring up the login screen of your server (it should)? If all this works, kill all your X displays and kdms on both computers. Then telinit 5 on both (again, kdm should _not_ bring up a login screen on the server). Try startx on your server (does it work?). Then try the X :1 -query <server> (does that work?). If all this works, all you need to do is comment out the line in /etc/X11/xdm/Xservers for your workstation also so that you don't have to type "X :1" instead of X. btw, what is Xnest?
