I just tried Xming and I was able to do a full graphical login on a
Debian Lenny server, but not my K12LTSP 5.0EL server. On the K12
server, I got my GDM screen and logged in, but it gave me a black screen
with a mouse pointer. (not very useful). I was able to run a single
remote application (I tested with gedit) on both servers using Xming.
Here's what I did.
I installed Xming, Xming-fonts, and then Xming-mesa (I don't know what
the difference is between Xming and Xming-mesa, but it didn't work until
I installed Xming-mesa. I suspect you're supposed to install either
Xming or Xming-mesa, but I'm not sure). I accepted all the defaults.
Start, Programs, Xming, XLaunch
To run a single application:
"Multiple Windows", "Start a Program", enter a program name (maybe gedit
or firefox or something), "Using PuTTY", enter your server name, user
name, and password, then finish.
-or-
To run GDM and full desktop login:
"One window" or "Fullscreen", "Open session via XDMCP", enter your
server name
