[plug] XDMCP and GDM

[Tim White]

I believe that the best way to access another computer remotely and 
graphically is through XDMCP. I have an old computer that I wish to use 
as an Xterminal for my main computer so that my little sister can use it 
while I use it (seeing as it is normally wasting 90% of the CPU.
I am running Debian/Stable on the 'client' and Debian/Testing on the 
'server.' The client is running gdm=2.2.5.5-2 and the server is running 
gdm=2.6.0.4-1. This means that the client hasn't got the new themeable 
gdm and so I can't find out how to start the XDMCP chooser. I have 
enabled XDMCP on both machines and can connect from the server to the 
client but not the other way due to me not being able to start the XDMCP 
chooser. If I login and then run gdmchooser when I select a client it 
exits without connecting.

Also how does XDMCP work? I understand that it runs all the applications 
on the server but displays them on the client using the clients 
hardware. So does this mean that it also uses the clients X config? And 
if so should that mean glx (OpenGL) apps should work if the hardware 
supports it and the drivers are installed?

Thanks
