Re: [gdm-list] trouble with gdm

Hello Brian

thank you for your prompt answer.

it does not change anything

I do not think that my problem is related to this bug, indeed there is 
no crash of the server, the problem is just that I cannot connect the X 
terminal via xdmcp to the server

I downloaded the version GDM 2.19.1 and I installed it. Unfortunately, I 
have the same problem. By the way, by doing that, I have a new gdm (when 
I type gdm --version I got 2.19.1) but gdmlogin and gdmgreeter have not 
been upgraded by this new installation, is it worthwhile to upgrade them 
and if yes how?

I have the impression that my problem is may be not related to gdm. 
Indeed, using a linux PC (with Fedora Core 6) I can connect via xdmcp my 
server. Turning the debugging on, I got the following information:

part of /var/log/messages lappc-f020 : server, lappc-f021 Linux PC and 
lapxt144 : X Terminal

using the Linux PC to connect the server:

using the X Terminal to connect the server:

So in the two case, I got the same error message from gdmlogin (which 
seems not responsible of the problem) but mysteriously with the X 
Terminal the process stops ...........

Any ideas?

Thank you
