Ubuntu
gdm package

When starting a remote xdmcp session on GDM, it doesn't login.

Asked by David Hill

Hi guys,

  I have this weird issue where I've successfully configured GDM/X.org to provide XDMCP service... The only problem is that when I click the "Log In" button, the window turns grey and I need to kill the remote session because it doesn't login ... it never displays the desktop.

Now, what's weird is that if I attach strace to /usr/lib/gdm/gdm-simple-greeter to investigate, the login works and I can successfully see the desktop.

Any ideas on how to solve this?

Thanks,

When I don't attach strace, gdm-simple-greeter becomes a zombie :

gdm 2406 4.0 0.0 0 0 ? Z 17:48 0:00 | \_ [gdm-simple-gree] <defunct>
