[ubuntu] Ubuntu 12.04 - Thin Client takes too long time to display the login screen

Hello Everyone,

I have installed Ubuntu-12.04 LTS with LTSP and configured the dhcpd.conf file to boot . When I boot the Thin Client it detects the server and then starts the process of loading the login page, but this process takes too long (around 20 - 30 mins).

But once the login screen is displayed and useame and password is provided it immediately load the desktop and working with application is quick and smooth.

How can I reduce the time of loading the login page. I have existing Ubuntu 10.10 server implemented and the thin client boots very quickly (within 10 -15 Secs)

Thanks in advance,

Prasad
