We have been using thin clients with Ubuntu (first karmic, then lucid) 
for several years. Recently we had a need to move to fat clients. We 
installed trusty server and added ltsp-server (we have a separate DHCP 
server), and installed ubuntu-desktop in the client image and added 
gnome-session-flashback. Our client hardware has Atom D510 processors 
(dual core 1.66 GHz) and 2 GB RAM, which we have doubled for use as fat 
clients. The only issue is that on occasion the printer selection dialog 
box will only load the window decorations and hang for up to 2 minutes 
before filling in the list of printers. We have a CUPS server running on 
a separate 10.04 server, and have CUPS_SERVER pointed to that IP address 
in lts.conf. At first the delay happened every time we printed, but we 
added appropriate LDM_PRINTER_LIST and LDM_PRINTER_DEFAULT entries to 
lts.conf for each fat client and it seemed to help most of the time. We 
also tried changing BrowseRemoteProtocols to none in cups-browsed.conf 
in the client image. The delay can be seen in Firefox, LibreOffice and 
Evince, at seemingly random times. Any ideas what can be causing this?
