Setup used in Greek Schools

[Alkis Georgopoulos]

Hi David, sorry but I don't have the time to write an extensive how-to 
(I already maintain one in Greek :)), so I'll only mention a few tips:

* We're still using Ubuntu 12.04.x because we have extremely varying 
hardware, so some schools need the old Xorg and kernel from 12.04.1, 
while other schools need the new ones from 12.04.5, and there were even 
schools that needed a new kernel and an old Xorg.
That's due to unfortunate regressions of the newer software.
We also have an issue with Ubuntu 14.04 keyboard layout not working 
properly in Unity/Gnome/Gnome-flashback, and another one with 
gnome-keyring making thousand of files with SSHFS (LP: #1321922).
These 3 issues maybe don't affect many of the users here, so you can 
probably just go ahead and use 14.04.

* I recently committed in LTSP a few fixes for Unity, so if you'll be 
using the Greek schools PPA, you can select any desktop environment that 
you want.
Gnome-flashback and Mate are also good choices, especially if you also 
have thin clients where 3D doesn't work over the network and software 
rendering is used instead, making Unity extremely slow.

* About the flow control issue (gigabit server, 100mbps clients) we've 
recently updated our /etc/network/if-up.d/sch-scripts script so that it 
works in all cases, so you can just follow this how-to I've written:
https://help.ubuntu.com/community/UbuntuLTSP/FlowControl

* Firefox is a good browser. Sometimes a newer flash is needed though, 
so it's nice to also have google-chrome installed, which has flash 
version 18 instead of 11.

* And of course I always suggest to people to follow the ltsp-pnp page, 
as it makes installation and maintenance much easier:

Cheers,
Alkis
