My Edubuntu 11.04 as a ltsp server works very well. I use Atom/ION as a
thin client. Works very well with Nouveau. But.

How I force easily thin client/user use only "Classic Gnome desktop (no
effects)" Well, I do not like "Unity 2D" ;-).

You know, there is only Gnome, nothing else.

# update-alternatives --config x-session-manager
There is only one alternative in link group x-session-manager:
/usr/bin/gnome-session
Nothing to configure.

Can I force "Classic Gnome desktop (no effects)" in users .xsession? If
not, where?

Best Regards Asmo Koskinen.

Friend of mine Mikael showed me a solution.

1.

lts.conf

[default]
LDM_XSESSION=classic-gnome-session

2.

/usr/local/bin/classic-gnome-session (chmod +x)

#!/bin/sh
/usr/bin/gnome-session --session=classic-gnome

3.

Edubuntu AMD64 11.04 is in KVM.
HP Mini 2133 boots with forced desktop, just typing user/passwd in LDM,
session can be default in LDM, no need to change.


Both Unity and Compiz are there.

Without these two scripts I got in HP Mini 2133 Unity 2D desktop what I
do not want.

I believe that this does exactly what your solution does, but just more concise:

in /var/lib/tftpboot/ltsp/i386/lts.conf:
[default]
LDM_XSESSION="gnome-session --session=classic-gnome"


Now, all of my users have ubuntu-classic as the default session.
