Bug Description

 gdm-guest-session (0.17) maverick-proposed; urgency=low
 .
   * Makefile:
     - symlink the restricted session env variable to une one to workaround
       gconfd in maverick, seeing GDMSESSION=une-guest-restricted instead of
       "une", like other any other process in the guest session (LP: #657371)

test case:
1. Install this version
2. start ubuntu netbook edition session in gdm (you should have unity appearing)
3. under the session indicator menu, choose "guest session"
4. check that you are indeed logged in a guest ubuntu netbook session
5. check that you cannot access anything in /home/

debdiff attached
-------------

 netbook-meta (2.035) maverick-proposed; urgency=low
 .
   * Refreshed dependencies
   * Added gdm-guest-session to netbook-recommends (LP: #657371)

test case:
if you don't have gdm-guest-session, on upgrade, you should get it. Check after upgrading to that version that you get a "guest session" entry in the session indicator after a session restart.

-------------

It's simply not seeded in the netbook metapackage for final.

In addition, there is something wrong for launching it (I fixed that in lucid a while ago):
The env variable aren't set correctly, and so unity doesn't start in this guest session. Investigation for a fix in a SRU.

after some investigation, it seems that gconfd is launched under GDMSESSION=une-guest-restricted instead under "une" value like in lucid. Consequently, all the session tweak to launch the right parameters doesn't hence.

What is weird is that there is still my changes for lucid:
/usr/share/gdm/guest-session/Xsession:
export GDMSESSION="${GDMSESSION%%-guest-restricted}"
and all other guest user session process have GDMSESSION=une environment variable. All, but gconfd!

I tried to revert to lucid gdm, gconf, gdm-guest-session and old unity, but didn't get it working. I think something changed in the order.

So, the current workaround is to symlink where gconf is reading his value from the une guest restricted session to une ones. We will make more deep changes to Natty.

Wrt. installing gdm-guest-session by default, is this a regression from lucid? Otherwise this would be a new feature, why is it SRU worthy?

Didier Roche (didrocks) wrote :

It wasn't in lucid as well. Yesterday, I was pinged by rick and robbie about not having the guest session in UNE. To be honest, I was really thinking we had it by default (as I patched it in lucid to get it working in UNE) as I install ubuntu-netbook and ubuntu-desktop metapackge on my netbook. It's only once looking at the seed that I remarked it wasn't the case. I think it's still a valuable feature by default, especially with people wanting to try unity in a guest session to share the love :)

SRU verification for gdm-guest-session Maverick:
With gdm-guest-session 0.17 from -proposed installed, logged in as guest I can access data in /home of another user.
This behaviour is the same with 0.16, so this is not a regression introduced by 0.17 but a failed anyway.

Marking as verification-failed

false alarm, the apparmor profile was not loaded. After loading it or rebooting the system version 0.17 works as expected.

SRU verification for Maverick:
I have reproduced the problem with ubuntu-netbook 2.034 in maverick and have verified that the version of ubuntu-netbook 2.035 in -proposed fixes the issue. I've verified that g-g-s was not installed and is installed as a recommend of ubuntu-netbook 2.035.
