default session set to GNOME and fails. Should be Unity

[Jean-Baptiste Lallement]

Ubuntu Alternate i386 (20110802.1)

After a fresh LTSP installation the default session is set to GNOME and it fails with an error "Failed to load session 'gnome'" then the user is disconnected.

1. It should be unity as default
2. Gnome should not be proposed if it can not load

17:24 < stgraber> hello, not sure if someone mentioned it here already but ISO testing found bug 820372
17:24 < ubot2> Launchpad bug 820372 in ltsp "default session set to GNOME and fails. Should be Unity" [High,Confirmed] https://launchpad.net/bugs/820372
17:24 < stgraber> which isn't an LTSP bug but a gnome-session one
17:24 < stgraber> LTSP calls /etc/X11/Xsession to start whatever is the default session (no parameter)
17:24 < stgraber> Xsession then starts gnome-session but without a --session= parameter which makes it fail
17:24 < stgraber> I think we had a fix in Natty to make it use a the right "default" session but that apparently got lost somewhere
17:25 < stgraber> was wondering what source package I should move that bug to?
17:25 < cyphermox> stgraber: what I would see was aside from the Ubuntu and Ubuntu 2D entries there was an extra GNOME one that shouldn't be there
17:26 < cyphermox> (outside of ltsp)
17:27 < stgraber> with Edubuntu we have gnome-session-fallback installed so apparently gnome-session starts the fallback session then (instead of unity-3d =>
                  unity-2d => gnome-session-fallback) but on regular Ubuntu, it just fails
17:28 < cyphermox> mmkay, so which case is failing now?
17:29 < stgraber> calling "/etc/X11/Xsession" with no parameter doesn't start the default session on regular Ubuntu
17:29 < stgraber> the same thing on Edubuntu works but starts the session fallback instead of unity (which is wrong too)
17:31 < stgraber> simply calling "/etc/X11/Xsession" from a terminal on your system should reproduce the issue
17:32 < seb128> stgraber, can you check with didrocks when he's around?
17:32 < seb128> stgraber, or better assigned the bug to canonical desktop team
17:32 < seb128> we will sort it
17:41 < stgraber> seb128: ok, will do

yeah, this code changed between natty and oneiric, it's not the same issue: I tried to be better a citizen and have --session=ubuntu now. So we default to pure GNOME otherwise.

I'll set the "no parameter" to ubuntu as a distro-patch.

This bug was fixed in the package gnome-session - 3.1.3-0ubuntu7

---------------
gnome-session (3.1.3-0ubuntu7) oneiric; urgency=low

  * add debian/gnome-session-common.gsettings-override:
    - set ubuntu as the default session if nothing is provided

bad, you must also update /usr/share/xsessions/gnome-shell.desktop to pass --session=gnome otherwise you get a crappy compiz with nothing but nautilus when you asked for gnome-shell.
