default session of ubuntu-2d doesn't work

[Kyle Nitzsche]

I created a defaults pkg using ubuntu-defaults-builder.

I set the desktop/default-session.txt first and only non-comment line to:
ubuntu-2d

In the running system with this installed, there is a file named:
/usr/share/xsessions/ubuntu-2d.desktop

However:
 * the greeter does not selecte "Ubuntu 2D" as the default (Ubuntu is selected)
 * for the one user created during oem-config and for any new users created at run time
 * and if the default is used, the session is indeed unity (not unity-2d, which is installed)

Apparently lightdm now creates an /etc/lightdm/lightdm.conf by default. When I wrote that part, it wasn't, so I thought I'd rather not change an already existing config. But it seems we need to do that now.

Do you need this as an oneiric SRU, or will precise be enough?

Actually I need something working so I can set ubunty-2d as default this week. I am thinking of diverting /usr/share/xsessions/ubuntu.desktop and adding /usr/share/xsessions/ubuntu-3d.desktop (with ubuntu-contents) because I notice that by default, greeter seems to select the lowest desktop file in alphabetical order. Thus, ubuntu-2d wins and is default,

Uploaded to oneiric final queue now, I think we can still squeeze this in.

This bug was fixed in the package ubuntu-defaults-builder - 0.23

---------------
ubuntu-defaults-builder (0.23) oneiric; urgency=low

  * debhelper-scripts/postinst-ubuntu-defaults-desktop-session: Use
    /usr/lib/lightdm/lightdm-set-defaults to also change the default session
    if /etc/lightdm/lightdm.conf already exists (which is the case in oneiric
    final). (LP: #869546)

@Kyle -- there :-) That should avoid having to do hacks like diverting the session files.

[Kyle Nitzsche (knitzsche)]

@Martin: it worked, hacks remove. thanks.
