On Quantal, tried the recommended work-around from:
https://wiki.ubuntu.com/CustomXSession
that is:
Create a new file /usr/share/xsessions/custom.desktop with:
[Desktop Entry]
Name=Xsession
Exec=/etc/X11/Xsession
This did allow me to select a different login session, which did, in fact run
my ~/.xsession
but, there is still something a bit off. It appears the lightdm is invoking:
/bin/sh /usr/sbin/lightdm-session /etc/X11/Xsession
Which means arg1 in the Xsession script is: /etc/X11/Xsession
This results in some parts of Xsession.d/ being run twice (probably not what we
want).
Also, it seemed like the lightdm / pam integration started:
gnome-keyring-daemon --daemonize --login
but nothing did the: eval `gnome-keyring-daemon --start`
- I can add this to my ~/.xsession
Also, Xsession started an ssh-agent (even though we have gnome-keyring-
daemon which does similar things).
If you don't put the gnome-keyring-daemon --start in your .xsession, the
gnome-keyring-daemon started earlier by pam will exit, leaving your environment
a bit messed up.

There are a number of bugs out there on the pam/gnome-keyring-daemon issues
with non gnome desktops:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653011
https://bugs.launchpad.net/fedora/+source/gnome-keyring/+bug/932177
Soooo, I ended up hacking in several more work-arounds to actually make things
work.
The work-around are a bit ugly and more involved than I want to capture here
and certainly well beyond what an average non-admin user could manage.
It seems a bit of design needed to integrate lightdm / Xsession. Perhaps this
bug should be split to indicate:
- custom.desktop file is missing
- bad arg1 on Xsession
- gnome-keyring-daemon not initialized (refer to other bugs)
I may try and capture some of my work around at
https://sites.google.com/site/i3windowmanager/ (let me know if you are
interested).
