In theory when you do the login at another session, and then logout,
it'll save your previous session.
Maybe lightdm is confused and not getting the previous session name
from your user.
Try this to enable Unity-2d, for example (as root):
rm -f /home/linaro/.dmrc
rm -rf /var/cache/lightdm
rm -rf /var/lib/AccountsService/users
dbus_user_path=`dbus-send --system --type=method_call --print-reply
--dest=org.freedesktop.Accounts /org/freedesktop/Accounts
org.freedesktop.Accounts.FindUserByName string:$DEFAULT_USER | awk -F
"\"" {'print $2'}`
dbus-send --system --type=method_call --print-reply
--dest=org.freedesktop.Accounts ${dbus_user_path}
org.freedesktop.Accounts.User.SetXSession string:ubuntu-2d
And also remove the 'user-session' line from /etc/lightdm/lightdm.conf/
Reboot, and see if that works for you. Here's a way to check if you're
running unity-3d or 2d:

Yeah, that's a known issue and I'm still working on getting it fixed.
Hopefully this will be done in the next few days.
