OK. If I look at a backup from before the upgrade, there is a .dmrc file
last updated on 2012-05-30 that contains:

[Desktop]
Layout=gb       extd
Language=en_GB.UTF-8

Session=LXDE


If I look at the currently running system, there is a .dmrc file last
updated at 14:18 that says:

[Desktop]
Layout=gb       extd
Language=en_GB.UTF-8

Session=ubuntu


Note that this is after I have switched back to lxdm, rebooted, logged
into my lxde session and then logged out again.

So it looks to me (although I don't know what should be in a .dmrc file)
that lxde did create such a file properly, but it hasn't been upgraded
properly and may still be wrong?

Sorry, I don't know what a debconf default is.
