Comment 28 for bug 870297

I confirm Alex's findings. Fully updated, no logging.

It worked briefly for me (see post #17), but after an update it stopped again. Its interesting that it works sometimes for some people but not others. Not sure if it might be helpful, but attached is a listing of all the installed versions of lightdm's dependencies. From:

$ for i in $(apt-cache depends lightdm | grep Depends | awk '{ print $2 }'); do dpkg -l | grep $i; done
