Bug Description
After loging in into the XCFE environment, I open a terminal and perform a top.
If I sort the processes by decreasing resident memory, I see that lightdm requires 32MB of memory, that is more than X !
Since lightdm just sleeps after login in, I think it is wasting memory.
Could it possibly load/unload features dynamically as gdm already did (many small processes which were launched when a feature was required) ?

Yes this is what I get as well. I was shocked to see MATE using 230M with nothing running. It was quite a bit less in Precise.
htop shows lightdm using 31M. Switching to slim and lxdm saved memory, but they are not as useful.
