Title: Locking session leads to stale X server Status in Light Display Manager: Fix Committed Status in “lightdm” package in Ubuntu: Fix Committed Bug description: Choosing "Switch to different user" in Ubuntu gives you another login screen, which is very nice and useful. However after using that alternate session, lightdm keeps the X server and greeter for that alternate session open and running. Gdm, on the contrary, terminates the X server for the alternate session when you log out of it. This behaviour does make a difference when you run Ubuntu on a laptop on battery. Using the alternate login just once after boot (and ending the session again) initiates a constant cpu load of 1-2% (on my laptop). Doesn't sound much. But compared to "idle" without the second X server and greeter, this is an increase of about 75%. I admit that I didn't have the time to keep the laptop running idlely und doing some real battery measurements. But with a laptop on battery, you should use any possibility to save energy.
