Cannot boot LXDE

[urur]

Hi,
I installed LXDE and want to choose each boot whether to run Gnome or LXDE. However Gnome gets started automatically without me being able to choose.
Are there any config files I have to edit?
Thanks.

From System -> Administration -> Login screen, disable the auto-login option. Then you will be able to chose.

You can chose now, if you select "logout" and then you can "login" with a different session.
