I am running Linux Lite 1.0.6. I seem to be having some trouble with xfwm4 (the default window manager), and would like to try a couple of others. I have downloaded and installed lxde and Fluxbox, with the expectation that I would be given a choice on the login screen as to which wm I want to use, but that doesn't seem to be happening. There is no option on the login screen for selecting a window manager. There are sub-menus under Settings in the main menu labeled "Window Manager" and "Window Manager Tweaks," but neither seems to do anything when I select them. Am I missing something obvious? How do I activate these other window managers? Thanks for any help provided. I would have posted what Display Manager I'm using, but I confess I don't know how to find that.

Update: I have found that, by turning on "Launch Gnome (or KDE) Services on Startup," the Window Manager and Window Manager Tweaks menu choices do become funtional. However, they only provide configuration parameters for the current session. Also I have confirmed that there are indeed scripts for LXDE and Fluxbox in the /usr/share/xsessions directory; I just need to figure out how to get the logon manager to look for them.

is linux lite running xfce4 as desktop environment?
you have to ask yourself if you want to replace the whole DE with something much more barebone, or if you really just want to replace xfwm4. i have done this once - replace xfwm4 with openbox, still running xfce4 DE - it works nicely once set up properly. which is done in some files under /etc/X11 or /etc/xdg iirc.
some xml files telling xfce what apps to start at login.
come to think of it, i think there's even a gui for "advanced settings" hidden somewhere...
if you succeed you can still log into your default session, but use openbox instead of xfwm4.

Thanks, ondoho. I don't have the process completely automated yet, but I have found that I can change to openbox with a Terminal command, which is a great workaround for now. Thanks again.
