Lubuntu Cosmic LXQt session asks for Window Manager

There are two sessions: OpenBox and LXQt. The latter provides a fairly unfriendly default OpenBox environment with no panel. At least you can right click your way to things. The LXQt session, however, requires you to pick a window manager. If you select OpenBox, it loads an environment that also has no panel, but its right click menu is just the standard one with PCManFM which is not extremely helpful. That said, unless you know your OpenBox keybindings, you're kind of stuck.
