I am running Lubuntu 16.04. This ships with openbox but I want to use ratposion.
The config file in ~/.config/lxsession/Lubuntu/desktop.conf specifies the window manager like so:
[Session]
windows_manager/command=openbox
This works perfectly. However, I wanted to replace openbox with x-window-manager so that I could use update-alternatives. When I do this, the window manager fails to start with the following error message: x-window-manager exit with this type of exit: 256. The same thing happens if I use the command ratpoison instead.
Why does only openbox work?
How can I get lxsession to start ratpoison? (preferably without adding it to the autostart file as that feels like a nasty [hack/workaround])
