[arch-general] LXDE on boot

Hi, I have installed openbox and lxde on a Raspberry Pi and configured to automatically start on boot. When I login (GUI), I get a blank screen with a cursor. Not the usual LXDE screen with panel at bottom. When I right click on mouse, I am given options--some of the applications will start such as xterm but others libreoffice don't. I don't know where the log files are? Is there anyone that can give me a helping hand. Thanks. John
