Setup CLFSWM

This article is based on my previous post "Setup Common Lisp Environment". Please read that first if you have not.
For me, one way to learn a new language is to use it frequently. To learn common lisp, I try to use clfswm (Common Lisp FullScreen Window Manager: http://common-lisp.net/project/clfswm/) in one of my machine. It is written/configured with common lisp.
I use quick lisp to install clfswm as follow:

* (qlsetup)
* (ql:quickload "clfswm")

Gnome is my primary desktop now, to continue use gnome applications in clfswm, I add a .xsession file as follow in my home directory:

#!/bin/bash

# log for debugging, quite useful if you make some mistake in your configuration
exec &> $HOME/.clfswm.log

gnome-settings-daemon &
eval `gnome-keyring-daemon`
nm-applet &
# or some other panel application, I mainly use it for systray support
fbpanel &
# some applications I used everyday, so I start up them along with login
gnome-terminal &
emacs &

# to setup background, you can select other applications for it too
feh --bg-center /usr/share/wallpapers/joy/contents/images/1366x768.png
exec sbcl --noinform --no-userinit --no-sysinit --eval "(require :asdf)" \
    --eval "(require :clfswm)" --eval "(clfswm:main)" --quit

To adapt clfswm to my habit (mostly based on gnome), I customized clfswm a little via .clfswmrc. I changed fbpanel a little for clfswm too. Details will be in following posts.
In fact, I still have several issues with my clfswm, this prevents me to use it as my primary window manager in my laptop.

• Sometimes modal dialog will make a frame "frozen" after covered by other window, that is, no reaction for hot key. I need to click another frame and back to the frame to switch to the modal dialog.
• I do not find real full screen support. Some software need real full screen to display a full screen "edge menu" (such as virtualbox). Or maybe software thinks it is in full screen mode, I just can not activate the "edge menu".
