How to use matchbox-window-manager with web browser?

Question

I'm having trouble with running uzbl browser under matchbox-window-manager on a raspberry pi. I'm using it with a 22' lcd screen to display some info (temperatures, graphs, VPS server stats...).

What I actually did is: Set up the raspberry pi to start X at startup (raspi-config). Created /home/pi/.xsession with the following contents:

kiosk-browser &
exec matchbox-window-manager -use_cursor no -use_titlebar no

kiosk-browser contents:

#! /bin/bash

while true
do
    if [ $(pidof -x uzbl-core | wc -l | tr -s "\n") -eq 0 ]
    then
        uzbl -u http://localhost/ -n kiosk &
    fi


    memFree=$(grep MemFree /proc/meminfo | awk '{print $2}')

    if [ $memFree -lt 30000 ]
    then
        echo 'reload_ign_cache' > /tmp/uzbl_fifo_kiosk
    fi


    sleep 20
done

So you now see what I'm trying to achieve. I'm updating some divs contents and images using jQuery, and didn't find a better way not to freeze the pi after consuming all available RAM, as each browser I tested does this (after some significant ammount of time).

The problem I'm having with this setup is it sometimes doesn't reload the browser properly, but freezes instead. Sometimes with a black screen (as when the pi starts), sometimes it's white screen (uzbl loading html), and sometimes even sooner, before dismissing the old html contents.

So basically what I'm trying to ask is, is this setup ok? Is this how it's done, or am I missing something? :)

THANK YOU!

Thank you all for helping me! I managed to probably solved this with just using lightdm (no other window manager).

Contents of kiosk-browser now:

while true
do
    if [ $(pidof -x uzbl-core | wc -l | tr -s "\n") -eq 0 ]
    then
        uzbl -u http://localhost/ -n kiosk -g 1366x768+0+0 &
    fi


    memFree=$(grep MemFree /proc/meminfo | awk '{print $2}')

    if [ $memFree -lt 30000 ]
    then
        echo 'reload_ign_cache' > /tmp/uzbl_fifo_kiosk
    fi


    sleep 10
done

Then I edited /etc/lightdm/lightdm.conf to log in as 'pi' and use the 'kiosk' session:

autologin-user=pi
autologin-session=kiosk

And created a file @ /usr/share/xsessions/kiosk.desktop:

[Desktop Entry]
Encoding=UTF-8
Name=kiosk
Type=Application
Exec=kiosk-browser

to start kiosk-browser when lightdm starts...
