I need to just start X with firefox without anything else but maybe a screensaver, my first atempt on disabling /etc/rcS.d/S70x11-common and adding startx firefox at the end (but before exit 0) on /etc/rc.local has result on a pretty black screen and blocked system.

Any clue on how to achive my goal?

Hi.

The way I usually do these things is install some minimal window manager like AEWM (http://www.red-bean.com/decklin/aewm/) and write a script to start whatever you need.

I created the following script for Chromium, but you should be able to adapt it for Firefox. It is called chromium.sh and resides in /root in this example.

Code:

#!/bin/bash

ARG=$1

if [ "$ARG" = "start" ]

then

       echo "  starting chromium..."

       echo $$ > /var/run/chromium.pid

       #run xinit in a loop to respawn the desktop if killed

       while [ -f "/var/run/chromium.pid" ]; do

               xinit /root/chromium.sh &> /dev/null

               sleep 1

       done

       rm -f /var/run/chromium.pid

else if [ "$ARG" = "stop" ]

       then

               rm -f /var/run/chromium.pid

               killall X

       else

               shift

               echo -e $$ > /var/run/chromium.pid

               #call chromium

               /usr/bin/chromium &

               #run aewm as window manager

               aewm -1 "aemenu --switch" -2 "aemenu --switch" -3 "aemenu --switch"

       fi

fi

Which you can then run from rc.local:

Code:

/root/chromium.sh start &

By the way, Chromium might be a better choice than Firefox since it appears to be a lot faster.

Johan.

Thanks for the reply , I selected firefox due the R-Kiosk plugin do what I was looking for and it's enough quick for may taste, but I take note on chromium

but something still doesn't work
I have desisntalled gdm ,
I have renamed /etc/rcS.d/S70x11-common to /etc/rcS.d/s70x11-common
and I try your aproach modifiying the script that way:
/root/kiosk.sh

Code:

#!/bin/bash

ARG=$1

if [ "$ARG" = "start" ]

then

       echo "  starting kiosk..."

       echo $$ > /var/run/kiosk.pid

       #run xinit in a loop to respawn the desktop if killed

       while [ -f "/var/run/kiosk.pid" ]; do

               xinit /root/kiosk.sh &> /dev/null

               sleep 1

       done

       rm -f /var/run/kiosk.pid

else if [ "$ARG" = "stop" ]

       then

               rm -f /var/run/kiosk.pid

               killall Xorg

       else

               shift

               echo -e $$ > /var/run/kiosk.pid

               #run gnome as window manager

               /usr/bin/gnome-wm &

	       sleep 1

               DISPLAY=:0.0 /usr/bin/firefox &

       fi

fi

and add
/root/kiosk.sh start &
at the end of /etc/rc.local (just before exit 0)

But the result is an endless loop of trying to start X,

I have even simplified the whole thing creating a script
like this
/root/kiosk2.sh

Code:

/usr/bin/gnome-wm &

DISPLAY=:0.0 /usr/bin/firefox 

and add to rc.local

Code:

xinit /root/kiosk2.sh &

with same result but of course in this case it just try once,

But the most curious of all this is that

running "xinit /root/kiosk2.sh &" from a terminal works! but it doesn't work form rc.local
What the &%&/( I'm missing?

here is the full copy of my rc.local

Code:

#!/bin/sh -e

#

# rc.local

#

# This script is executed at the end of each multiuser runlevel.

# Make sure that the script will "exit 0" on success or any other

# value on error.

#

# In order to enable or disable this script just change the execution

# bits.

#

# By default this script does nothing.

machine=$(grep "^Hardware" /proc/cpuinfo | sed 's/Hardware\s*:\s*//')

case "$machine" in

	"Genesi Efika MX (Smartbook)")

		board=efikasb

	;;

	"Genesi Efika MX (Smarttop)")

		board=efikamx

	;;

esac

if [ "${board}" = "efikamx" ]; then

	if [ -f /sys/class/graphics/fb0/audio ]; then

		modprobe snd-spdif

		modprobe snd-soc-imx-3stack-sgtl5000

	else

		modprobe snd-soc-imx-3stack-sgtl5000

		modprobe snd-spdif

	fi

else

	modprobe snd-soc-imx-3stack-sgtl5000

fi

su -

xinit /root/kiosk.sh &

exit 0

Hi.

Two things:

1) remove the & from "DISPLAY=:0.0 /usr/bin/firefox &"

2) in rc.local, put "/root/kiosk.sh start" instead of " xinit /root/kiosk.sh & " (make sure kiosk.sh is executable)

Just tried it quickly here on my netbook and it works.

Johan.
