Hardware Profile 'Daemon'

atze · 2005-11-21 15:23:19

Hai everybody. I am a laptop user and at home i have a docking station. So i switch hardware often. Ive written a lillte deamon that detect wheter i am using a dockingstation or not. Depending the configuration it copies the configuration files. When stopping the daemon (actually it isn't really a daemon....) it writes back any changes you made in de configfile you are using.

#!/bin/bash

# source application-specific settings

# general config
. /etc/rc.conf
. /etc/rc.d/functions

case "$1" in
  start)
    stat_busy "Loading Hardware Profile"
    if [ -r /dev/hdc ]; then
        #Load Docking Configuration
        cp /etc/X11/xorg.crt /etc/X11/xorg.conf
    else
        #Load Non-Dock Configuration        
        cp /etc/X11/xorg.lcd /etc/X11/xorg.conf
    fi
    if [ $? -gt 0 ]; then
      stat_fail
    else
      stat_done
    fi
    ;;
  stop)
    stat_busy "Saving Hardware Profile"
    if [ -r /dev/hdc ]; then
        #Writing back possible changed configuration
        cp /etc/X11/xorg.conf /etc/X11/xorg.crt
    else
        #Writing back possible changed configuration
        cp /etc/X11/xorg.conf /etc/X11/xorg.lcd
    fi
    if [ $? -gt 0 ]; then
      stat_fail
    else
      stat_done
    fi
    ;;
  restart)
    $0 stop
    sleep 1
    $0 start
    ;;
  *)
    echo "usage: $0 {start|stop|restart}"  
esac

This code is quite simple actually it could be much more advanced but i have no expience in linux programming.
My laptop has no cd-drive, but the dockingstation has. so this line of code

 if [ -r /dev/hdc ]; then

checks if there is a cd drive.

Hmmm, very interesting - it's one of those brilliantly simple ideas.

One possible addition, just for fun:
if "xorg.lcd" or "xorg.crt" don't exist, you can run `hwd -X` to generate a config file.

Otherwise this is pretty cool - if I had a docking stating I'd use this 8)

Feel free to post it in the wiki too, just in case someone searches for "docking station" or something

thnx. Concerning the hwd -X thingy. I need some special configuration for my xorg.conf (en option for my videocard (Option "CrtOnly" "true") so hwd -X aint working. The wiki in a good idea, but i think it should be a bit more advanced. Maybe i should write something like the new network profile stuff.

This is a simple script, its a prime candidate for the Scripts section of the wiki:
http://wiki.archlinux.org/index.php/Category:Scripts

Others may improve it. I have no use for this either, but like phrakture, I think its a stroke of brilliance. :-)

Well, yeah hwd won't work for everyone, however it will work fine for some (my crt/lcd switch is pure hardware, so i need no special config to get it working) - and you can only have it run if the file doesn't exist. It was just a random idea.

well the hwd -X thing aint a bad idea, maybe it takes to much time. Actually this script should include more like (network/usb-drivers) mount point. It would maybe be even better if it would run before the bootsequence enters an runlevel so you can configure your rc.local to your current hardware profile.
