====== Remove the Shutdown Dialog Box ======

Some people find the shutdown dialog box annoying. You can change the behaviour so that hitting the power button turns off the EEE without the dialog box. This is for for easy mode only.

===== Easy Mode =====

  * Open a terminal (Ctrl+Alt+t) and type:

   sudo su
   cd /opt/xandros/bin
   mv shutdown_dialog shutdown_dialog.backup
   echo -e '#!/bin/bash\nsudo /sbin/fastshutdown.sh' > shutdown_dialog
   chmod +x shutdown_dialog
   exit

===== Undoing this =====

  * Open a terminal and type:

   sudo su
   cd /opt/xandros/bin
   mv shutdown_dialog.backup shutdown_dialog
   exit

===== How this works =====

Pressing the power button runs a script called /etc/acpi/powerbtn.sh// 
This script then calls the shutdown_dialog file. Initially this file is the annoying dialog box, but we have changed it to run a script called /sbin/fastshutdown.sh//
This script kills the processes and shuts down the EEE.

===== Alternative Options =====

If you would like an easier confirmation box, that asks "Are You Sure?", then (this assumes you have done the steps above):

  * sudo kwrite /opt/xandros/bin/shutdown_dialog
  * Edit the 2nd line to:

   sudo /sbin/fastshutdown.sh --ask

  * Save (Ctrl+s) and Exit (Ctrl+q)

The general consensus seems to be the fastshutdown.sh script is the best way to shut down. However, some people are happy with editing /etc/acpi/powerbtn.sh to just say:

   #!/bin/sh
   /bin/kill -SIGUSR2 1


===== Another Alternative - Two presses to shutdown =====

If you want the Standby / Restart / Shut Down options but don't want the hassle of the "Sure you want to proceed" dialog, add the following lines after the # comments in the /etc/acpi/powerbtn.sh script.
<code>if ps -Af | grep '[s]hutdown_dialog'
then
        killall shutdown_dialog
        sync
        /sbin/fastshutdown.sh
fi</code>
The first press of the power button will bring up the normal options, but a second press will shut down fully.
