Synaptic touchpad, xorg and hal, and resuming

[Thomas Constans <thomas.constans@opendoor.fr>]

Hello,

Latest update on Sid brings hal support to xorg.

This means that your touchpad's configuration, that you have been
patiently setting up for hours  in /etc/X11/xorg.conf is no longer taken
into account.

You have 2 possibilities:

1 - Disable hal support by adding the following section
in /etc/X11/xorg.conf:


Section "ServerFlags"
   Option "AutoAddDevices" "False"
EndSection

2 - Export your xorg configuration in hal .fdi file format.

Create a file like /etc/hal/fdi/policy/apple.fdi with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
  <device>

    <match key="info.capabilities" contains="input.mouse">
      <merge key="input.x11_driver" type="string">evdev</merge>
    </match>

    <match key="info.capabilities" contains="input.touchpad">
      <match key="info.product" contains="appletouch">
        <merge key="input.x11_driver" type="string">synaptics</merge>
        <merge key="input.x11_options.SHMConfig" type="string">true</merge>
        <merge key="input.x11_options.LeftEdge" type="string">0</merge>
        <merge key="input.x11_options.RightEdge" type="string">900</merge>
        <merge key="input.x11_options.TopEdge" type="string">10</merge>

	<!-- as you can see, it is pretty easy to convert an xorg.conf appletouch option to an xml one. -->
      </match>
    </match>
  </device>

<!-- You can add a section for your keyboard configuration too: -->
  <device>
    <match key="info.capabilities" contains="input.keys">
      <merge key="input.x11_driver" type="string">evdev</merge>
      <merge key="input.x11_options.XkbRules" type="string">xorg</merge>
      <merge key="input.x11_options.XkbModel" type="string">pc105</merge>
      <merge key="input.x11_options.XkbLayout" type="string">fr</merge>
      <merge key="input.x11_options.XkbVariant" type="string">mac</merge>
      <merge key="input.x11_options.XkbOptions" type="strlist">lv3:lwin_switch</merge>
      <append key="input.x11_options.XkbOptions" type="strlist">compose:rwin</append>
    </match>
  </device>
</deviceinfo>

You will have to restart hal service and your x session to take this new configuration into account.


There remains one problem: Configuration is lost when laptop resume from suspend-to-ram.

I have to unload / reload appletouch and ohci-hcd modules to simulate an unplug / replug
and to get my configuration back.

So i have set up the following script in /etc/power/event.d/appletouch:

#! /bin/sh
case "$1" in
  resume)
     /sbin/modprobe -r ohci_hcd
     /sbin/modprobe -r appletouch
     /sbin/modprobe  appletouch
     /sbin/modprobe  ohci_hcd
  ;;
esac

but maybe there is a better fix ?

Hoping this will helps, 

Regards
