Synaptics and hal

I tried to configure the touchpad on my laptop (Sony Vaio VGN-SR21M) using synaptics. The procedure described in the wiki with hotplugging disabled works: I simply pasted the Section "InputDevice" example configuration in xorg.conf, modified the Section "ServerLayout" and Section "Module" as described and it worked smoothly. But when I tried to apply the configuration for hotplugging using hal it didn't work. This is my /etc/hal/fdi/policy/11-x11-synaptics.fdi:

This one works for me.... You may have to change left edge, right edge etc .... use synclient to get those values

Re: Synaptics and hal

When I try to launc synclient, eg. synclient -h, I obtain a message like 'Can't access shared memory area. SHMConfig disabled?'. Maybe I have to start this SHMConfig service? Even if this is the case, how can  I do it?

Re: Synaptics and hal

Check the output of 'lshal', it is probably loading the evdev driver instead of the synaptics driver.  If it is loading evdev it means its not matching the first line in the fdi:

<match key="info.capabilities" contains="input.touchpad">

You should be able to find the corect input from the lshal output.  For example you might need to change to:

<match key="info.capabilities" contains="input.mouse">

Re: Synaptics and hal

This is the touchpad section of lshal:

udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX1_port_logicaldev_input'
  info.capabilities = {'input', 'input.touchpad'} (string list)
  info.category = 'input'  (string)
  info.parent = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX1_port'  (string)
  info.product = 'SynPS/2 Synaptics TouchPad'  (string)
  info.subsystem = 'input'  (string)
  info.udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX1_port_logicaldev_input'  (string)
  input.device = '/dev/input/event8'  (string)
  input.originating_device = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX1_port'  (string)
  input.product = 'SynPS/2 Synaptics TouchPad'  (string)
  input.x11_driver = 'synaptics'  (string)
  input.x11_options.AccelFactor = '0.00150'  (string)
  input.x11_options.BottomEdge = '4200'  (string)
  input.x11_options.Device = '/dev/input/psaux'  (string)
  input.x11_options.FingerHigh = '30'  (string)
  input.x11_options.FingerLow = '25'  (string)
  input.x11_options.HorizEdgeScroll = '1'  (string)
  input.x11_options.HorizTwoFingerScroll = '1'  (string)
  input.x11_options.LeftEdge = '1700'  (string)
  input.x11_options.MaxSpeed = '0.70'  (string)
  input.x11_options.MaxTapMove = '220'  (string)
  input.x11_options.MaxTapTime = '180'  (string)
  input.x11_options.MinSpeed = '0.10'  (string)
  input.x11_options.RightEdge = '5300'  (string)
  input.x11_options.SHMConfig = 'on'  (string)
  input.x11_options.TapButton1 = '1'  (string)
  input.x11_options.TapButton2 = '2'  (string)
  input.x11_options.TapButton3 = '3'  (string)
  input.x11_options.TopEdge = '1700'  (string)
  input.x11_options.VertEdgeScroll = '1'  (string)
  input.x11_options.VertScrollDelta = '100'  (string)
  input.x11_options.VertTwoFingerScroll = '1'  (string)
  linux.device_file = '/dev/input/event8'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/class/input/input8/event8'  (string)

It seems that the options are correctly loaded, right? So maybe it's only matter of  finding the right settings?

Edit: weird enough, synclient says that "Can't access shared memory area. SHMConfig disabled?" even if SHMConfig = 'on'.

Re: Synaptics and hal

hey,

last week i bought exactly the same laptop and had also problems with
synaptics and hal.

thats my solution:

xorg.conf

Section "Device"
        Identifier  "Card0"
        Driver      "fglrx"
        VendorName  "ATI Technologies Inc"
        BoardName   "Radeon Mobility HD 3470"
        BusID       "PCI:1:0:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection

Section "DRI"
        Mode 0666
EndSection

Section "Extensions"
    Option      "Composite" "True"
EndSection

11-x11-synaptics.fdi:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.touchpad">
      <merge key="input.x11_driver" type="string">synaptics</merge>
      <merge key="input.x11_options.AlwaysCore" type="string">true</merge>
      <merge key="input.x11_options.VertEdgeScroll" type="string">true</merge>
      <merge key="input.x11_options.HorizEdgeScroll" type="string">true</merge>
      <merge key="input.x11_options.TapButton1" type="string">1</merge>
      <merge key="input.x11_options.TapButton2" type="string">2</merge>
      <merge key="input.x11_options.TapButton3" type="string">3</merge>
    </match>
  </device>
</deviceinfo>

quite vanilla, but now you can extend it with additionally values. ;-)

best wishes

Re: Synaptics and hal

Thank you, I found the problem: in the "ServerFlags" section there was a line Option "AutoAddDevices" "False", which prevented hal to correctly load the touchpad settings (I suppose...:|). Commenting out that line made everything OK.

BUT...

Now in my dual monitor configuration (laptop lcd + external monitor) the primary display is the external one, no matter how I modify xorg.conf. I suspect that hal, once the AutoAddDevices option was turned on, sets the primary display on its own, regardless of any setting in xorg.conf.
Can anyone confirm my suspects or tell me what's going on? And if it's really a hal issue, how can I configure it so that I can choose my primary screen?

Edit: I found a workaround. I configured the touchpad in xorg.conf and left the AutoAddDevice set to false (not a smart workaround but this works...:rolleyes:)
