Synaptics touchpad two-finger scrolling



Hi list,

I had two-finger scrolling working with explicit lines in the xorg.conf.
Yet, trying to keep up and using hal instead I edited
/usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi and added
>         <merge key="input.x11_options.SHMConfig" type="string">On</merge>
>         <merge key="input.x11_options.VertTwoFingerScroll" type="string">1</merge>
>         <merge key="input.x11_options.HorizTwoFingerScroll" type="string">1</merge>
to the synaptics section. When checking lshal, it all seems to work
> udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input'
>   info.capabilities = {'input', 'input.touchpad'} (string list)
>   info.category = 'input'  (string)
>   info.parent = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port'  (string)
>   info.product = 'SynPS/2 Synaptics TouchPad'  (string)
>   info.subsystem = 'input'  (string)
>   info.udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input'  (string)
>   input.device = '/dev/input/event13'  (string)
>   input.originating_device = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port'  (string)
>   input.product = 'SynPS/2 Synaptics TouchPad'  (string)
>   input.x11_driver = 'synaptics'  (string)
>   input.x11_options.HorizTwoFingerScroll = '1'  (string)
>   input.x11_options.SHMConfig = 'On'  (string)
>   input.x11_options.VertTwoFingerScroll = '1'  (string)
>   linux.device_file = '/dev/input/event13'  (string)
>   linux.hotplug_type = 2  (0x2)  (int)
>   linux.subsystem = 'input'  (string)
>   linux.sysfs_path = '/sys/class/input/input13/event13'  (string)
yet in X it doesn't. Two-finger scrolling does not work, and trying
synclient of gsynaptics gives a message like
> Can't access shared memory area. SHMConfig disabled?

Does anybody know what's going on?
