synaptics driver configuration in xorg.conf file

Sapfeer · 12-30-2009, 08:16 AM

I'm trying to configure my Synaptics touchpad via xorg.conf file, but it doesn't work... Here is my settings:

Code:

Section "InputDevice"
  Identifier  "SynPS/2 Synaptics TouchPad"
  Driver    "synaptics"
  Option    "Device" "/dev/input/event9"
  Option    "SendCoreEvents"
  Option    "Protocol"          "auto-dev"
  Option    "SHMConfig"          "true" 
  Option    "LeftEdge"          "1700"  
  Option    "RightEdge"          "5300"  
  Option    "TopEdge"          "1700"  
  Option    "BottomEdge"        "4200"  
  Option    "FingerLow"          "25"    
  Option    "FingerHigh"        "30"    
  Option    "MaxTapTime"        "180"  
  Option    "VertEdgeScroll"      "true"  
  Option    "HorizEdgeScroll"      "true"  
  Option    "CornerCoasting"      "true"  
  Option    "CoastingSpeed"      "0.30"  
  Option    "CircularScrolling"    "true"  
  Option    "CircScrollTrigger"    "8"    
  Option    "VertScrollDelta"      "100"  
  Option    "HorizScrollDelta"    "100"  
  Option    "MinSpeed"          "0.10"  
  Option    "MaxSpeed"          "0.60"  
  Option    "AccelFactor"        "0.0020"    
  Option    "VertTwoFingerScroll"  "true"  
  Option    "HorizTwoFingerScroll"  "true"  
  Option    "TapButton1"        "1"
  Option    "TapButton2"        "2"
  Option    "TapButton3"        "3"
EndSection

and here is configuration options from lshal command:

Code:

udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port_logicaldev_input'
  info.capabilities = {'input', 'input.touchpad'} (string list)
  info.category = 'input'  (string)
  info.parent = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port'  (string)
  info.product = 'SynPS/2 Synaptics TouchPad'  (string)
  info.subsystem = 'input'  (string)
  info.udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port_logicaldev_input'  (string)
  input.device = '/dev/input/event9'  (string)
  input.originating_device = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port'  (string)
  input.product = 'SynPS/2 Synaptics TouchPad'  (string)
  input.x11_driver = 'synaptics'  (string)
  linux.device_file = '/dev/input/event9'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/devices/platform/i8042/serio4/input/input9/event9'  (string)

and here is output of /proc/bus/input/devices file:

Code:

I: Bus=0011 Vendor=0002 Product=0007 Version=a5b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input9
U: Uniq=
H: Handlers=mouse1 event9 
B: EV=b
B: KEY=420 70000 0 0 0 0
B: ABS=11000003

I can't find out why settings, I put in xorg.conf don't apply to synaptics driver after reboot. I can add such settings in one of the hal configuration files, but I want to know why does my present configuration doesn't work...

Which distro is this? I had some Ubuntu issues of this nature and ended up finding that xorg.conf was empty/depreciated. AFAIR my answers came in the .hal files like you say, but I'm not sure if this was Ubuntu specific. My memory is not good but it rings a bell.

Many distros now use hal fdi files for this purpose.

On Arch and Gentoo, the fdi files live in /etc/hal/fdi/policy/

on my system, my synaptics fdi file looks like:

/etc/hal/fdi/policy/11-x11-synaptics.fdi

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>

Now there you go - I've learned something :-)

Thanks all for your answers!

I'm using Ubuntu Netbook Remix 9.10.

I have .fdi file in my hal policy directory too, but I just want to want, why don't settings in xorg.conf file apply to synaptics driver.

I suppose it is just because such settings are controlled by hal and not by X server... So, anyway, I can make my stuff work in other way.

Thanks a lot for your answers
