Synaptics touchpad in Slackware 12.2 on HP G60

Mig21 · 02-06-2009, 03:12 PM

Hi

I have an HP G60 and I'm trying to get the fancy (e.g. scrolling) touchpad features to work, but I'm having trouble with that.

I tried using the following in xorg.conf:

Code:

Section "InputDevice"
    Identifier     "Mouse0"
    Driver         "synaptics" # instead of "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

but when X starts, it says no supported synaptics devices found and falling back to psaux.

Does anyone have any suggestions what else I could try?

Thanks in advance.

Comment out the line...

Code:

options psmouse proto=imps

in /etc/modprobe.d/psmouse

I have also found that

Code:

options psmouse proto=auto

works on my Slackware 12.1 on one system, but it is not a 'supported' option as far as I can tell.

After making this change do

Code:

modprobe -r psmouse
modprobe psmouse

to reload the module.

AstroGeek's suggestion (have ONLY a single line in /etc/modprobe.d/psmouse ):

Code:

options psmouse proto=any

worked for me on an Hp Pavilion zd7015.

In addition to entering 'stuff' for the TouchPad in the InputDevice Section, be sure to add an InputDevice line for the Synaptics TouchPad to the "ServerLayout" Section:

Code:

        InputDevice    "Synaptics TouchPad"  "AlwaysCore"

Just after the entry for mouse0 ( InputDevice "Mouse0" "CorePointer" ) ( see below )

Also, very important for the synaptics driver is that you need to add the infamous "SHMConfig" "on" to the "InputDevice" section for the mouse. Otherwise synclient and syndaemon wont work ...

I am still struggling with tuning the TouchPad (it tends to jump around a lot when I'm typing (syndaemon helps))
but I am trying to tune the sensitivity via synclient (vary cool app).

Anyhow, here are the sections I modified in /etc/X11/xorg.conf for the Synaptics Touchpad on my Dad's zd7015:

Code:

#
# Add an InputDevice for the "Synaptics TouchPad" at the very top of xorg.conf
#
Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Synaptics TouchPad"  "AlwaysCore"
EndSection

Then leave mouse0 the way it was.

Code:

#
# leave this in case he plugs in a PS/2 mouse
#
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5 6 7"
EndSection

Finally here is my as-yet unfinished Synaptics Entry (still tuning it). Note that the Identifier matches the "InputDevice" above.

Code:

 
#
# kjh added a Synaptics TouchPad section
#
Section "InputDevice"
        Identifier      "Synaptics TouchPad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mouse1"
        Option          "Protocol"              "auto-dev"
        Option          "Sensitivity"           "0.8"
        Option          "HorizScrollDelta"      "0"
        Option          "LeftEdge"              "1700"
        Option          "RightEdge"             "5300"
        Option          "TopEdge"               "1700"
        Option          "BottomEdge"            "4200"
        Option          "FingerLow"             "30"
        Option          "FingerHigh"            "80"
        Option          "MaxTapTime"            "180"
        Option          "MaxTapMove"            "220"
        Option          "VertScrollDelta"       "100"
        Option          "MinSpeed"              "0.09"
        Option          "MaxSpeed"              "0.18"
        Option          "AccelFactor"           "0.0015"
        Option          "SHMConfig"             "on"
EndSection

P.S.

The device in the line:

Code:

        Option          "Device"                "/dev/input/mouse1"

came from the /proc/bus/input/devices file.

you can look at it with, say less:

Code:

less -eX /proc/bus/input/devices

To find your Synaptics TouchPad device (/dev/input/mouseX where X is a digit).

Here is my entry that told me to use /dev/input/mouse1:

Code:

I: Bus=0011 Vendor=0002 Product=0007 Version=23b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input6
U: Uniq=
H: Handlers=mouse1 event6                             ### mouse1 here
B: EV=b
B: KEY=6420 0 70000 0 0 0 0 0 0 0 0
B: ABS=11000003

Thanks a lot guys, it worked.

dohpaz · 02-11-2009, 07:39 PM

Awesome info! Got my t30 synaptics tp working with this info thx a bunch!!!

uniostamer · 04-26-2009, 05:17 AM

Awesome! Works Great! How to add some other extras, for instance, Tap Zones??
And how to open /dev/input/mouseX?? I tried to open them with vi and less, but no result.
Thank you again!

@kjhambrick

I had some difficulties with touchpad when tapping and scrolling so I changed these 2 options, and now its perfect.

Option "FingerLow" "25"
Option "FingerHigh" "30"

I have had to change these values on different brands of notes, it seems it really depends on the type of touchpad used. I have seen one that only worked reasonably with values like 7 / 14 for Low & High.

Is there any utility out there to test / fine-tune touchpads or is it all a matter of trial-and-error?
Or a site with these values depending on brand / model of note?

Thanks a bunch friend, your suggestion sorted out my problem on my Slackware 12.2 laptop.
