Synaptics support kills my mouse

Synaptics support kills my mouse

[Thomas Molina]

Since about 2.5.72 the "new?" synaptics touchpad support kills my system.  
I have a Compaq Presario 12XL325, which does have a synaptics touchpad, 
but has always acted like a regular PS/2 mouse.  The last version  of the 
kernel which worked correctly in this respect was 2.5.72 bitkeeper as of 
June 18.  The next version I was able to test was 2.5.73 as of June 24.  
>From this version forward I get no mouse at all.  My recollection is that 
the June 18 bitkeeper version had optional synaptics support; including 
it broke mouse support, but compiling it with only ps/2 support enabled 
the mouse support.

You can, but I wouldn't recommend that. Having a module allows you to change 
the behaviour runtime (even inside X).

Further update.  I can get the same effect/workaround by making the mouse 
support built in (my preference) and specifying the above option on the 
kernel options line.

It is an ugly workaround, but it works.  Thanks.

I'm not the author of the driver but I do have my touchpad mostly working
(tap to click doesn't work but I can move the pointer and click buttons).

Make sure you load the synaptics module in XF86Config... then you want
your pointer section to look something like:

Section "InputDevice"
        Identifier      "MouseS"
        Driver          "synaptics"
        Option  "device" "/dev/input/event1"
        option  "protocol" "event"
        Option  "edges" "1900 5400 1800 3900"
        Option  "Finger" "25 30"
        Option  "MaxTapTime" "20"
        Option  "MaxTapMove" "220"
        Option  "VertScrollDelta" "100"
        Option  "MinSpeed" "0.02"
        Option  "MaxSpeed" "0.18"
        Option  "AccelFactor" "0.0010"
        Option  "Emulate3Buttons" "on"
        Option  "EmulateMidButtonTime" "20"
EndSection

it uses the event devices, not the mouse devices.

Same issue on my Dell Latitude C640. No cursor in X, no cursor in
  framebuffer. gpm silently waits in select() even pointing to
  /dev/input/mice instead of /dev/psaux.

Re: Synaptics support kills my mouse

[P. Christeas]

It is true, 2.5.73 unconditionally detects and tries to use the Syn. Touchpad 
in 'absolute mode'. I wouldn't blame the authors of the module, however. They 
are already doing a great job :).

I 've read the code to see what's wrong and found that the problem is that the 
Touchpad itself doesn't report any data to the PS/2 port. The code still 
looks conforming to the specs.
However, you shouldn't give up 2.5.73 because of that. You can still use the 
PS/2 compatibility mode
 o Compile the ps mouse as a module "psmouse"
 o Arrange so that the module is loaded with the option "psmouse_noext=1"
 o Have gpm and X (you can even use both of them) read /dev/input/mice as an 
exps2 or imps2 mouse (Intellimouse Explorer PS/2) .

I don't think the "event interface" has any support yet. Nor the synaptics 
driver.
Reading from /dev/input/mice means that the psmouse module doesn't have to be 
loaded before X starts. You can safely rmmod/modprobe the module while X run.
You may find that tapping with the finger may not work (produce 'click' 
effect). I hope next release will have a fix (contact me in personal until 
the official patch is out).

I have the same problem. I'm using MaxData Mbook 1000T which has
synaptics touchpad too and it stopped working in .72 and still doesn't
work in .73 :-(

Synaptics Touchpad, model: 1
 Firware: 4.1
 Sensor: 8
 new absolute packet format
input: Synaptics Synaptics TouchPad on isa0060/serio2
mice: PS/2 mouse device common for all mice

I tried to use XFree86 4.3.99.6 with
http://w1.894.telia.com/~u89404340/touchpad/ driver but that doesn't
work either:
(**) Option "Device" "/dev/input/mice"
(**) Option "LeftEdge" "1900"
(**) Option "RightEdge" "5400"
(**) Option "TopEdge" "3900"
(**) Option "BottomEdge" "1800"
(**) Option "MaxTapTime" "15"
(**) Option "MaxTapMove" "220"
(**) Option "VertScrollDelta" "100"
(II) xfree driver for the synaptics touchpad 0.11.3p2
(**) Option "CorePointer"
(**) Mouse0: Core Pointer
(II) Keyboard "Keyboard0" handled by legacy driver
(II) XINPUT: Adding extended input device "Mouse0" (type: MOUSE)
Synaptics DeviceInit called
SynapticsCtrl called.
Synaptics DeviceOn called
(II) xfree driver for the synaptics touchpad 0.11.3p2
Synaptics DeviceOff called
SynapticsCtrl called.
(--) SAVAGE(0): Chose mode 117 at 85Hz.
Synaptics DeviceOn called
(II) xfree driver for the synaptics touchpad 0.11.3p2
Synaptics DeviceOff called

Doesn't work means that button presses nor touchpad moves are not detected.

btw. which driver provides /dev/input/inputX (as in xfree synaptics
driver documentation) ? I found only /dev/input/eventX driver.
