[SOLVED] X.org Problem: Synaptic Toucpad

druuna · 09-03-2011, 03:46 AM

Hi,

Just to make sure: You have enabled the following entries in your kernel?

Code:

Device Drivers  --->
  Input device support ->
  *   Mice  ---> 
    *   PS/2 mouse
    *     Elantech PS/2 protocol extension
    .
    .
    *     Synaptics I2C Touchpad support

The above also makes me believe that both the mouse and the touchpad are seen as the same device. What is the output of:

Code:

cat /proc/bus/input/devices

You might want to try to remove the mouse related entry from the xorg.conf file and add a toucpad related one.

Taking the xorg.conf file from post #13 as an example; Change this part:

Code:

Section "InputDevice"
     Identifier    "Mouse0"
     Driver        "mouse"
     Option        "Protocol" "auto"
     Option        "Device" "/dev/input/mice"
     Option        "ZAxisMapping" "4 5 6 7"
EndSection

to this

Code:

Section "InputDevice"
     Identifier    "Mouse0"
     #Driver        "mouse"
     #Option        "Protocol" "auto"
     #Option        "Device" "/dev/input/mice"
     #Option        "ZAxisMapping" "4 5 6 7"
     Driver "synaptics"
     Option "CorePointer"     
     Option "Device" "/dev/input/mouse0"
     Option "Protocol" "auto-dev"
     Option "HorizTwoFingerScroll" "1"
     Option "VertTwoFingerScroll" "1"
     Option "TapButton1" "1"
     Option "TapButton2" "2"
     Option "TapButton3" "3"
EndSection

As stated in my first reply (post #2) I do not have any touchpad experience, so the options might need tuning and you might need to add additional touchpad options. I only used the ones that I believe to be necessary. Here's a list of other options that might come in handy (values are as found on the internet and might need changing):

Code:

Option "AccelFactor" "0.0320"
Option "BottomEdge" "680"
Option "CircScrollTrigger" "8"
Option "CircularScrolling" "1"
Option "CoastingSpeed" "0.13"
Option "Emulate3Buttons" "true"
Option "FingerHigh" "30"
Option "FingerLow" "25"
Option "HorizScrollDelta" "20"
Option "LBCornerButton" "2"
Option "LeftEdge" "60"
Option "LockedDrags" "1"
Option "MaxSpeed" "0.72"
Option "MaxTapMove" "220"
Option "MaxTapTime" "180" 
Option "MinSpeed" "0.6"   
Option "PalmDetect" "0"
Option "RBCornerButton" "0"
Option "RTCornerButtom" "0"
Option "RightEdge" "1070"
Option "SHMConfig" "on"
Option "SendCoreEvents" "yes"
Option "TopEdge" "1700"
Option "TouchPadOff" "0"
Option "VertScrollDelta" "100"

Hope this gets you going again.

Hi,
Thanks for the reply. About the kernel, I've double-checked it.
Here is the output of /proc/bus/input/devices:

Code:

I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input10
U: Uniq=
H: Handlers=mouse0 event10 
B: EV=b
B: KEY=6420 0 30000 0 0 0 0 0 0 0 0
B: ABS=3

This is the only pointing device I have, and the only one appear in the input device list. The others are just keyboard and mic, which are irrelevant to my case. However, I still put the complete output for you to see, just in case.

FYI, I am using Asus Eee PC 900A.

Have you tried out the new changes to the xorg.conf file I proposed?

TKH · 09-04-2011, 06:34 AM

Actually, my original configuration file is like that (the #12 is the new one you told me to make). Some of these were put to the xorg.conf.d/50-synaptics.conf, thus you didn't see. I don't really get the difference between "auto-dev" and "auto".

alike != the same.

Adding and/or having synaptics/touchpad entries is not the point (as explained).

That's not the only difference.......

Sorry to say this, but you don't seem to interested in a solution. And even though I pointed out not being familiar with setting up a touchpad I did spend time trying to help you and creating a (possible) working configuration by searching on-line and putting 1 and 2 together. It sure seems you don't appreciate the effort made.

Guess I'm done here.

Hey,
IT WORKED!!!
So as we thought that then error was caused by the driver double loading (in my case they were evdev and synaptics module).
What I did was to disable one of them by adding "ignore" option (I chose to disable the loading in evdev).
Thank you very much!!!

So now with the twm working, what should I do next? How do you add some stuff on it?
