Upgrade decoupled the touch-pad

Hi

I did a complete upgrade (-Syu) after a long time, may be 3-4 months. It transferred 650 MB and completed successfully.

After the restart my touch pad does not respond though. This is an IBM ThinkPad T42. It has this "mouse stick" (the red button between the keys g, h and b), that works.

I've checked /etc/X11/xorg.conf, it wasn't changed. The "synaptics" section is still this:
Section "InputDevice"
        Identifier  "synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "LeftEdge" "1700"
        Option      "RightEdge" "5300"
        Option      "TopEdge" "1700"
        Option      "BottomEdge" "4200"
        Option      "FingerLow" "25"
        Option      "FingerHigh" "30"
        Option      "MaxTapTime" "180"
        Option      "MaxTapMove" "220"
        Option      "VertScrollDelta" "100"
        Option      "MinSpeed" "0.19"
        Option      "MaxSpeed" "0.35"
        Option      "AccelFactor" "0.0010"
        Option      "SHMConfig" "on"
#  Option       "Repeater"      "/dev/ps2mouse"
EndSection

Any idea?

Re: Upgrade decoupled the touch-pad

Hello,

When upgrading, pacman should have given a message regarding the CorePointer settings.  Try this in your xorg.conf file:

Section "ServerLayout"
    Identifier  "Simple Layout"
    Screen "Screen 1"
    InputDevice "Synaptics" "CorePointer"   <--------------
    InputDevice "Mouse0" "AlwaysCore"      <--------------
    InputDevice "Keyboard1" "CoreKeyboard"
EndSection

Remove any CorePointer/AlwaysCore from your mouse InputDevice section also.

HTH,
peart.

Re: Upgrade decoupled the touch-pad

Hi Peart

You are right, there was a message about Synaptics, but what? Sorry, ;-(

Thanks for the pointer. The following change brought the touch pad back into life:
  Section "ServerLayout"
    Identifier "Xorg Configured"
    Screen 0 "Screen0" 0 0
    InputDevice "Keyboard0" "CoreKeyboard"
    InputDevice "synaptics" "CorePointer" <--- it was "AlwaysCore"
    InputDevice "PS/2 Mouse" "CorePointer"
    InputDevice "USB Mouse" "CorePointer"
  EndSection

But there are other changes:
- The mouse stick doesn't react. (No problem as long as the touch pad works.)
- There are two rows of mouse buttons in these ThinkPads - three buttons over
  the touch pad and two buttons below the touch pad. Earlier both worked.
  Now I have only the lower row working.

I rarely use a USB mouse but it was enough to plug-in and it then worked.
I don't have one at hand to to test, it would be useful if it also worked.

Re: Upgrade decoupled the touch-pad

The new version of xorg (which would likely be one of your upgrades) only lets you have one Corepointer. For your other two you need to have it say "SendCoreEvents" instead.

Re: Upgrade decoupled the touch-pad

Hi mcmillan

That was it! I changed the last two "CorePointers" to "SendCoreEvents" and the matter was solved.

Thanks a lot!
