I just upgraded from kernel 2.6.18 to 2.6.19. Since then I can reliably get an 'accidental' double click if I click the mouse once really fast (one short click). It happens on both the sets of touchpad buttons and my external USB mouse.

Any ideas?

Note also, to get X to start after the upgrade I had to make a few changes.
I changed the PS/2 to be the CorePointer and also the device for the Touchpad from event1 to event3.


Code:

Section "ServerLayout"
   Identifier   "X.Org Configured"
   Screen   0   "Screen0" 0 0
   InputDevice   "Keyboard0" "CoreKeyboard"
   InputDevice   "USB Mouse" "AlwaysCore"
   InputDevice   "PS/2 Mouse" "CorePointer"
   InputDevice   "TouchPad" "AlwaysCore"
EndSection

Section "ServerFlags"
   Option   "AllowMouseOpenFail" "true"
  #Option "Xinerama" "false"
   
EndSection



Section "InputDevice"
   Identifier   "Keyboard0"
   Driver   "kbd"
   Option   "CoreKeyboard"

   Option   "XkbModel" "pc105"
   Option   "XkbOptions" "grp:toggle,grp_led:scroll"
   Option   "XkbVariant" ",winkeys"
EndSection



Section "InputDevice"
   Identifier   "PS/2 Mouse"
   Driver   "mouse"
   Option   "Protocol" "IMPS/2"
   Option   "Device" "/dev/misc/psaux"
   Option   "Emulate3Buttons" "true"
   Option   "Emulate3Timeout" "70"
   Option   "SendCoreEvents"  "true"
   Option   "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
   Identifier   "USB Mouse"
   Driver   "mouse"
   Option   "Device" "/dev/input/mice"
   Option   "SendCoreEvents" "true"
   Option   "Protocol" "IMPS/2"
   Option   "ZAxisMapping" "4 5"
   Option   "Buttons" "5"
EndSection

Section "InputDevice"
   Identifier   "TouchPad"
   Driver   "synaptics"
   Option   "Protocol" "event"
   Option   "Device" "/dev/input/event3"
   #Option   "Device" "/dev/input/event1"
   Option   "LeftEdge" "130"
   Option   "RightEdge" "840"
   Option   "TopEdge" "130"
   Option   "BottomEdge" "640"
   Option   "FingerLow" "7"
   Option   "FingerHigh" "8"

  Option "EdgeMotionMaxSpeed" "200"
  Option "UpDownScrolling" "1"
  Option "CircularScrolling" "1"
  Option "CircScrollDelta" "0.1"
  Option "CircScrollTrigger" "2"
   Option   "SHMConfig" "on"
   Option   "UseShm" "on"
  Option "Emulate3Buttons" "on"
EndSection

I usually use the 'auto' protocol which (now) works with ZAxisMapping properly. But I don't think that would cause this problem.

usually ps2 mice still have /dev/input/mouseX device files too, and so /dev/input/mice should read from them. again, i don't think that would cause this problem, but i don't know. Maybe your mouse is old and breaking? the buttons do tend to wear out after many years of use...

No the touchpad buttons also now have this double-click thing, so it's not just wearing out.
I'll fiddle with using different device nodes to see if that fixes things.

perhaps the ps2 mouse shouldn't be core pointer then?

I have a similar problem, only my accidental double clicks are not reproducible (but frequent). I have upgraded from 2.6.19-ck2-r3 to kernel 2.6.19-ck5.

Also, I don't know if it is related, but my Thunderbird sometimes relaunches itself (so that 2 copies run).

It doesn't happen under Windows on a dual boot computer, so it's not the hardware.

My xorg.conf mouse section:

Code:
Section "InputDevice"
   Identifier  "Mouse0"
   Driver      "mouse"
   Option      "Protocol" "ImPS/2"
   Option      "Device" "/dev/input/mouse0"
   Option      "Buttons" "3"
   Option      "ZAxisMapping" "4 5"
EndSection


I have not changed it for a very long time.

Edit: I have a feeling that it happens only for a while after X is started. After working an hour or so, it seems to work fine. What is strange if this isn't??

Edit2: I think it is my (hardware) mouse. It does the same under Knoppix with old kernel and maybe I don't use Windows enough to experience it there.

Edit3: Yes, it is was the mouse hardware. It did it under Windows, too, and when I replaced the mouse, the problem went away.

I changed the core pointer back to the touchpad (after changing the device nodes which were different after the kernel upgrade) and the problem went away.

Thanks for the help.

That is my only mouse.

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "Auto"
Option "Emulate3Buttons"
Option "Device" "/dev/input/mice"
EndSection
