Middle mouse button stopped working

Hello,

After a system upgrade which updated, among other things, xorg-xinput to 1.5.2-1, my middle mouse button, as well as the middle mouse button emulation with left mouse button + right mouse button, stopped working.

The middle mouse button is a scroll wheel. Scrolling up and down still works, just not pressing it. It actually can be pressed either left or right; only the left previously registered as a middle mouse click.

xev reports the left shift of the mouse wheel as button 6 and the right shift of the mouse wheel as button 7.

It doesn't seem to work in any app; I can't use it to paste, nor to enter autoscroll mode in Firefox.

From xorg.conf:

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

I've tried a number of things -- removing the EmulateWheelButton line, changing ZAxisMapping to just "4 5". None had any effect.

Any suggestions would be very much appreciated. I'm completely lost without the ability to paste.

Re: Middle mouse button stopped working

Add this:

Section "InputClass"
    Identifier "whatever"
    MatchIsPointer "on"
    Option "Emulate3Buttons" "on"
EndSection

to your /etc/X11/xorg.conf.d/10-evdev.conf (or any Xorg conf you want) and you will again have middle click emulation. I don't know if this will solve your problem regarding your actual middle button.

That didn't affect the actual middle button behavior but the middle click emulation does work again as you said, which is all I really need. Thank you!

Re: Middle mouse button stopped working

Thank you very much augegr!

I find that clicking the left and the right button at the same time to emulate the wheel click is much more comfortable. Since the input configuration changed from Hal, I couldn't find a solution to this problem.

Now the changes will require the xserver to be restarted, or is it possible to restart another program?
