[SOLVED] Emulate3Buttons is not working

I have a mouse with 2 buttons a wheel that scrolls but can't be clicked. I created /etc/X11/xorg.conf.d/90-emulate3buttons.conf:

Section "inputClass"
  Identifier "middle button emulation class"
  Driver "evdev"
  MatchIsPointer "on"
  Option "Emulate3Buttons" "on"
EndSection

But it is not working. Xorg's log:

Any idea?

Re: [SOLVED] Emulate3Buttons is not working

Why not edit 10-evdev.conf instead? You've got two entries for matching pointer only one of which matches an event, right? I'm not sure how this stuff works but that seems as if it could have quite odd results...

What's ubuntu about it?

Re: [SOLVED] Emulate3Buttons is not working

I figured it out and it is not related to my specific hardware. There's no need to add or change xorg conf files. Gnome disables the middle button emulation by default and we need to run the following command (it will be remembered on future sessions):

$ gsettings set org.gnome.settings-daemon.peripherals.mouse middle-button-enabled true

I found it in the wiki: https://wiki.archlinux.org/index.php/Gn … use_button
