Comment 12 for bug 874237

I'm having the same problem. Emulate3Buttons does not work. I'm using a logitech wheel mouse, part of the MX5500, so pressing the wheel toggles the operation of the wheel itself rather than sending middle-click. With Emulate3Buttons, I was happy enough.

I tried changing the relevant section in /usr/share/X11/xorg.conf.d/10-evdev.conf to:

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
 Option "Emulate3Buttons" "True"
EndSection

...but, no dice. This is what I had to do in 11.04 to make it work; but it doesn't seem like it's working. Very frustrating; I use that copy/paste shortcut all the time.

Anybody have any good workarounds?
