For some weird reason, my mouse is sending multiple middle click events when I do a middle click at times. Happens once in a while - but not always. I'm fairly certain its a hardware issue.

Its a major annoyance as I paste using middle click a lot - and the same text get pasted 2-3 times.

I'm trying to get over the issue without having to buy another mouse.

Is it possible to disable multiple middle click event if they happen in quick succession?

xinput has a 'Evdev Middle Button Timeout' - but setting that to 1000 or so makes no difference.

  • I had the same in the past but the issue came and left randomly. As of today, it reappeared suddenly and can't do anything about it, restarting the machine and/or X doesn't do anything. Using Ikari Steelseries laser mouse on Gentoo Linux. Commented Dec 9, 2015 at 10:43
  • Gave up after trying a few things - bought a new mouse. That fixed the issue.

If it's a physical issue with the mouse, one option is to quit using the 3rd wheel and remap your mouse such that a simultaneous click of the two buttons (left and right) is interpreted as a middle click. You can do so via Section InputDevice in your xorg.conf file. Change Option Emulate3Buttons to yes and play with the delay time on Emulate3Timeout to a comfortable setting.
