Disabling Middle Touchpad Button in Favor of Right and Left Click

hkothari · 2016-06-27 19:18:07

Hi all,

After one of the recent upgrades I ran (in the last couple months) the behavior of my touchpad seems to have switched and I'm not exactly sure how to get it back. Previously when I wanted to middle click (for pasting) I would click both the right and left touchpad buttons. Now that still works, but it also seems to pick up a the middle touchpad button for middle click as well (my touchpad doesn't have a middle button but it just uses the middle area).

The problem is, this middle button is really sensitive and quite frequently I will end up clicking it instead of the left button which I want to be clicking resulting in spurious pastes or other weird behavior (closed tabs in chrome, etc). So, I'd like to disable that button.

I've tried using xinput set-button-map to disable to middle click (running : xinput set-button-map 11 1 0 3) but this not only disables the middle button itself but also the middle click via right+left click. Is there anyway I can make it so middle click is only done when both right and left are pressed simultaneously but there is still no physical middle button?

I'm using a Dell XPS 13 from 2015. Below is the output of xinput:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]

    ↳ Dell WMI hotkeys                        	id=13	[slave  keyboard (3)]

Please let me know if I can provide more information and thanks so much for your help!

Gnome?
Are you using xf86-input-synaptics or xf86-input-libinput ?

hkothari · 2016-06-27 20:14:48

I'm not using gnome, I'm just using dwm. Honestly, it's a little unclear to me if I'm using synaptics/libinput. I think I'm using libinput but I'm not sure how to find out.

This will work (this time)

xinput list-props 11

This will change from boot to boot. the 11 is the ID and came from your previous post. The first column in the output is the driver that provides the property described by the line.

It appears as though I'm using libinput

I think you want to set the Click Method Enabled propert to 1, 0 using xinput

It is probably 1, 1 now.

Edit: Nope. I missed your post.

Do you use tapping? Try turning that off.

hkothari · 2016-06-27 21:03:42

Isn't tapping already disabled? It's set to 0

Yep. The hazards of looking at my settings for reference

I know I saw some people in the XPS 13 thread complaining about regressions in 4.5 with libinput, I'm running kernel 4.5 so this could plausibly be the issue: https://bbs.archlinux.org/viewtopic.php … 1#p1617221 althought I kind of feel like this came up a little while after I upgraded to 4.5

brittyazel · 2016-06-27 23:46:23

The most recent versions of libinput added a "middle" muse click region on touchpads, which is about 15mm wide in the center. This too has been messing me up, and I am also on an XPS 13 (2014 edition). You can read my thread with Peter here:

Well, the WONTFIX there is a disappointing response.. I guess I'll give synaptics a try. Thanks for the link though!
