Can't enable tap-to-click!

[CoolOppo]

I am running this on an Acer C720 with Ubuntu 14.10. I have tried a ton of different things, including using xinput and synclient, both of which I have an understanding of. I have also purged and reinstalled the package; it didn't work either.

I am not sure if this is a common issue, but I have looked all over the place for weeks (only once I got frustrated enough that it inhibited my daily work). If you know of any way to fix this, I would appreciate your input a ton (no pun intended)!

I'm using tap to click every day, so I know it works. You can list all the options with xinput like this:

xinput --list-props 12

where 12 is the id of your touchpad. It should be 12, but it may not be if you have another mouse plugged in. The relevant option to enable tap is: Tap Enable . You can enable it like this:

xinput --set-int-prop 12 "Tap Enable" 8 1

In addition to this driver, I have a lot of pre-built distros for the Acer C720 with this driver built in. See here: www.distroshare.com .

You can also find a config file that I'm using in my distros here: https://github.com/hugegreenbug/distro-mods/blob/master/acerc720_common/usr/share/X11/xorg.conf.d/50-touchpad-cmt-peppy.conf .

Thanks a ton; I'll try it right now!

[CoolOppo]

Huh, it's not working. I tried setting the property, and then I even saved that file to /usr/share/X11/xorg.conf.d/50-touchpad-cmt-peppy.conf, but it didn't work. Is it possible that somehow I have one or more drivers installed alongside xf86-input-cmt?

Here is what xinput --list-props 12 shows me (my trackpad's ID is 12 as well):

Somehow, there isn't any listing of Tap Enable anywhere in the file. Should I be using sudo possibly? Never mind that part about sudo. I just tried it, and it outputs exactly the same list.

[hugegreenbug]

Oh, you are still using the synaptics driver. See how the synaptics options are showing up? Move the synaptics config file somewhere else or rename it so it doesn't end in .conf. On Dec 17, 2014 4:31 PM, "CoolOppo" notifications@github.com wrote:

Alright, will do.

[CoolOppo]

Thanks for your help. I was able to remove the synaptics drivers, and I deleted /usr/share/X11/xorg.conf.d/40-touchpad-cmt.conf. I'm not sure if deleting that file was necessary though.

By the way, I do use your distro for Ubuntu 14.04 with Unity! I upgraded it to 14.10 a while ago though. Thanks for that too, because without it, I would still probably be using crouton on my Chromebook.

[hugegreenbug]

No problem. That file was useful btw. It is for this driver. Anything with "cmt" in the name is related. Cmt=chrome mouse driver.

Cool that you are using my distro. I have a 14.10 version now too. On Dec 17, 2014 4:55 PM, "CoolOppo" notifications@github.com wrote:

Whoops. Good thing I mentioned it.

[hugegreenbug]

I just realized that cmt != chrome mouse driver. I don't know what the t stands for, but you get the idea :). On Dec 17, 2014 5:29 PM, "CoolOppo" notifications@github.com wrote:
