Ubuntu – Touchpad 2 finger scroll ends with a right click, text marking lag

mousemulti-touchtouchpad

Some recent update made my two-finger scrolling unbearable. Every single time I scroll it ends with a right click.

Another thing I've noticed is a sort of lag when I'm marking text. This is also really annoying when you use your computer for work. It's like the left click has a delay of a second when you try to mark something to copy etc.

Reinstall the drivers:

sudo apt-get --purge autoremove xserver-xorg-input-synaptics && sudo apt-get install xserver-xorg-input-synaptics

I know it's not what you really want (completely automatic?), but there is an easy to make keyboard shortcuts to disable and enable the touchpad.

From your xinput list, the id for your touchpad is 12. Use this command to disable it:

xinput set-prop 12 "Device Enabled" 0

Use this to enable it:

xinput set-prop 12 "Device Enabled" 1

Bind these commands to your custom shortcuts (Keyboard / Shortcuts / Custom Shortcuts). Perhaps this can be made to a script?

Ubuntu – Chrome two finger scroll then right clicks

I had the same issue only in Chrome too.
You can solve this problem by using 50-synaptics.conf config file :

wget http://hgdev.co/wp-content/uploads/50-synaptics.conf
sudo mkdir /etc/X11/xorg.conf.d
sudo cp 50-synaptics.conf /etc/X11/xorg.conf.d/

You can also manually edit this config file to better fits your preferences. The Arch Wiki page on Synatics trackpad will be helpful for this.
