Touchpad tap to click doesn't work on Arch Linux

After a recent update, i wasn't able to "tap to click" with my touchpad, because of the new version of xf86-input-synaptics.

You can solve this problem installing "libinput" and "xf86-input-libinput"

sudo pacman -S libinput xf86-input-libinput 

and removing "xf86-input-synaptics"

sudo pacman -R xf86-input-synaptics 

Reboot.



Another way is to downgrade to an earlier version of synaptics placed on /var/cache/pacman/pkg/

cd /var/cache/pacman/pkg/ 

ls

Search for a version of xf86-input-synaptics < 1.8.99

sudo pacman -U nameofthepackage 

 
Once the package is reverted, temporarily add it to the IgnorePkg section of /etc/pacman.conf, until the difficulty with the updated package is resolved.

Reboot and you're done.
