Touchpad tapping is the ability to tap on the Aspire S3 Ultrabook’s touchpad to register mouse clicks. It is convenient and quiet compared to depressing the touchpad and hearing the loud clicky noise.
Following the update to Cinnamon 2.0, touchpad tapping ceased to work. Of course, it did not work in Linux Mint 15 MATE either. However, this was due to an oversight instead of a faulty Linux distribution or update, and it is easily remedied. The solution is simple. It is not a kernel issue, Cinnamon issue, or Linux issue. It is a settings issue.
Linux Mint 15 Cinnamon
In System Settings, open the Mouse and Touchpad window and check the “Enable mouseclicks with Touchpad” checkbox. The touchpad now accepts tapping in Cinnamon 2.0. Apparently, the Cinnamon 2.0 update reset all of the previous settings and disabled this one. Enabling it again allows touchpad tapping.
Linux Mint 15 MATE
MATE never did register touchpad tapping, but this is because it was disabled by default instead of enabled by default as with Linux Mint 15 Cinnamon. To enable it, open the Control Center, select Mouse, choose the Touchpad tab, and in the General area, check the “Enable mouse clicks with touchpad” checkbox. MATE now accepts touchpad tapping just like the Cinnamon desktop environment.
Keep in mind that this does not enable fancy mouse gestures. Only the left click tap touch is restored, and it makes a difference.
