Touchpad gestures don't work on Dell XPS 15 L521x

I'm trying to get multi-touch gestures working on my Dell XPS 15. Two finger scrolling works but three or four finger gestures do not. I know that the touchpad is capable of multi-touch gestures because it works fine in Windows. I've tried several things already:

• Installing touchegg from the repository
• Installing touchegg from source
• Installing Sputnik kernel and policykit updates from Sputnik PPAs

The first fails with a segmentation fault when run, the second gives errors during compile about missing files, and the third installed fine but nothing changed. Compilation errors can be seen here.

Solution 1:

Try this solution.

Install xserver-xorg-input-multitouch and xserver-xorg-input-synaptics

sudo apt-get update
sudo apt-get install xserver-xorg-input-multitouch
sudo apt-get install xserver-xorg-input-synpatics

It has solved touchpad issues on other brand name laptops, don't know about Dell.
