Dell XPS13 Developer Edition (Haswell) touchscreen not working in Ubuntu 13.10

After recently purchasing one of these laptops and deciding to update from vanilla Ubuntu 12.04 LTS to 13.10 I found the touchscreen was no longer working.

The solution, happily, turns out to be extremely simple. I updated to Kernel 3.12 from the Ubuntu Kernel PPA.

Download the appropriate deb files for your version of the OS, for me these were:

linux-headers-3.12.6-031206-generic_3.12.6-031206.201312201218_amd64.deb  linux-headers-3.12.6-031206_3.12.6-031206.201312201218_all.deb linux-image-3.12.6-031206-generic_3.12.6-031206.201312201218_amd64.deb

Then navigate in the terminal to the directory these were downloaded to and run:

sudo dpkg -i linux*3.12*.deb

Assuming there were no errors, reboot and you should be set.
