If you’ve been following project Sputnik — a developer laptop pilot based on Dell’s XPS13 ultrabook and Ubuntu 12.04LTS — you’ll know that the biggest draw back in these initial weeks has been the lack of multi-touch support in the touchpad. For some this has been annoying, for others this has been such a pain that they have put their system aside until the driver becomes available. I’m happy to say that as of a few hours ago, a fully open source driver is now publicly available.
Here are the details from Canonical’s Kamal :
The Sputnik ISO image is pre-configured to use the PPA for updates so all systems which were previously installed with that ISO will automatically be offered the PPA update and their touchpads will just start working. Furthermore, even systems which are installed now (or later) using that ISO will still automatically be offered the updated PPA kernel when they do their first software update.
There is also a link on the Sputnik PPA page to the Cypress driver patch (and also to the whole DellXPS patch set), so folks building their own kernels from source can get it from there.
Shout outs to…
A big thanks to Kamal from Canonical, Mario on the Dell side for driving this, and the vendor Cypress for doing the work!
