The following information is applicable to:
  - anyone who wishes to do a fresh install of Ubuntu 12.04 on a Dell XPS 13 (or other laptop with a Cypress PS/2 Trackpad)
  - users who have applied my DellXPS PPA, but still do not get consistent trackpad recognition (xinput shows the trackpad as "ImPS/2").

The official "Project Sputnik" Dell XPS 13 LiveBoot/installer ISO has just been updated to include the latest (kamal5) kernel from my PPA. This ISO is basically an Ubuntu 12.04 installer, pre-configured to use my DellXPS PPA and with a few extra "developer" packages installed, as documented:

Using that sputnik-iso-20120719-0.iso and the "USB Installation Instructions" procedure documented there, you can prepare a USB stick which you can use to:
  1. test the Cypress trackpad functionality in the Live Boot test environment (without modifying your actual installed system), and/or
  2. install or re-install your system from scratch (back up your existing user data first!)

The Sputnik ISO isn't necessary for those users who already have consistent Cypress trackpad recognition (with my PPA kernel) -- its the same driver.

Users with already-installed systems are recommended to just apply my PPA: https://launchpad.net/~kamalmostafa/+archive/dellxps
