I added to the ppa version for trusty too. It requires 'linux-generic-lts-vivid' package, which will be available soon in main repositories. But now it can be obtained from ppa:canonical-kernel-team/ppa.
Unfortunately there is kernel version 3.19.0-12.2. I have some brightness issues with that version. With 3.19.0-13 it is OK.
