Comment 85 for bug 1169376

@langel-vicente: I understand the frustration. However, as kentb wrote, the only system that's certified is Ubuntu 12.04. Also, you're right: Dell did provided Canonical with a Sputnik laptop-- one of the beta ones, without FullHD. Then Dell updated the hardware, and I don't know (but doubt) that they provided a new laptop to Canonical. Canonical isn't releasing updates and crossing their fingers, they're releasing updates for problems they can reproduce and fix. There IS no "proper testing" as far as this case is concerned: Canonical isn't a huge company with a collection of all these laptops on which they test every change. That's infeasible, especially considering that Canonical makes but a small percentage of kernel changes that you see.

It's worth pointing out that, as far as I've noticed, Dell merely got all the players to the table (Cypress, Canonical, etc.); that is certainly worth something, but they have never seemed to really support this from a software standpoint. The touchpad stuff wasn't Dell-- in fact, it was me. I don't work for either party-- I just got one of the beta Sputniks and hated the touchpad.

If you're a developer, are you able to perhaps start looking into this? You have a good starting point with the workaround posted!
