here's a little more substance than just a teaser... I've got ubuntu 12.04 up and running quite satisfactory with touch and sound. Performance is just "okay" since I'm using software video drivers (hardware drivers aren't available on 12.04 at this moment). I'm also working on an issue where the screen doesn't turn off in software. This is probably fine for systems that turn on/off with the vehicle, but not great for an always on system.
The videos and picture above are part of the software platform I'm putting together to run on this thing. I should also note that Ubuntu is not the end solution [for me]. I'm just using it as a proof of concept. I'll start working more with mer as time goes on.
