Nice, so there is hope after all!
No to just get it working... How do I go about this?

Oh, and canuckInOR, thank you for your post as well, it was helpful! I must have overlooked it yesterday, sorry about that!

Edit: I'm getting closer! Thanks to this blogpost I was already able to make it work. The only problem is the screen is not calibrated now, and the "xinput_calibrator" utility doesn't work as it should. I can run it, but after tapping the 4 points on the screen, I don't receive the message with the calibration data. So I can't put it in a configuration file. No idea what's going wrong here: the configuration utility just seems to quit back to desktop after the tapping of the 4 points.

But I can tell you that, after the calibration, I can use the screen as it should ; it's just that the values are not remembered after reboot. I'll look further into this and keep you guys updated.
