Comment 60 for bug 1305522

For those with the XPS 13's that still have a PS/2 interface showing up, it looks as if that doesn't seem to 'break' anything. The model I have in the lab has a much older touchpad firmware on it than the ones you guys have, so, that may be why things are showing up on your systems like they are.

@Jens, I would probably wait for an official fix rather than try and build and install your own kernel, especially if you haven't done it before. I would, however, give the test kernels a try here:

The XPS12 has the same i2c touchpad as the XPS13, but, I'm not positive about whether the touchscreens are the same though. I may have an XPS12 in the lab that I can try this on, provided it will power up :)
