Comment 6 for bug 1390857

Cristopher, I followed your request and installed the upstream kernel:

$ uname -r
3.18.0-031800rc4-generic

There was no evident change whatsoever in the behaviour of the notebook: I run sudo apt-get upgrade, but no new drivers were installed. Finally, the result of xinput did not change:

$ sudo xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=9 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
