Status in linux package in Ubuntu: New Bug description: I upgraded my (l)ubuntu to 15.04, which resulted in a non-detected touchpad, i.e., xinput does not list it. I then tried various mainline kernels, with the following results.

With all kernels, I have a problem with shutting down the computer: when shutting down, at some (random?) point, the computer "freezes" and the screen remains on (with the lubuntu logo which is displayed during the shutdown process.)
