Whenever I turn on my laptop, the screen brightness is always on maximum, no matter how it was before shutdown; the bluetooth and wifi are always off. The touchpad is ok (if I turn it off, then reboot, it is sill off); the problem here lays on the touchpad status led: no matter what's the real state of the touchpad, the led is always off when I turn the computer on. The following scenario describes it better: (The led on is supposed to indicate when the touchpad is off) Touchpad ON -> Led OFF (OK, so I turn it off) Touchpad OFF -> Led ON (OK, let's reboot) Touchpad OFF -> Led OFF (Here lays the problem: the touchpad is still off, but the led is on) To get things normal again I have reboot the laptop with the led on, so the led will be off and everything will be in sync again. My laptop is a Dell XPS 15 (L502X) I'm using Ubuntu 12.04 LTS. I don't know what additional information I can provide (such as log files), but I'll be happy to provide any helpful resource.
