Public bug reported:
I've a Clevo M725 notebook rebranded as Santech T45. All the previous ubuntu
releases support laptop hotkey without extra set up, but the last release seems
that broke the support of them.
Almost all the acpi event are disappear. In particular, I notice that are not
processor recognized:
- the ac_adapter plug and unplug
- battery charging/discharging event
- suspend button*
- backlight hotkey event*
- low power mode button*
- lid open/close
The bug is reproducible booting the laptop with a kubuntu 11.04 live. Using
acpi_event command I've saved the output for low power mode button, backlight
up and down and suspend button:

On the other hand, in kubuntu 11.10 there are no output at all.
