Comment 83 for bug 217504

I just debugged the very same issue in bug 268429, and got to the same result. acpi_fakekey opens the right device and writes to it, but nothing happens for e. g. "150" (KEY_WWW).

As written in https://wiki.ubuntu.com/AcpiSupportDeprecation, we can either fix the kernel to convert *all* ACPI hotkey events to input key events, or keep acpi-support around to do this conversion in userspace.
