The Acer Aspire One AOD270 and the same hardware rebranded as Packard Bell Dot SC need a couple of keymap fixups: 1. The switch-video-mode key does not do anything. Standard acer-wmi maps scancode 0x61 to KEY_IGNORE since typically these events are duplicate with the ACPI video bus. But on these models the ACPI video bus does not send events for this key, so map it. 2. The Brightness up / down hotkeys send atkbd scancode 0xce / 0xef which by default are mapped to KEY_KPPLUSMINUS and KEY_MACRO. These actually are duplicate events with the ACPI video bus, so map these to KEY_IGNORE.
Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
