           Summary: keys for adjusting display brightness don't work as
                    expected on ASUS 1005p netbook
           Product: ACPI
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Video
        AssignedTo: acpi_power-vi...@kernel-bugs.osdl.org
        ReportedBy: bugzilla.kernel....@rolf.leggewie.biz
        Regression: No


Looks like I have found another bug related to the N450-based ASUS 1005p
netbook. The hotkey combination for increasing and decreasing display
brightness does not seem to work correctly.  As written in
https://bugs.launchpad.net/linux/+bug/513921 the display brightness does not
increases monotonically.  Not sure if the root cause of this is the kernel bug
that apparently the ACPI events are not translated to input events (see comment
4).  acpi_listen told me the corresponding events were "hotkey ATKD 0000002d
0000000c" for the hotkey to lower screen brightness and "hotkey ATKD 0000002e
0000000c" for increasing it.  Let me know if you need further information.
