Looks like I found a problem.
"""sudo /lib/udev/keymap -i input/event7""" gives one of:
scan code: 0x00 key code: switchvideomode
scan code: 0x00 key code: battery
scan code: 0x00 key code: volumedown
scan code: 0x00 key code: stopcd
when I press fn+f5 or fn+f6.
Specifically..
At Brightne
Sorry for not being clear before but here is some clarification:
keymap -i doens't produce any output for brightness up/down. In fact,
none of fn+fX keys show anything when I "keymap -i input/event4". For
example, I can use fn+f9 to enable/disable touchpad but "keymap -i"
doesn't show anything.
After some investigation, it seems like the actual bug has nothing to do
with keymap.
Fn+F5/F6 actually does work. Keypresses are recognized as ACPI events
(see comment #1 above), and keymap does not show anything ever.
Currently brightness level goes something like this:
Left hand side: what No
