Comment 15 for bug 627890

I'm trying to use the procedure in README.keymap.txt.gz in order to fix the brightness keys (fn+f5 fn+f6) on my Sony Vaio Z21MN. They worked well in Lucid. Other special keys (mute, volume up, volume down,...) seem to work well.

$ /lib/udev/findkeyboards
AT keyboard: input/event2
module: input/event6

$ sudo /lib/udev/keymap input/eventX > /tmp/orig-map.txt

$ sudo /lib/udev/keymap -i input/event6
Press ESC to finish
scan code: 0x00 key code: fn_f5
scan code: 0x10 key code: fn_f6

$ cat /sys/class/dmi/id/sys_vendor
Sony Corporation
$ cat /sys/class/dmi/id/product_name
VGN-Z21MN_B

$ udevadm info --export-db > /tmp/udev-db.txt

I've also tryed to create a keymap:
$ cat /lib/udev/keymaps/module-sony-vaioz
0x00 brightnessdown # Fn+F5
0x10 brightnessup # Fn+F6
$ cat /lib/udev/rules.d/95-keymap.rules
......

It seems that the new local keymap is not loaded: the output of 'sudo /lib/udev/keymap input/event6' is unchanged and the keys continue to not work.

I'm available to test experimental changes.
