Hello there,

just registrated with my first question here.

Short facts:

Samsung X120
Distro:2.6.33-ARCH

I installed samsung tools. Now i can switch on/off Backlight, Bluetooth, Fan Adjustment works, Webcam can be switched on/off and the Wireless Card switcher works - but not Using the FN-Key! The FN Key dont seems to work :(

What suggestions do you have to mute or adjust the loudness?
And how will i be able to control the brightness manually?

Maybe someone had the same issues?

Regards!

Hi,
please use the 'xev' command line utility to check if your FN keys are correctly recognized.
If they are not, add your model to the array of samsung models in '/lib/udev/rules.d/95-keymap.rules' and '/lib/udev/rules.d/95-keyboard-force-release.rules', then reboot and recheck.

If keys are recognized by 'xev', then probably you have some dependencies missing for samsung-tools... how did you install it on your arch box?

There is now a PKGBUILD on AUR, try using it. ;)

Hey there,

there is no xev event recognized when pushing fn+brighness up n down.

Code:
xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'


Due to the fact that samsung tools only work without pushing fn.

Then i tried:
Code:
[steffen@x120 ~]$ dmesg|tail -5
atkbd.c: Use 'setkeycodes e009 <keycode>' to make it known.
atkbd.c: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e008 <keycode>' to make it known.
atkbd.c: Unknown key pressed (translated set 2, code 0x89 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e009 <keycode>' to make it known.



but now i dont know how to go on.

how do i find out the value to add my model to the udev rules?

Sorry i m not very linuxish :(

I installed samsung-tools from aur.

Regards

Use this command to get the exact name of your model:
Code:
dmidecode -s system-product-name
Then add it to the Samsung models' array in the udev files '/lib/udev/rules.d/95-keymap.rules' and '/lib/udev/rules.d/95-keyboard-force-release.rules'.
