Samsung X120 keyboard quirks

November 3rd, 2009 flo Leave a comment Go to comments

As suspected, the Samsung X120 notebook has the same keyboard quirks as many other Samsung laptops, so that some of the function keys don’t work correctly under Fedora 11. There are two problems and fixes needed. One, the kernel needs patching so that the quirks with missing key release events are also applied to the X120 (kernel bug 14052). Secondly, HAL needs patching to connect the function keys to turn the brightness up and down, etc., in the manner described by Fedora bug 504009 and Ubuntu bug 399911 (and many others).

However, I have confirmed that grabbing and patching kernel-2.6.30.9-90.fc11.src.rpm works me.

    I guess I’ll be waiting for kernel 2.6.32 to get the fn-keys fixed as I have no clue about patching a kernel :)

    Hi! I have a samsung x120 too, and I have problems with keyboard, but above all with the impossiblity to turn the brightness up and down and to turn off the wireless…
    I have also updated the kernel to the latest version (2.6.32-11), but nothing changed…

    Could you explain me how did you manage to get it work please?

    Thank you!

    Assuming that 2.6.32 has the fix, you’ll also need the Fedora bug to be fixed so that the keys are attached to the correct functions, or correct the HAL file as described in bug 504009.

    As I’ve now upgraded my desktop to Fedora 12 successfully, I’ll be updating the X120 shortly (maybe the weekend, if I’m lucky). At that point I’ll revisit the HAL patch and report back. If I forget, please ping me!

    Ah, I see that the latest Fedora 12 kernel is 2.6.31.12, which means that I won’t be trying this yet. I’m not willing to run Rawhide on my laptop :-)

    Well, thank you anyway…I also forgot to say that I don’t use Fedora, but Ubuntu…anyway, on Ubuntu 9.10 (kernel manually updated to 2.6.32-11) it doesn’t work, also if I try to change the brightness from the power management…so I don’t think it’s a keyboard problem…I hope this bug will be fixed as soon as possible because it is really very annoying…especially for the battery life…if I want to change brightness I have to enter winzozz, change it, reboot and enter linux -.-

    I made a script to change brightness from console:
    #!/bin/bash

    echo “Input brightness level (0-99)”
    read i
    sudo setpci -s 00:02.0 F4.B=$i
    exit 1
