fn-Keys (fn-F10 thru fn-F12) on notebook stop working after kernel upgrade
 
Hi, I recently upgraded my Fedora 12 kernel to find my fn keys from fn-F10 thru to Fn-F12 no longer work. These keys control the following:
fn-F10 (Webcam)
fn-F11 (Wireless radio)
fn-F12 (Bluetooth)

My problem is I cannot activate the bluetooth device, and this notebook (Clevo W765T) does not have any hardware or bios options to force the bluetooth on.

Fortunately the camera and wireless radio are on by default, so that is not a major issue, but it would be nice if these would work also.

The kernel that worked was Fedora 2.6.31.5-127.fc12.i686.PAE
while all the kernels since then have broken the keyboard fn-Key.

The output from lsusb when using the 2.6.31.5-127.fc12.i686.PAE kernel is:

The information from dmesg for the same kernel is:

I thought the following information might also help?

I have tried many possible solutions to resolve this, and all have failed. I have tried to use xev and various other keyboard mapping tools such as xkeycaps to try and remap the keyboard, but can't get this to work.

Any help is welcome...

fooka 03-17-2010 04:52 PM

for great justice...
 
bumping this thread, i have the exact same problem with fn-f10, fn-f11, and fn-f12 on a (Clevo D900F based) Sager 9280

appreciation to who (helps) pin(s) this down. I'm about to return the notebook because of this.

Also of note,

debian squeeze/sid here, linux-image-2.6.32-trunk-amd64
Fn-F1[012] keys don't work

ubuntu karmic, stock kernel
Fn-F1[012] keys DO work.

maybe it's a kernel option? i can't find a package that seems to care about bios/usb toggle hotkeys.

not hotkeys, not hotkey-setup, nothing.

what am I (are we) missing??

thanks in advance,
-m

In desperation I copied the same kernel configuration for the kernel that works, and rebuilt the kernel using the latest source etc and the configuration from the kernel that works. This did not help, so it looks like something in the kernel source changed, not one of the configuration options.

Perhaps this needs to be posted on the Kernel list?

fooka 03-18-2010 04:32 PM

well, before bothering the already wildly popular LKML, it's best if we nail down exactly what the problem is, so it isn't presented as "we don't know what it is, please fix it", since they won't necessarily know (or care) what it is either.

On the other hand, if we can nail down exactly what the problem is, and (assuming it's really a kernel problem) we hit LKML with "This is the specific problem, please fix it", then it stands a far better chance of being fixed.

i'm no further to finding a solution myself. I'm yet to compile the kernel again in search for the answer, but when i do, i'll post my results, if they differ.

Another thing to try (which I can't atm) is diffing the working kernel you have (probably a /boot/config-2.6.something.gz file) with the kernel you built using the old kernel's config (probably available in /proc/config.gz, or something) and just making sure indeed all options match.

If all the options -do- match, perhaps it's a) not a kernel difference, but a kernel-related userland difference (difference in initrd maybe?), or b) a module that isn't loading which should?

If you can inspect the contents of the old (working) kernel's initrd and the new (non-working) one's initrd, maybe there's a difference in there somewhere too?

also try comparing sysctl settings. Is it possible that identical kernel configs are fine, but the -settings- of some config somewhere in the kernels runtime is different and thus disabling it?

shooting in the dark,
-m

fooka 03-20-2010 04:33 PM

i'm beginning to agree with you that this is some kernel regression problem.

I noticed you are/were using fedora, having problems between an older and a newer kernel..

I've seen the exact same problem on a newer version under debian (2.6.32-trunk-amd32), and the problem goes away on the stock debian 5 (lenny) kernel 2.6.26-2-amd64..

the same is true on ubuntu.. since the commonality is the kernel between all three distros, it appears it is indeed related.

one hint i've got is "rfkill" might have something to do with it. rfkill is a module used for killswitching wifi. I don't know about bluetooth and whatever else, but i wonder if that module might be related to the problem.

more pokingaroundery required i guess.

JokeDude 03-21-2010 02:23 AM

I tried (for a 2nd time) to re-compile the kernel, double checking that the .config files from the working kernel where identical to the version I was about to compile. This still did not help.

As far as the rfkill option goes, I have tried to poke around with that, but all I get is the ability switch the wifi radio off/on. The bluetooth module is not affected by the same function, as it is not integrated into the wifi radio, but is a separate piece of hardware (factory option). The other strange thing that I have noticed, with both the working and non-working kernels, is that xev doesn't detect the fn-F10 thru fn-F12 keypress...

fooka 03-21-2010 04:03 PM

getting a little closer,

I've narrowed down that the difference is between 2.6.31 and 2.6.32.

I haven't narrowed down -what- it is, but ubuntu karmic koala ships with 2.6.31 and the fn-keys work, and 2.6.32 is the latest available in debian, and it doesn't work there..

so when i get another chance, i'll check the changelog between the two versions and see if there's a clue maybe.

-m

JokeDude 03-22-2010 03:59 AM

I concur, Fedora 12 also ships with the 2.6.31 kernel, and as soon as I ran the upgrade to 2.6.32 kernel, things went wrong.
I'll also see what I can dig up re the changelog.

fooka 03-23-2010 04:13 PM

sigh
 
I'm running out of time to return my notebook.

but even if i'd found the fix for this, there's still the lack of bios upgrade for my dual-headed problem

i notice there's a lot of happy sager/clevo users on the ubuntu forums, using 2.6.31.. when they get their shiny new upgrades to 10.04, i'm sure they'll come across this thread, since they'll undoubtedly come across this issue.

hope someone finds the answer. =(

fooka 03-31-2010 01:59 PM

sigh, well
 
i didn't have the heart to send it back.

problem persists in 2.6.33 as well. I'm still not closer to an answer. according to (debian package named) esekeyd's "/usr/bin/keytest", the only keys to register are the volume fn keys, though GNOME seems to see the brightness fn keys too. fn-f10 thru fn-f12 still useless.

=(

found a thread about bios versions: http://forum.notebookreview.com/show...=402119&page=9

but i seem to have the latest BIOSes already installed. so that's seems like a dead end.

wtf

JokeDude 03-31-2010 03:50 PM

I have since discovered that the Kernel regression goes back into the 2.6.31.12-174.2.22-fc12 version on Fedora 12. I am trying to see if I can find a the kernel for Fedora after 2.6.31.5-127.fc12 (which works), and slowly work my way through the various versions until I find the one that breaks the fn10 to fn12 keys.

fooka 03-31-2010 04:08 PM

oh cool!

ok, debian doesn't have a .31 in their repos, so i've grabbed 2.6.31.12 from kernel.org instead.. they'll have the intermediate versions too. if i have the probelm in 2.6.31.12 stock, i'll work my way backwards..

meet ya in the middle i guess.

cheers,
-m

JokeDude 04-22-2010 05:00 PM

Oh no! I have discovered that the fn-F1 (to lock the touch pad) has stopped working on the latest kernel 2.62.32-11-99.fc12 |-(

I'll need to try and go back to previous kernels to see when this one broke. I'll also test all the other keys while I am about it.

Indymaynard 05-10-2010 10:01 PM

Bluetooth
 
I noticed your post while Googling and was wondering what I could do to help? This problem is affecting my NP9850/M980nu. I would love to have the bluetoothey goodness, but the Fn+F12 key is not operational. I am using 10.04.

On my Windows partition, it's identified as being on:

Port_#0005.Hub_#0001

So, it seems to me that this button "plugs in" the device. Is there a way to activate it via software?

I'm not geek enough to know full well what to do, but I am geek enough to work at it if people give me the directions.

R/S,
Indymaynard

JokeDude 05-11-2010 11:26 AM

I have not yet had a chance to try and compile any of the 2.6.31 kernels yet, so if you feel that you could tackle this, it would help.

Regards
