Bug Description

Notebook info from dmidecode:
Manufacturer: SAMSUNG ELECTRONICS CO., LTD.
Product name: R59P/R60P/R61P
Version: 05YI

Ubuntu 8.04.1 Release: 8.04
Linux hell-nb 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux

Some Fn keys not work:

1. Fn+F2 Battery status: no keycode, no unknown keys in dmesg, no acpi events
2. Fn+F3 Monitor switch: no keycode, no unknown keys in dmesg, no acpi events
3. Fn+F5 Backlight off: no keycode, no unknown keys in dmesg, no acpi events
4. Fn+F8 powersave mode switch: no keycode, no unknown keys in dmesg, no acpi events
5. Fn+F9 WIFI on/off: no keycode, no unknown keys in dmesg, no acpi events
6. Fn+Up Brightness up: no keycode, no unknown keys in dmesg, no acpi events
7. Fn+Down: Brightness down: no keycode, no unknown keys in dmesg, no acpi events

Other Fn keys produces scan codes and work as needed.

I test scancodes with showkey -s, tail -f /var/log/dmesg; acpi events with tail -f /var/log/acpid

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in hotkey-setup.

I have updated hal-info to version 20090128-0ubuntu1~intrepid1. Now some Fn keys working, but with new bugs. For example: when I press Fn+Up brightness changes in cycle.(brightness change window does not disappear). I think because some keys (actual fn+something combinations) generate Down events but no Up events.

I applied the patch from zl0i. Would someone with Samsung R60 help test the patched kernel.
They are available at
  http://people.ubuntu.com/~lexical/archive/lp253874/

  2.6.27 (intrepid kernel)
  2.6.28 (jaunty kernel)

Please report the testing result in order to get the patch into the Jaunty/Intrepid SRU.

I `ve tested this pathed kernel. The patch was applied right. Here the result after it:
1. Fn+F2 Battery status: OK
2. Fn+F3 Euro (In my model): NOT - it sends chain of keys like Alt + 1,2,3 (like in Win to print special characters) (did somebody knows how to fix it?)
3. Fn+F4 Switch displays: OK
4. Fn+F5 Backlight off: NOT - it sends keykode and in X it recognised like "XF86Launch1", but function not work (anybody knows utility to swtch off backlight?)
5. Fn+F7 launch special soft: NOT - it sends keykode and in X it recognised like "XF86Launch2", but function not work (so you can launch any soft by this key)
4. Fn+F8 launch special soft: NOT - it sends keykode and in X it recognised like "XF86Launch3", but function not work (so you can launch any soft by this key)
5. Fn+F9 WIFI on/off: NOT - it sends keykode and in X it recognised like "XF86WLAN", function not work beacause of ath5k driver (in version of ubuntu 9.04 driver not provide rfkill), so you need update to latest ath5k driver or new kernel 2.6.30 (Can anybody test it?)
6. Fn+Up Brightness up: OK
7. Fn+Down: Brightness down: OK
So, the patch is correct, it`is do what it`s must do. Fn keys work, but not all functions work. Other problems can`t solved by this patch.
P.S. Is this fix will available in kernel from official repository and how soon?

Many owners of other models of samsung notebooks have the same problems and I`ve made same patches for them and it works. Shel I post new bugs or can post patches here? One more question: Will this patch\patches send to kernel.org?
P.S. : I`ve made some scripts to provide functions for "empty" fn keys, Post theme?

zl0i:
  You you want people here to help test, you can post your patch here. I can also help to make your patch upstream (in the mainline kernel tree).
  If your new patch of other models also work on R60, you can post it here. Or you can create another new issue.

  I don't understand what functions for "empty" fn keys are. Could you please explain a bit?

Keng-Yü Lin:
OK, My patch and other (for q210, r518 and maybe many others) are tested by some forum.ubuntu.ru users and them work correct. I just want to see these patches in mainline kernel, because I don`t want to patch kernel every time I update it. So ,please, help to make them upstream.
In old posts of bugzilla.kernel.org I saw same discussion. They said it is not good solution to make many patches for many models. The patches are same if not for all but for many models ( such as r60, q210, r518...). And this was a barrier to apply all patches to kernel. So the code after all patches will be "dirty". But users just want Fn keys work. Now It is your choose.
"empty" fn keys are:
fn+f3 - "euro" - I made a simple python script for it (print euro sign in input-box on focus).
fn+f5 - backlight off - I made a simple bash script for it.( call in it "xset dpms force off")
fn+f7 - samsung tool (in win) - you can bind everything on it.
fn+f8 - powersave mode switch - I made a bash script for it too. (just switch backlight to lowest level and cpu throttling to 50%)
I call them "empty" because linux is not provide functions for them and I make for them my own scripts. And switch wifi (fn+f9) will work if wifi driver updated to latest or kernel to 2.6.31. So fn+f9 works fine.

Can you execute "sudo dmidecode" and find the field "Product Name". Reply me its content here. I will try to generate a testing kernel deb for you.

@zl0i
Could you try the "empty fn key" with the following step:

1) dmesg | grep GPE
  will show you something like "ACPI: EC: GPE = 0x11, I/O: command/status = 0x66, data = 0x62"

2) cat /sys/firmware/acpi/interrupts/gpe11
  use the number in 1)

3) press fn keys and cat again to see if the number increases

  Please skip my last comment. I missed some point and get it back after re-reading the thread.

  You can use `xbacklight -set 0` to turn off the backlight.

    I skiping #14 - but number increases, if it helps. For #15: xbacklight -set 0 doesn`t help - I`m using 'xset dpms force off' instead.
    #16: anyway Thanks a lot, this words "in .32 there will be a way to adjust the bitmap through sysfs", gives more hope. I think a new patch will help other laptops without kernel patching. Thank you for response.

Hello,

I got a Samsung Q320 aswell and I have the same problem. The only fn-key which works is the mute/unmute sound. I can't enable/disable the wifi, BT, can't change brightness, can't switch on external screen. etc...

The most horrible thing is that ubuntu doesn't support the energy saving mode of this laptop. On Vista the battery live is about 5 hours and more. On Ubuntu exactly the half, about 2,5 h.
That's very annoying.

Thanks for any help.

Will post anything you need.

Bye

@scottnn, mpw

Would you like to try the patched karmic kernel package (http://people.canonical.com/~lexical/archive/lp253874/linux-image-2.6.31-16-generic_2.6.31-16.50lp253874lexical1_i386.deb) and report whether it works well. Not all the function keys works without some user space modification. Please refer to the previous discussion.

@zl0i

Would you also like to test the patched karmic deb. Since the sys interface will not be available until .32 kernel, this patch may be worthy of an SRU.

@Keng-Yü Lin
Yes, all keys sends release events, but I cant decrease brightness and toggle wifi - so I think problem is in udev or else, but not in patch. rfkill works, fn-f9 binded to XF86WLAN, but maybe XF86WLAN not binded to toggle wifi. And last - all key quirks migrated from hal to udev fine.(You can check it in /lib/udev/rules.d/95-keymap.rules and /lib/udev/keymaps/samsung-other)
