Bug #640992 “ThinkPad Edge 13(AMD): thinkpad_acpi,wireless hotke...” : Bugs : linux package : Ubuntu

Bug Description

Binary package hint: linux-image-2.6.35-22-generic

The wireless hotkey can enable and disable the bluetooth.The wireless hotkey can't control the WiFi.Module thinkpad_acpi is loaded.
ThinkPad Edge 13 (AMD platform, the cadename is Berlin1.2 )and ThinkPad Edge 14 (AMD platform,the codename is London)also have this bug.
But on intel platform(Thinkpad Edge 13,the codename is Berlin and ThinkPad Edge 14 ,the codename is London),the wireless hotkey is functional.

If you need any futrther information,please let us know.

@ allenlan,
Just to be clear it is only the hot key that is not working, correct? Wi-Fi and Bluetooth work on their own? Just want to make sure there is a workaround where these components are functional.

The wireless hotkey is not functional for wifi.
Both wifi and bluetooth have the right function.

Garrick Yang (garrickyang) wrote on 2010-10-12:

@Jerone Young
Thinkpad Edge(Intel platform) support thinkpad-acpi and the hotkey has right function.
Thinkpad Edge (AMD platform ) still have this issue under Ubuntu 10.10

And by the way ,is there any update about this issue?

Can you pls install the kernel from http://kernel.ubuntu.com/~manjo/maveric/lp640992/

Then test your wifi key, this will case a debug message to be generated in dmesg. Please look for !!!! DEBUG ACPI, please attach this dmesg output or cut and paste that line. I need the scan code to enable the wifi hotkey.

@Manoj Iyer

I have updated the BIOS to the latest version(82ET60WW).But the WiFi hotkey remains dysfunctional.The Scancode is 5 too.
Thank you for your support.

allenlan,

Can you please try the following?

$ /lib/udev/findkeyboards

on my laptop it returns AT keyboard: input/event3

Run this next command, hit the wireless hotkey and immediately hit escape key, or else the screen will scroll too fast.

$ sudo /lib/udev/keymap -i input/event3 (replace input/event3 with what your machines returns)

On my laptop I get scan code: 0x84 key code: wlan when I hit the wlan hotkey, can you paste what your output looks like ?

From looking at the code, your scancodes that the kernel receives is correct and corresponds to KEY_WLAN, so I am afraid we will need further debugging, may be it can be fixed with udev rules.

Keng-Yu Lin (lexical) wrote on 2010-11-05:

#14

In my thinkpad, /lib/udevfindkeyboards shows:

AT keyboard: input/event3
module: input/event5

The second one is generated by thinkpad-acpi, which is what we want in this case (Manoj sorry if I gave the wrong instruction :-( ).

It may also worth to look at the value of hotkey_*_mask, the use to these masks seems to be filtering out some hotkeys.

Manoj Iyer (manjo) wrote on 2010-11-05:

#15

keng-yu no worries you were only trying to help :) I am building a kernel with some more debug messages, I will have it uploaded as soon as it is done, allenlan can you please run that kernel and update the bug with the messages it prints to dmesg?

Same location:

Keng-Yu Lin (lexical) wrote on 2010-11-05:

It interests me that in attached rfkill.txt contains no rfkill interface for wifi.

Found that /etc/acpi/events/ibm-wireless and /etc/acpi/ibm-wireless.sh also toggle wifi.
It calls toggleAllWirelessStates() in /usr/share/acpi-support/state-funcs, in which describes several sysfs nodes to look for wifi rfkill status.

Guess is good also to check if these nodes presented:

  /sys/class/net/wlan0/phy80211/rfkill*/state
  /sys/class/net/wlan0/device/rfkill/rfkill*/state
  /sys/class/net/wlan0/device/power/state
  /sys/class/net/wlan0/device/rf_kill

In ubuntu-maverick/ubuntu/rtl8192se/Makefile, CONFIG_RTL_RFKILL is not currently defined. Could be a possible solution if -D it works.

@Manoj Iyer

Hi,Manoj lyer
I run the command :$ /lib/udev/findkeyboards,
the terminal returns : AT keyboard :input/event3 module :input/event6
Then I sun :$ sudo /lib/udev/keymap -i input/event3 and hit the wifi hotkey and release.
the terminal returns: Press ESC to finish scan code:0X01 key code:esc

Is this info helpfully?

Manoj Iyer (manjo) wrote on 2010-11-09:

#18

Keyng-Yu, I think you are correct, let me enable CONFIG_RTL_RFKILL in rtl8192se driver and see if that works.

Manoj Iyer (manjo) wrote on 2010-11-09:

#19

allenlan,

RTL8192se driver was introduced as an experimental driver, the driver is not yet in the staging tree in mainline. Turning on CONFIG_RTL_RFKILL causes build failure. Also, this driver has not been updated in our kernel tree for a while. We will need support from realtek to fix any real issues with this driver source, since this is not in staging we wont be able to work out bugs in the source.

I could either update the driver source to the latest, which means you will get the new driver only in Natty (11.04) due in April 2011, or push this driver to staging and force realtek to support it.

allenlan,

OK, lets give it another try, I managed to build a kernel with RFKILL configs turned on. The kernel is available at

http://kernel.ubuntu.com/~manjo/maveric/lp640992/

Please try this kernel and report if that works for you. There are no debug messages added to this build, but if you could attach the dmesg anyway that will be great.

Manoj Iyer (manjo) wrote on 2010-11-10:

#21

allenlan,

Can you also try the kernel in http://kernel.ubuntu.com/~manjo/natty/rtl8192se/ and report if it works ok for you. This is a Natty kernel with an updated rtl8192se module, I would like to know if it works and also if it fixes your wireless hotkey issue.

dmesg.txt Edit (97.9 KiB, text/plain)

Hi,Manoj Iyer

I installed the kernel :linux-image-2.6.35-23-generic_2.6.35-23.37~lp640992manjo3_i386.deb and rebooted the system.
I am very glad that the wireless hotkey can enable and disable WiFi successfully.
But sometimes , press the wireless hotkey can mute the audio just like i pressed the audio hotkey.

I attach the output of dmesg.
Any further info you need,pls let me know,.thank you for your support.

Hi,Manoj Iyer

I tried the kernel: linux-image-2.6.37-2-generic_2.6.37-2.10~rtl8192semanjo1_i386.deb.
It seems not as good as the previous one(linux-image-2.6.35-23-generic_2.6.35-23.37).The wireless card is disabled even after installation of the driver.The wireless card is dysfunctional.
What info do you need to fix this kernel;s issue?

Thank you for your support.

Also, if this kernel does not fix the audio mute issue please open a separate bug on that one.

I tested the 'manjo4' kernel form http://kernel.ubuntu.com/~manjo/maveric/lp640992/ on a Thinkpad Edge 14 w/ the Thinkpad (Realtek) wireless. The manjo4 kernel allows the wireless hotkey to enable/disable the wireless card on this system.

SRU JUSTIFICAITON
===================
On thinkpad Edge with RTL8192SE wifi device, wifi on/off hotkey does not work. Enabled RFKILL in the rtl8192se module to enable this hotkey.

IMPACT
=======
The change is limited to Makefile, it enables -DCONFIG_RTL_RFKILL (-DCONFIG_CFG_80211 also need to be enabled as per comment in the Makefile).

TEST
=====
The new driver was tested by Steve Magoun and reported to work. Test kernel can be found in, http://kernel.ubuntu.com/~manjo/maveric/lp640992/

Hi,Manoj Iyer

I tried the kernel manjo4 on both Edge13 and Edge14(AMD platfprm),the wireless hotkey can control the Wifi.
It seems to work fine.
Can we use this kernel to pass the checkbox test?
Thank you .
