 |
|
Hello,
Main information
If you have a builtin-wlan adapter in your notebook and you want a daemon handling your wlan button to modprobe/rmmod your card without being logged in at a console nor a X11, you may go on reading this. This daemon replaces any hotkey manager (for the wlan task).
Download and installation instructions
I have searched for some months for a howto or something else how to get my wlan adapter (mini pci) turned on or off by pressing the corresponding button. I found rfswitch.sourceforge.net on the web and tested the listed kernel modules (most are included into portage), but I did not get positive results.
After a while I tried it again and with the acerhk module my button produced scancode events for the first time. Unfortunatly the events were not handled and therefor I planed to write a little application running as a daemon.
You can get it here at http://www.roessner-net.com/wlan_button/
Download the latest wlan_button-*.tar.bz2 archive. Put the wlan_button.init script into /etc/init.d/ and rename it to wlan_button. Put wlan_button.conf as wlan_button into /etc.conf.d/ as well.
| Code: |
Run make and make install (as root)
|
To get the application work, you must include the event interface into the kernel:
| Code: |
Device Drivers -> Input device support -> Event interface
|
Now try to find a kernel module which enables the wlan button events. Look at http://rfswitch.sourceforge.net/
In my case (MaxData 8000x) I needed acerhk (Look into portage). I must give modprobe some arguments:
| Code: |
modprobe acerhk usedritek=1 autowlan=1 force_series=290
|
I got these from a developer from rfswitch. Maybe you will find more information on the acerhk homepage.
After finding the right module, you may have to setup some keycodes
Press your button twice and have a look at dmesg. You may find things like atkdb.c ...setkeycodes e070 <keycode>
In my case:
| Code: |
/usr/bin/setkeycodes e070 184
/usr/bin/setkeycodes e071 185
|
Put them into /etc/conf.d/local/start. Now run
UPDATE since v1.50
The following instructions have been changed. So please have a look at the main project page.
Deprecated
| Code: |
wlan_button -u -1 -d -1 -D
and press your wlan button twice. Put these hex values into the config file (It is documented. Have a look into it).
Last but not least:
rc-update add wlan_button default
Start the daemon and be happy.
I tested this aplication on three notebooks with different hardware (ipw2100 and ndiswrapper).

Wow, this looks great! I don't have a notebook ATM available for testing, but if this really works well, should be added to the gentoo baselayout.

Thanks. Unfortunatly I do not get very much responds to this article nor from the rsfwitch guys, so I do not really know if people would like this. From my point of view this little tool stops stupid console commands.
What´s up folks

Most laptops, the wireless button generates an acpi event.
So all you ahve to do is write a small ACPI script the looks for the wlan device in the /sys filesystem if it isn't there then modprobe the modules and bring the device up, if the location is there then just rmmod the modules in the correct order and the device is down.
Then sounds much easier then what you have done with all the setkeys and such.
To see if your generates an even run | Code: | | tail -f /var/log/acpid |
then press the button if it logs something write down the button infomration and then edit your apci scripts accordingly.
P.S. I am not at my laptop right now, nor will I be here soon, if you want to scripts I have then let me know and I will get them up here asap

And that is exactly the problem. My button is not supported via acpi. And it is a HW button. I know that this sound a little bit harder but it is working now (after a very long period).
I think, that your tip migth be very good in cases where people have a SW switch. |

I have released a new version 1.30. You can go to the project website and get an ebuild for it. Please read the README file. The ebuild may have bugs, so a feedback is welcome. Thanks in advance

| This sounds like exactly what I've been looking for. I'll have to try it out when I get home tonight. |

I have a short question:
My friend uses ndiswrapper (instead of the rtl8180 native). His wlan is working fine. Unfortunatly he can not rmmod the ndiswrapper module. Just after unloading it, something, maybe udev is loading the module again. By killing udevd, this stops for a few moments.
We have started the notebook and looked, if the module was started at boot time. But this is not the case. First after modprobing it once, the system does not stop re-loading it after rmmod. So my tool wlan_button has no chance to do its job.
Does someone have an idea?
Thanks
Christian
N.B.: version 2.01 is out for some days now. You can get the ebuild and two further files in bugzilla. |

Hy!
Have a problem with your ebuild. Downloaded it from bugzilla, downloaded conf and init and placed them into the directories. Then I've tried
emerge wlan-button-2.22
-->
Calculating Dependencies
!!! Problem in null/wlan-button-2.22 dependencies.
!!! "Specific key requires an operator (null/wlan-button-2.22) (try adding an '=') exceptions
What have I done wrong?
Das war der Part für die mitlesenden. Direkte Antwort im Forum wäre schön, aber noch besser wäre per ICQ 101826903 oder phoenix [at] lanon.net
Danke vielmals |

Tach,
you placed wlan-button-2.22.ebuild inside of a folder named wlan-button and the init file (all other files have been marked as obsolete, please ensure, you grabbed the right ones) into the files folder?
Should look something like this. Please have a look at app-laptop in the path
| Code: |
/usr/local/portage/app-laptop/wlan-button/wlan-button-2.22.ebuild
/usr/local/portage/app-laptop/wlan-button/files/wlan-button.init
|
Have you done a
| Code: |
ebuild /path/to/overlay/app-laptop/wlan-button/wlan-button-2.22.ebuild digest
|
Did it download the bz2-Tarball?
Now this should work. Maybe I forgot to say that you need the folder app-laptop.
Christian

Hello..first of all sorry for my english...
I've been having troubles with my Acer Aspire 3002LCI. I'm using ndiswrapper for my wlan card and it was working perfectly a week ago. Now when the system starts up the radio is always off. I've to press the led/button of the wireless card (it is in the front panel of the laptop) a few times to get it to work and it's a pain in the ass. So I find your programm but I can't compile it:
| Code: |
gcc -pthread `xml2-config --libs` -lsysfs -o wlan-button wlan-button.o xmlparseconfig.o
wlan-button.o(.text+0x570): In function `get_sysfs_attr_value':

collect2: ld returned 1 exit status

Any ideas? |

Thanks in advance

N.B.:I just pasted a new ebuild, version 2.23 |

I have noticed that some people do hae these build problems, where libsysfs is not linkable. I really do not know why this bug occurs. I have asked some friends to test this and they even did not have any problems. But all of them me including are using completly ~x86 systems, so it might be a different gcc and/or binutils package.
So I feel sorry, I am not able to give an anser but everyone else is much welcome to help me answering this.
Thanks in advance
