AFAIK pitti is our master of the HAL, reassigning ...

I only maintain the HAL script for the printers which is part of hal-cups-utils.

Hey Motin, thanks for discovering this! Do you know what the visible effect of that is? I take it that it breaks your particular type of killswitch? (I remember that more general bug a few days ago).

Can you please do "lshal > /tmp/hal.txt" and attach that here, as a reference? Thank you!

Fixed in Karmic branch. I'll do the Jaunty SRU once I get some more information from Fredrik, see comment 3.

This bug was fixed in the package hal - 0.5.12~rc1+git20090406.46dc48-2ubuntu2

    handling, thanks to Fredrik Motin! (LP: #368553)

Setting to incomplete until information from comment 3 arrives.

Anyone who is affected by this who could give some further information about this problem?

Attaching lshal output.

I've noticed this typo on my Dell XPS M1330 running Jaunty after a system crash. The system became unresponsive after Gimp asked to allocate memory for a 400+Mb file. Then applets (NM and blueman installed from PPA) start crashing and I had to kill X with magic SysRq and reboot.

For reference this is what was in my .xsession-errors file:

Atany, does it break your killswitch on your system?

Martin, it worked fine some time before, but now it is not. I'm not sure when exactly it stopped working as I rarely turn off wi-fi.
Switching off wireless disconnects from the network, but NM still constantly tries to connect to the network.

Attached is an obvious patch which fixes the issue.

Ah, so it is a regression then. Would you be able to test a package in jaunty-proposed?

Yes, I have jaunty-proposed enabled and can test a package once the update is available.
Currently, the only available version of hal is 0.5.12~rc1+git20090403-0ubuntu1. I'm running amd64.

Hey, I haven't been in to check in here for a while. The visible result was that before the fix, the wireless would not activate itself automatically after switching on and off the killswitch. It didn't fix the issue of activating if the killswitch was enabled before suspend, though. But one less regression is good as well.

Attaching hal.txt, though it should be identical to the one attached above from an XPS 1330.

Uploaded, waiting for Steve or Colin to process.

Accepted into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Thanks for fixing the issue.

With the latest update in proposed the killswitch on my system (Dell XPS M1330, Jaunty amd64) works fine, no errors reported and the wireless is deactivated and activated automatically when switching killswitch off and on.

Though, as Motin already mentioned, if killswitch is turned on while the laptop is suspended the Network Manager reports 'device not ready' after wake up despite the wireless interface is working (as reported by iwconfig/iwlist utilities). Restarting the Network Manager helps in this case. But I think this is not directly related to the issue tracked here and a new bug report should probably be opened.

This bug was fixed in the package hal - 0.5.12~rc1+git20090403-0ubuntu3

  * 87_standalone_smbios.patch: Fix typos which caused Dell wifi killswitches
    to not work any more. (LP: #368553)

 -- Martin Pitt <email address hidden> Thu, 11 Jun 2009 13:54:34 +0200

Martin:

After installing this latest patch, my WiFi STOPPED working, saying something like
"iwlagn: rfkill switch must be turned off" in dmesg (alltough the rfkill switch definitely is ON)

I am sorry but cannot reproduce the correct message, since I reinstalled the whole system from scratch and applied all the available updates one by one in order to isolate the problem. My situation is as follows:
I installed Ubuntu Jaunty (64bit) from the live cd on a brand new Dell Vostro 1520.
Everything worked fine, including WiFi. Then I applied all available updates, and after rebooting, the wireless access did not work anymore.

So I decided to reinstall the system again and applying updates one by one. Now I have applied all of them (with wifi still working), except the following:
hal
libhal-storage1
libhal1

The currently installed version is 0.5.12~rc1+git20090403-0ubuntu1, the updated version would be 0.5.12~rc1+git20090403-0ubuntu3 for those 3 packages. If you can you point me to the source repository or to a description of the changes made, I could try to fix the problem and tell you what was wrong with the update.

One final question: is there any possibility to "revert back" from an updated package to an earlier version?

Gerhard,

I have submitted a bug report for the same problem you have encountered and can also confirm the problem lies with the last update to hal.

You can force a specific version in synaptic using the ctrl-e key on the specific package. It will provide you with a dropdown list of the two availables choices (ubuntu 1 and ubuntu3).

Hope this helps.

Hello Gerhard,

You mean the switch is off, and wifi should be on? What happens if you
switch it the other way round?

The patch is attached to this bug, and the full package change is

http://launchpadlibrarian.net/27776744/hal_0.5.12%7Erc1%2Bgit20090403-0ubuntu2_0.5.12%7Erc1%2Bgit20090403-0ubuntu3.diff.gz

It only changed the shell script which gets installed as
/usr/lib/hal/scripts/hal-system-killswitch-get-power-linux, so if you
want to hack on this, you don't even need to change packages, you can
just edit it inline.

Thanks for having a look!

> One final question: is there any possibility to "revert back" from an

Yes. You could e. g. downgrade hal to the jaunty final version with

  sudo apt-get install hal/jaunty

The other packages like libhal* can stay updated.

Hello Martin,

the problem seems to be as follows: after your corrections the script finally works. Before, it always yielded an exit code != 0, because of the syntax errors.

Now, I tracked down the problem by printing more logs. It turns out, that

hal-system-smbios --st_wlan

always yields "1" as the result, regardless of the position of the rfkill switch. Thus, the script always exits with 0, which apparently is wrong.

I confirm the comment by Gerhard that

sudo /usr/lib/hal/hal-system-smbios --st_wlan

returns always 1, irrespective of the position of thh rfkill switch.

Other users affected,
http://ubuntuforums.org/showthread.php?p=7549951#post7549951

Added report ""hal-system-smbios --st_wlan" reports rfkill switch always on, nm-applet always disabled (wireless, dell laptops)",
https://bugs.edge.launchpad.net/ubuntu/+source/hal/+bug/394663
on this issue.

This issue about the typo has been fixed, exposing the bug in hal-system-smbios.

This is just to confirm that on DELL 1720 the patch does not work. I reverted back to hal - 0.5.12~rc1+git20090403-0ubuntu2 for now. hal - 0.5.12~rc1+git20090403-0ubuntu3 is still nuking the WIFI. I am just a regular end user and not able to provide any other specific bug details other than that I have been very very frustrated over the past week. But if you post some instructions regarding what you want to see from my config I shall be happy to do so.

Same problem here. Dell Vostro 1520 with ubuntu 9.04 amd64

After hal update "0.5.12~rc1+git20090403-0ubuntu3" my wifi stopped working.
Solved downgrading to "0.5.12~rc1+git20090403-0ubuntu1".

With the downgrade Network-manager still shows wifi networks after switching off but can't connect. Switching on again everything works perfect.

With latest update "hal-0.5.12 -XXXX-ubuntu3" killswitch don't do anything (only leds turn on and off)

If I can do anything to help, contact me!

Thanks for spotting. So it seems that the "wwan" side of the fix was confirmed to work, but we should disable the "wlan" bit again, since it causes this regression.

I apologize for this regression, it's unfortunate that this didn't turn up during testing -proposed.

Mario, subscribing you FYI. It seems that the st_wlan counterpart of the previous standalone app doesn't work. However, apparently the killswitch worked fine before, so perhaps these models were already handled by the kernel's rfkill framework. I'm going to disable this part for now.

Ah, using bug 394663 for tracking the regression fix instead.
