Bug Description

SRU Justification [precise]:

Impact: Prevents using WiFi without Bluetooth, or vice-versa.
Fix: Patch adds two Dell laptop models to rfkill blacklist table; affects only those models.
Testcase: Disable Bluetooth via the indicator icon; verify that WiFi continues to operate.

This patch is being carried in quantal as UBUNTU SAUCE (commit 318d5bb).

-----

In oneiric (and daily kernel) there seems to be a bug in dell-laptop.

When you kill dell-bluetooth, it also hard blocks 'Wireless LAN'.
This should NOT be the case and only block your bluetooth.

Seth Forshee (sforshee) wrote on 2011-12-07:

It looks like this issue is kind of nasty. The interface used by dell-laptop involves using an SMI to tell the BIOS to disable the radio, and what the BIOS does in response is completely opaque to us. The functionality for this in dell-laptop seems to be based upon similar functionality in the Dell-provided libsmbios software, and it looks to match what's provided there.

So my expectation at this point is that we're unlikely to get this fixed unless we can get information from Dell about what's happening. There are a couple of things you can try though.

First, check for a BIOS update for your machine. It's possible that this is a bug in the BIOS that's been fixed.

Second, install the smbios-utils package and try playing with smbios-wireless-ctl, using --bt=0 to disable bluetooth and --bt=1 to enable it. See if you observe similar changes in the status of the phy0 switch. If you don't then there may be something that the tool is doing that dell-laptop is not.

Seems to be broken with smbios-wireless-ctl also :(

Seth Forshee (sforshee) wrote on 2011-12-08:

That's what I suspected, unfortunately.

There's no bug tracker for libsmbios, but there is a mailing list. It doesn't appear to have had much activity recently, but you could try reporting the bug there. If the list proves unresponsive there are some email addresses in the libsmbios source we could try. If we can get a fix for libsmbios then we can apply the same fix to dell-laptop. I don't see how we'll be able to fix this without some help from Dell.

The problem can be cured on the Dell XPS 13z (and maybe the XPS 15z also?) by removing the dell_laptop driver with "sudo rmmod dell_laptop", or by adding the model to the driver's rfkill blacklist table.

Mario Limonciello from Dell has supplied the attached patch, which adds the XPS 13z to the rfkill blacklist table.

Does removing the dell_laptop driver also fix it for the XPS 15z? (If so, that model could also be added to the blacklist table). Would someone with a 15z kindly try "sudo rmmod dell_laptop" and report back?

Removed the dell_laptop module on my XPS L502X, and this works as expected.
So it seems like blacklisting this model will also fix the issue!

Thanks Jean-Louis.

I have extended the dell_laptop rfkill blacklist patch to include the Dell XPS 15z as well as the XPS 13z (revised patch attached for reference), and produced a test PPA kernel with the patch applied. Jean-Louis or other 15z owners, please apply this PPA then reboot, and confirm that it fixes the problem: https://launchpad.net/~kamalmostafa/+archive/dellxps

I will test this later tonigh.
But some small thing:

.ident = "Dell XPS 15z",

The Dell XPS 15z is a different model
L502X != 15z

I can confirm the kernel in your PPA fixes my issue.
rfkill doesn't show the dell devices anymore, and bluetooth and wireless can be disabled now without killing each other :)

@Kamal thanks! there's also another bug with this Dell laptop: when you turn it on the wifi is always "disabled by hardware switch" (the wifi led is off). When I boot Windows it does "remember" the state of wifi when it was turned off. Same happens with screen bright (it is always maximum no matter how it was when you turned off). Should I file another bug for it?

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-26.41). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

@Fuad- Yes, you should file a new bug for each separate problem you encounter, after searching to see if it has been reported already. For what its worth, on my Dell XPS13z with the fixed kernel (comment #17), my system does correctly "remember" the wifi switch state after a reboot. But as you noted, the screen backlight brightness does not get preserved -- I believe that issue is very common, not specific to just the Dell XPS models.

Sorry, but not working here. If you play with it a little you can check this out: when you turn on wifi via hardware the wifi is ok but not bluetooth; then you open bluetooth settings and it turns on, but then if you turn off everything goes down.

Also, if you turn on wifi via "hardware switch", then disable via software, the led goes off, like and you cannot connect bluetooth anymore; you need to enable it via hardware again...

I'm not sure what is the supposed behavior of it under subsequent calls of hard blocking and soft blocking, but i seems a little inconsistent. When you soft block it, you have to unlock it via hardware, that doesn't seem to be the wanted behavior.

Is there any log or information I can provide for help?
