Hybrid laptop's accelerometer tilt interpreted as WiFi hardware switch

[Adam Colligan]

This bug appears to be a regression in Vivid sometime in the second half of March 2015.

When the machine is tilted (e.g., onto its side), Syslog reports an "unknown" button being pressed. When tilted back to the normal laptop position, the machine's WiFi disconnects and is shown as disabled in the connection manager. Syslog indicates that urfkill registered a hardware switch cutoff for the WiFi.

I know that the accelerometers do work in other contexts and can be read properly in Ubuntu. As an example, this "orient" script works for me: https://github.com/leszakk/orient .

Hardware: HP Envy x360 15t -- this is a hybrid touch notebook
OS: Ubuntu 15.04 Beta 2 -- Desktop version
Kernel: 3.19.0-10-generic
urfkill:
  Installed: 0.6.0~20150318.103828.5539c0d.1-0ubuntu1
  Candidate: 0.6.0~20150318.103828.5539c0d.1-0ubuntu1
  Version table:
 *** 0.6.0~20150318.103828.5539c0d.1-0ubuntu1 0

Below is a Syslog readout from a test event. The notebook starts in normal typing position, the hinge bent at a right angle. At 16:13:30, without moving the hinge, I tip the notebook 90 degrees to the left from my perspective. So the Unity launcher is now closest to the floor, for example. I hold it there for about 10 seconds until 16:13:40.

I can guarantee rendering to the screen (Compiz) has no effect on how input devices get interpreted by the system, even if it complains about receiving unknown configuration change requests from somewhere as a result.

Marking bug as Invalid for Compiz.

[Adam Colligan (adam-p)]

Update: this bug also appears if the screen is held level in a normal, vertical position and the keyboard hinge is rotated around it. If I swing the keyboard under and around the screen into tablet mode, then swing it back into laptop mode, WiFi is disabled and has to be manually re-enabled via Network Manager.

[Dave Gilbert (ubuntu-treblig)]

I'm tempted to think this is a bug either in the kernel, X or the input handling - because it seems more to do with what the interpretation of key input (that happens to be how the accelerator signals?) than actual actions. What happens if you try booting with 14.10 kernel but leave everything else the same?

[Adam Colligan (adam-p)]

Tested 3.16.0-29 . Bug behavior appeared to be the same.

It might also be worth noting that sometimes, even when I re-enable WiFi, the network manager does not recognize available networks. However, I can connect if I choose to connect to a hidden network and then select from a list of potential hidden networks one that I know is active and in range. After that successful connection, network manager begins displaying that and other networks properly. I have assumed that this is just to do with the messy way in which the OS thinks the WiFi has been turned on or off by hardware switch, but maybe it's some kind of clue by itself.

[Adam Colligan (adam-p)]

I am currently working around the problem by setting key control to false in /etc/urfkill/urfkill.conf .

[Adam Colligan (adam-p)]

I can confirm this behavior recurred in a fresh install of Ubuntu 16.04 on this same machine.

Antoine Monmayrant, can you file a separate bug report? That will collect more accurate information for your machine.
