So I've also seen this symptom on my everyday phone (rtm/mako). It's
not due to a large wallpaper image, as I use the stock one. But it does
seem to happen when the phone's been running for a long time. So maybe
high memory use? And the symptom is that I press the power button to
turn the scree
I reproduced with the following steps:
0. The device must be unplugged from usb or power supply and connected to a
wifi network.
1. open the network indicator
2. Switch wifi off from the indicator
3. Immediately suspend the device with the power button before the device
switches to cellular data
Ooh, jibel, will try that in a sec. Wanted to write down the results of
my "walking around Boston for a bit" strategy first.
Two makos:
- MakoA with ubuntu-touch/ubuntu-rtm/14.09-proposed 160 (i.e. 20150112). Has
a cellular plan but no data.
- MakoB with ubuntu-touch/stable 13 (i.e. 20150109)
jibel, I've not been able to reproduce your way yet, on my MakoB.
Seeing what happens when the wifi changes over to 3G (looks like a bit
of churn in the indicators and over dbus that add to system load), are
you sure that you're seeing comment-20-style recovery? (i.e. first
power button doesn't tu
I'm seeing comment-18-style recovery but with the default wallpaper.
This is on krillin #191 with 2 SIM cards.

@John, I'm not convinced that bug 1398782 is a dup. It may have some
similar behavior (a power dialog appearing) but this bug here isn't
about a crash or incoming calls.

It seems to be due to a greeter.showNow() call that takes a long time to
return, delaying the handling of the power button release, which would
stop the dialog from appearing. Investigating exactly why that call
takes a while.

In my experience, this was because we load the greeter synchronously,
blocking handling of the power-release event. If loading the greeter
took longer than 2s, the dialog would come up because it never saw the
power-release event. And often loading the background image could slow
that down enough
OK, so that branch fixes one instance of the problem.

I've added some debugging code to my unity8 and here's the output from
when I just saw this happen:

I thought I mentioned in comment #7 that I had already debugged this to
that point. The delay is happening in the handling of the power down-
press. The call to greeter.show() is synchronous, and Qt seems to block
handling of the power-up event until the show() call (and thus the
