I did some more testing, trying to reproduce this. I did my usual "get dbus-daemon to go crazy because I'm running through a bunch of wifi networks" test in my neighborhood.
After getting my phone to be a bit overloaded, I still couldn't trigger this bug even once. But I did notice one oddity -- sometimes the phone screen wouldn't finish fading in to full brightness. It would then go to full brightness if I touched the screen. But that made me think that there is some mechanism/bug by which the fade-in early-exits. So what if this bug is an immediate early-exit to the fade? Then second press is actually accurately received as a turn- off-screen-please request (which flashes the screen to full brightness for a moment). And the third is a normal turn-on-request. Pure conjecture without much evidence. Just a thought. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to powerd in Ubuntu. https://bugs.launchpad.net/bugs/1429887 Title: Sometimes need 3 power button presses to turn on screen Status in Canonical System Image: Incomplete Status in Unity System Compositor: New Status in powerd package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: [filing here although may be other components] Mako running 211 from rtm I experienced these symptoms which have been previously mitigated in other scenarios. Last week while traveling and roaming this happened pretty much 100% of the time. This occurred in all areas (hotel, MWC, outside, etc) Press power button, no response Press button again, screen turns on for a few seconds then turns off Press button again, either phone resumes or more often the power dialog is shown When I returned back home the function was normal without reboot or other changes. The differences in environment: Roaming on foreign GSM network Lots of Wifi APs not connected Attached are some perhaps relevant logs, unfortunately the syslog rolled.
