I think this might be related to the phone powering on the screen after a notification. That is: I believe the occurrence is higher after the phone has woken the screen (and perhaps then timed out), compared to when there was no notification since I last used it. This is because it seems to affect me more when I'm responding to something (eg. notification LED with screen off) versus when I have taken the initiative to use my phone.
I also haven't seen this since OTA-7, where other bugs related to screen power seem to have been fixed. -- 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.
