I had a similar issue today. I was using the phone to listen to music with headphones (walking to work, just to set the scene).
I unplugged the headphones when I reached the office, did my usual pre- work faff of making a cup of tea etc. When I went to use the device the screen would turn on but I couldn't enter my passcode into the lock screen. Had to hold the power button to do ao hard reboot. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1373641 Title: sometimes unresponsive shell after idle Status in unity8 package in Ubuntu: Confirmed Bug description: mako r51 (rtm) <jdstrand> kgunn: so, phone is in my pocket for a while. I pull it out. I press the power button. I can swipe the screen and unlock but I can't open the launcher, switch applications, etc (it happened to me 3 times while I was out) <kgunn> jdstrand: mmm....sounds different, like the shell died <jdstrand> I do see the hint that the launcher is there-- when I unlock, it opens slightly then hides I think I saw that... phone is working ok atm jdstrand: did it "recover" on its own ? like...you couldn't use spread...and then 30 secs later you could? <jdstrand> kgunn: I let it sit for maybe 10 minutes. I had to hard reboot by long pressing the power button. when confirmation came up to poweroff, it wouldn't respond. so I had to hold the power button for a long time to force it off <jdstrand> kgunn: I had been living with this for a couple of weeks nad it was very frustrating-- then I saw that bug about input that was on the list (kgunn pretty sure this means bug 1295623 ) , subscribed to it, and it seemed fixed when it hit the images. I don't know if it is related, or luck, or what :) kgunn: note, I could interact with the foreground app To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1373641/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
