Here's a backtrace of unity-system-compositor! :) I have qtcore, qtdeclarative and libunity debug packages installed.
Moreover, I installed the following packages as suggested by kgunn: libmirserver33-dbgsym libmirclient9-dbgsym libmircommon5-dbgsym libmirplatform9-dbgsym libmirprotobuf1-dbgsym mir-client-platform-android3-dbgsym NOTE: when I first tried to take the bt, the compositor had PID 1574. I attached gdb to it, and while it was loading the dbgsyms I think the compositor died. I checked top, compositor now had PID 1575. UI still frozen, power button still not responding. I attached gdb to it again, and got the bt that you can find attached. ** Attachment added: "unity-system-compositor BT" https://bugs.launchpad.net/canonical-devices-system-image/+bug/1491566/+attachment/4470669/+files/unity-system-compositor_STUCK -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1491566 Title: unresponsive shell including power button doesn't blank/unblank display Status in Canonical System Image: In Progress Status in Mir: In Progress Status in unity-system-compositor package in Ubuntu: In Progress Bug description: Note: based on descriptions we spawned bug 1495871 to cover cases where the power button still works, this bug will only be for cases where the ui input is frozen as well as the power button being unresponsive RC proposed MX4 r100 This happened twice in the last two days Receive an incoming text Screen turns on and notification is shown notification goes away try to interact with the phone and nothing works another text message is received and the notification is displayed Adding incoming calls as also suspected to be triggering the issue Note this has been impossible to reproduce, and in use only happens very rarely To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1491566/+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
