Title:
unity8 sometimes hangs on boot
Status in unity8 package in Ubuntu:
In Progress
Bug description:
The following gdbus call is failing with a "Error: Timeout was
reached" message:
gdbus call --session --dest com.canonical.UnityGreeter --object-path /
--method org.freedesktop.DBus.Properties.Get
com.canonical.UnityGreeter IsActive
This is being seen on krillin devices starting with image 106 from ubuntu-touch/devel-proposed. It doesn't happen every time, so far today, I've seen it 3 times from about 12 tests. On the most recent failure, I grabbed a console and tried repeatedly to run the command from the shell, even after 2 hours the timeout was still being returned (after about 28 seconds).
A copy of ~/.cache/upstart/unity8.log is here:
http://paste.ubuntu.com/10179482/
I have 3 test cases where the problem was observed:
http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-qtchooser/1/console
http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-gsettings-ubuntu-touch-schemas/1/console
http://d-jenkins.ubuntu-ci:8080/job/fjg-boottest/3/console
In all cases, the test is using adt-run (from autopkgtest) to drive a
test on the phone device. adt-run uses the above gdbus call to
determine if the desktop is active. In all the examples, the device
was freshly flashed.
