[emulator] unity8 fails to start since image 152 (mako 149).

[Ricardo Salveti]

Unity8 fails to start on emulator (tested on x86).

Wizard works fine, but after complete it, screen stays black.

Checking via adb shell, unity8 is running but nothing showing up at the screen.

Follows the unity8 log:

Quite a few things changed on 149, so not clear yet on the issue: http://people.canonical.com/~lzemczak/landing-team/149.commitlog

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Tim Peeters (tpeeters)]

PageHeadSections is relatively new (added last week) and should be part of the ubuntu-ui-toolkit-theme package. Are you importing Ubuntu.Components 1.1 or an older version?

[Tim Peeters (tpeeters)]

correction: PageHeadSections is part of qtdeclarative5-ubuntu-ui-toolkit-plugin (not the theme as I said in the previous comment).

[Ricardo Salveti (rsalveti)]

Did push the a new sync for latest ui-toolkit, let's check this bug again after it lands.

[Zoltan Balogh (bzoltan)]

I have created a new emulator from the image version #157 and confirmed that the Shell does not show up.

Logged in to the eulator and enabled the utopic-proposed repository.

After rebooting the emulator the shell comes up.

[Martin Pitt (pitti)]

Many thanks for the fast fix! Much appreciated to unbreak the emulator.

[Martin Pitt (pitti)]

This doesn't yet seem to be in image 157, and image 160 crashes at boot due to bug 1349709.

[Martin Pitt (pitti)]

I confirm that upgrading image 157 to current utopic fixes that problem. I still happens after rebooting again (forcefully).

In general, unity and the launcher are still very unstable. E. g. after launching calculator there is no way to get out of it again -- the launcher (swipe from left edge) doesn't come up, nor does the "swipe across screen" gesture works. This is potentially a different bug, though.

[Ricardo Salveti (rsalveti)]

Tested with image 160 and it finally worked as we expect.

It seems wizard is crashing sometimes, but I'm still investigating that one.

pitti, I'm able to swipe back to the main screen just fine here (and also access the launcher). Just make sure you start the swipe movement from the first valid screen pixel, not the emulator gray border.
