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

[Michael Terry (mterry)]

Looks like the tutorial thinks its on a phone instead of a desktop. It's supposed to skip that screen on the desktop. I'm guessing at one point you changed the windowed mode to be staged or something?

I'll look at if we can be cleverer.

[Ramil Minnigaliev (thunderamur)]

Yes, I tried to switch to phone mode. But, what do I do now?

[Michael Terry (mterry)]

To work around this bug, enter the following in a console:

sudo gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts/UserXXX --method org.freedesktop.DBus.Properties.Set com.canonical.unity.AccountsService demo-edges '<false>'

Where XXX is your UID (the number given when you type "id -u").

[Michael Terry (mterry)]

Hrm. So to reproduce, install unity8 on the desktop and then:

1) sudo gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts/User1000 --method org.freedesktop.DBus.Properties.Set com.canonical.unity.AccountsService demo-edges '<true>'
2) gsettings set com.canonical.Unity8 usage-mode Staged

(Replace 1000 in step #1 with your UID.)

The problem is that the tutorial is thus fooled about what mode we're running in (it thinks tablet/phone).

The left-edge tutorial bits assume a touch screen. And they don't run in desktop mode (when there is at least one pointer). So everything *should* work, except that usage-mode was overridden.

I think since we no longer treat the gsettings value as a user-setting (unity8 will override it at will), we should re-evaluate it on startup. That should avoid this particular scenario.

[Ramil Minnigaliev (thunderamur)]

Michael Terry (mterry), thanks, tutorial is gone.

[Daniel van Vugt (vanvugt)]

I think that status is incorrect. The fix isn't yet in any of:
   https://launchpad.net/ubuntu/+source/unity8
Is it?

I only point this out as another duplicate came in over the weekend and it would be easier to de-duplicate bugs if we didn't close them prematurely.

[Ahmed Hosny (ahmed-hosny-badr)]

So, Where can I get those fixes which should been released time ago ?
I'm on Ubuntu 16.04 64 bit, and still don't have the fix.

[Michael Terry (mterry)]

Daniel, this fix did land. If we're experiencing the same symptoms again, it might be best to use a new bug indeed. Might be a different root cause.

[Daniel van Vugt (vanvugt)]

Correct. And I'm not trying to be pedantic but this is confusing people.

The fix landed in lp:unity8 revision 2329 on 15 April. So that's 'Fix Committed'.

What's wrong is to say 'Fix Released' in Ubuntu, because I just downloaded the latest unity8 source code for Ubuntu (8.12+16.04.20160401-0ubuntu1):
   https://launchpad.net/ubuntu/+source/unity8
and the fix is not in 'Ubuntu' yet. Not 'Fix Released'.

[Michael Terry (mterry)]

Ah I understand what you mean. It's Fix-Released for the overlay, but not the distro side of things yet. Which is what the ubuntu bug tasks track. For the overlay, we'd more properly use an Ubuntu RTM task. Though we rarely bother these days.

Once we land silos in yakkety (and copy overlay packages into yakkety), this will be Fix-Released for Ubuntu proper as well.
