[wizard] on the security page, there's a long delay until the keyboard appears

[Leo Arias]

On the security page of the wizard, if you select passphrase and click on the text field, the on-screen keyboard can take up to 5 seconds to appear.

On krillin, it happens for me for any language. On mako, if I select english first then the keyboard appears immediately. If I select spanish, it's slow. If then I select english again, it's still slow. So if you have problems reproducing this, just set the spanish language.

settings are not responsible for the osk slowness

[Bill Filler (bfiller)]

my guess would be maliit-server is not started when the wizard starts or it's starting then crashing
could you verify by doing a ps if maliit-server is running when you tap in the entry field? and after the keyboard shows up if the maliit-server process is the same?

[Leo Arias (elopio)]

I found this:
maliit-server is not running on the welcome page.
when I go to the security page, maliit is started.
I clicked the text field, and the keyboard appeared quickly. It could be because I spent some time on the terminal checking for the process. maliit has the same pid. Maybe I was just lucky this time.
I hit back to go to the welcome page. Same maliit process running.
I hit continue. A new maliit process is started.
Touch the text field. A new maliit process is started. It took a long time for the keyboard to appear.

I couldn't find crash files, but I'm not sure if I was looking at the right place. I'll attach my maliit log.

Bill told me to do this:
1) reboot so the wizard appears 2) before maliit-server is started do this from a terminal a) ulimit -c unlimited b) export MALIIT_DEBUG=true c) start maliit-server

I got the attached core file.

The maliit-server is being explicitly stopped and restarted by the welcome wizard when the language is changed (along with the indicators) to ensure that they start with the correct environment variables (see: http://bazaar.launchpad.net/~system-settings-touch/ubuntu-system-settings/trunk/view/head:/wizard/ubuntu-system-settings-wizard-set-lang.conf ). The delay in keyboard start-up is caused by QML compilation of the keyboard layouts, so this should be improved when the QML caching lands.

The only other thing I can think of that we could potentially do to improve this would be to add some signal that the wizard could send to the keyboard for it to change its current locale without being restarted, this would allow the keyboard to be started slightly sooner (on the language page) and then not restarted, I'm not sure how necessary this will be after the caching has landed though?

The branch https://code.launchpad.net/~mterry/ubuntu-system-settings/wizard-refresh-take-6/+merge/235720 will help this in two ways:

1) In set-lang.conf, we not only stop maliit, but also immediately restart it. So it has a little longer to come up before the user notices.
2) The first security page will no longer have a text field, but just something the user clicks. This will also give the OSK longer to come up before the user notices.

So this may become less of an issue once that lands.

[Leo Arias (elopio)]

From what Michael Sheldon said, I would just like to say that there is also a long delay without changing the language.

[Michael Sheldon (michael-sheldon)]

Leo - The maliit-server doesn't get started until the first input request is made, so there will be a delay whether a language is changed or not (but there will be subsequent delays every time a language is changed). Once the welcome wizard is modified to start the maliit-server after the language selection is complete (instead of waiting for an input request) this should be reduced.

[Leo Arias (elopio)]

Got it.
Just a heads up that I added this bug to the readiness report send by Julien every week.

[Sebastien Bacher (seb128)]

the wizard has been moved to the unity8 source, reassigning

[Michał Sawicz (saviq)]

Is this still an issue? Maliit should be started with the wizard now, potentially restarted on language change.

[Leo Arias (elopio)]

Yes, it is still slow to appear. I tested in krillin vivid 141.

[Lukáš Tinkl (lukas-kde)]

This should be fixed by the new OOBE wizard.
