onboard doesn't show on lock screen in 11.10 beta 2

I'm adding an upstream task because I'd like to see the developer's opinion on how this should be fixed. Do we need onboard 0.96 to get the gtk3 version?

XEmbed mode is supposed to work in the current release. The gtk3 changes aren't required yet, not for this bug at least. I'm looking into it.

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

I should have remembered. The keys to enable embedding in gnome-screensaver have moved from gconf to gsettings. The gtk3 changes in upstream take care of that, but the current release still sets them in gconf.

Chadmerkert, as a workaround try running these in a terminal:

gsettings set org.gnome.desktop.screensaver embedded-keyboard-enabled true
gsettings set org.gnome.desktop.screensaver embedded-keyboard-command 'onboard --xid'

I suspect this will make it work, if not, please let me know.

The workaround works great! Onboard now shows up when the screen is locked!

I also realized that I can't get onboard to work at the GDM login screen. I switched from lightdm to GDM, but there isn't an option for on onscreen keyboard. I have set /apps/gdm/simple-greeter/accessibility/screen_keyboard_enabled in gconf-editor, but that doesn't help. Is this a problem with onboard or GDM? Any idea on how to get onboard on the GDM login? My GDM version is:
gdm:
  Installed: 3.0.4-0ubuntu11
  Candidate: 3.0.4-0ubuntu11
  Version table:
 *** 3.0.4-0ubuntu11 0
        500 http://us.archive.ubuntu.com/ubuntu/ oneiric/universe amd64 Packages
        100 /var/lib/dpkg/status

Thanks.

I'm not sure what happens with onboard in GDM. As far as I know gnome-shell will have a built-in on-screen keyboard and thus onboard might be replaced in GDM too. Jeremy could probably tell you more about this.
If you still want to try, playing with or creating /usr/share/gdm/autostart/LoginWindow/onboard.desktop may be the way to go.

Lightdm has an option to start onboard now, only the actual typing isn't working yet. There is a fix on it's way apparently with unity-greeter-0.0.9. It's not in the repos yet though.

I don't think GDM 3.0 supports an on screen keyboard; you'll need to use LightDM (which is the new Ubuntu default as it's far more powerful for our use cases & it's supposed to be more themable too). For Ubuntu 12.04, GDM 3.2 or 3.4 will probably have the GNOME Shell screen keyboard built-in.

Hello chadmerkert, or anyone else affected,

Accepted onboard into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

yes, this works, but the checkbox isn't selected by default to show on the lock screen

> but the checkbox isn't selected by default to show on the lock screen
I've added this recently, should come with the bug fix release.
Onboard then silently sets those g-s-s keys on startup, but does so only if no other osk has taken them before.

@Francesco, just in case, this needs xembed-onboard = True in onboard-defaults.conf, but you knew this.

marmuta, what exactly needs to be set for the lock screen to work? Is it gsettings, lightdm.conf, some other file?

I'd like to test what circumstances the onscreen keyboard still won't show on the lock screen, because it should always show if org.gnome.desktop.a11y.applications screen-keyboard-enabled is turned on.

@Jeremy

You should open the Onboard Preferences and activate the checkbox "Show Onboard when unlocking the screen".

The keys are in gsettings, at org.gnome.desktop.screensaver. To have Onboard show up when unlocking the screen they need to be set to
embedded-keyboard-command = 'onboard --xid'
embedded-keyboard-enabled = True

The lightdm greeter (unity-greeter) has "onboard --xid" hard-coded into the greeter code. I believe there's nothing to configure (yet).

Onboard can set the screen-saver keys on user action, as Francesco wrote above, or automatically and silently on startup (since 0.96.1).
The latter requires to have
xembed-onboard = True
in onboard-defaults.conf. 'xembed-onboard' is the key behind the checkbox in preferences. Basically this enables the toggle by default. Francesco has added this to the patch for the Ubuntu package.

This is not a 100% solution though. If Onboard has never been run before, it won't show up in the unlock screen either.
Also, if any other on-screen keyboard has set itself to be the unlock keyboard, Onboard won't stay silent, but pop up one of two message boxes asking the user what to do. It's a bit like the default web browser setting. it wouldn't be polite to set it silently in this case.

For testing, you could do
gsettings reset-recursively apps.onboard
gsettings reset-recursively org.gnome.desktop.screensaver
then run (Ubuntu's) onboard once and lock the screen -> it should show the keyboard

Or, to simulate some other app grabbing the unlock keys
gsettings set org.gnome.desktop.screensaver embedded-keyboard-command 'some-other-osk'
running onboard should then pop up a message box to either overwrite the setting or disable the checkbox in Onboard's preferences.

Another solution may be to have a gsettings vendor override file for gnome-screen-saver. That way Onboard wouldn't need to run once to have lock screen working. I don't believe this should be installed by Onboard though, pretty sure not by the upstream version and probably neither with an Ubuntu patch.

Anyway, I believe it would be named
/usr/share/glib-2.0/schemas/org.gnome.gnome-screenshot.gschema.override

and look like this
[org.gnome.desktop.screensaver]
embedded-keyboard-command='onboard --xid'
embedded-keyboard-enabled=true

Works as intended on my fresh install. The toggle in preferences does turn it on and off in the unlock screen. Also Onboard shows up there right after its first launch.

Once it's in there, it doesn't go away on its own though. It's still in the lock screen when I turn off the osk in universal access settings. It can be turned off manually in preferences, but perhaps ultimately something other than Onboard should toggle the gsettings key "embedded-keyboard-enabled" in sync with "screen-keyboard-enabled"?
