I've added a patch to the upstream bug report of bug #1572331 that
seems to solve the scaling issue. Waiting for feedback.
I then tested delaying Onboard's launch in unity-greeter:

The scaling issue seems to be a Gtk problem. I've opened a bug report here
https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1572331
A workaround for that in Onboard wouldn't be pretty.
I have yet to figure out why the keyboard becomes all black, and not
just half the size.

Yes, that was the hint I needed, thanks. It's an issue with the window scaling
factor. I wasn't aware of unity-settings-daemon changing it. That should
explain the 500ms delay too. Onboard probably starts up with scaling-factor 1

This worked for me, however, the keyboard only covered the upper left
quarter of the black box.

Thanks for the log. It's recreated on each reboot, so I only see the one

Here is a screen capture of the new behavior. Onboard now displays the

It includes multiple reboots. The first batch of reboots is *PRE*

Thank you both. There's no obvious error or traceback in the logs. I'd
still like to see Asvin's x-0-greeter.log, but at the moment it doesn't

being started at all, but this seems to be the normal case.
