[Bug 1562734] Re: Onboard keyboard shows black box on login

[marmuta]

The keyboard seems to go below the screen, that's why we see a black
rectangle there. On my 1920x1200 screen, scaled to 960x600, it
apparently ends up at y=750.

See attachment for the configure events.  Case 1) is the black rectangle
case. The values are all over the place. GdkEventConfigure doesn't agree
with get_pos()/get_size() and neither are fully correct. At the moment I
don't see how I could compensate for that in Onboard. AFAIKT the problem
is with Gtk, not Onboard.

It might be possible for unity-greeter to help, however. If the greater
delays Onboard's launch until after unity-settings-daemon is done with
setting the scaling factor, we get to Case 2) and see at least the
half/quarter sized keyboard. If/when bug #1572331 is fixed it would
hopefully go back to normal size.

As the worst case, the DPI dependent scaling in u-s-d would have to be
turned off until Gtk is ready for it.
