Full screen keyboard covers the greeter with Maui theme

[antonio-rojas]

When using the default (Maui) theme and having qtvirtualkeyboard installed, the user is unexpectedly presented with a full screen keyboard at startup, without any user interaction. You have to manually hide the keyboard to see the greeter, which can be difficult to figure out.

Edit: This happens with any of the themes shipped by sddm. Only breeze works fine, since it provides a button to hide/show the virtual keyboard

SDDM 0.17.0
Qt 5.9.3

Maybe QT_IM_MODULE should be opt-in for sddm themes? (instead of installations)

Gentoo was hit by this, and is currently removing qtvirtualkeyboard from the config file at installation as a workaround (gentoo/gentoo@9cb1894):

sed -i -e "/^InputMethod/s/qtvirtualkeyboard//" "${D}"/etc/sddm.conf

Kde Neon LTS User Edition has this virtual keyboard too.
Kde Neon User Edition work fine.

According to the Qt Virtual Keyboard deployment guide, additional effort in the QML is required in order to make it work. I understand why it's showing in full screen because it does the same in any QML app that has not instantiated an InputPanel.

Until the themes are implementing the needed bits, I'd suggest to revert the change that is setting the environment variable.
