Hello.
I need to virtual keyboard on login screen, I added InputMethod=qtvirtualkeyboard to /etc/sddm.conf then virtual keyboard is appears, but input not working - I can click on keys, but there are no chars in password field.
Its not working on login screen but working fine on Lock screen.

Im try:
reinstall qtvirtualkeyboard, sddm, plasma-desktop, libibus.
clear /var/lib/sddm.
copy sddm and X11 configs from fresh installation.

Any ideas?

Thanks.

Its seems to be a problem with dual screens config.
qtvirtualkeyboard works on the second screen but not on the first.

I have set InputMethod=qtvirtualkeyboard in:
/usr/lib/sddm/sddm.conf.d
/etc/sddm.conf.d
/etc/sddm.conf

But nothing changed.

Log just say:
sddm-greeter: input method is not set

to make virtual keyboard appears, you have to set edit field focused… so firstly to click inside the field and next click virtual keyboard button
