[Software] Virtual Keyboard at SDDM Login Screen

[Snowhog]

The button is present, but clicking on it does nothing. Is Virtual Keyboard only supported on a Touch Screen devices? I've Googled on this, and tried the several 'fixes', none of which resulted in bringing up a Virtual Keyboard on the SDDM Login Screen. I don't need one, but it would be nice, given the button is presented, if it actually worked.

I could swear I answered this here recently, but it must have been Reddit or KDE's forum, maybe.

For a Kb in SDDM you need qt6-virtualkeyboard-plugin, dunno why it is missing - the same thing happens in 25.10.

Once Kubuntu replaces SDDM with the new plasmalogin, iirc the also-new Plasma keyboard should work there, as well as on the desktop.

My apt reports that qt6-virtualkeyboard-plugin is already at the newest version, so it is installed, but I still don't get a virtual keyboard when clicking on the button. Any other thoughts? This is my laptop.

Hmmm lemme look. I don't have it on a laptop but I did get it to work on my PC, or a VM, at login, let me double check. The PC is tied up for a bit ripping DVDs

On Kubuntu/Plasma 6,the SDDM virtual keyboard situation is currently a bit messy...

Check whether SDDM is configured to use Qt Virtual Keyboard

sudo nano /etc/sddm.conf.d/virtualkbd.conf

add

[General]
InputMethod=qtvirtualkeyboard

reboot

Make sure the plugin actually exists where SDDM expects it

find /usr -name libqtvirtualkeyboardplugin.so 2>/dev/null

If nothing is returned, the plugin package may be incomplete or broken despite apt saying it is installed
if so then try reinstalling the package

sudo apt install --reinstall qt6-virtualkeyboard-plugin
