Using Steam's keyboard in a custom Wayland session

Onboard is old news.

If you want to run Steam’s keyboard in your own Linux distribution on Wayland you need to have ibus running.

<span style="color:#323232;">/usr/bin/ibus-daemon -d -r --panel=disable --emoji-extension=disable
</span>

Maybe you can also set some env variables to make it appear automatically. I’ll have to test how that clashes with KDE’s own virtual keyboard handling.

These are the variables I found:

<span style="color:#323232;"># Set input method modules for Qt/GTK that will show the Steam keyboard
</span><span style="color:#323232;">export QT_IM_MODULE=steam
</span><span style="color:#323232;">export GTK_IM_MODULE=Steam
</span>

For more goodies look in /usr/bin/gamescope-session. It starts steam with everything needed to work on the Deck.
