@Rightaway I am using the Sway window manager on the Framework Laptop 12. My config files for Sway are here.
This is a good point.
As far as I know, Sway and Niri use the Swaylock as a lock screen application by default. But I haven’t found the way to use the virtual keyboard wvkbd on the swaylock’s lockscreen. So, I opened the issue ticket for the Swaylock project below.
I investigated below. According to the Reddit threads, the gtklock can work to display a virtual keyboard. And the swaylock-mobile may also work for that.
