Last I checked, it was working fine in firefox and chrome for my Chromebook, either Kubuntu 23.04 or Neon, or both. I am running Fedora atm, as it has audio support ootb for my specific hardware. Maliit is not working well, if at all, there.
I imagine you may need some extra configuration for this in Arch, making sure it is actually running in Wayland proper, etc.
Before I installed Fcitx5, Maliit worked with Konsole, but not with Firefox; After installing Fcitx, it no longer works, even if I quit Fcitx. (Above was tested after changing the virtual keyboard setting to Maliit and rebooted)
I’m using Plasma on archlinux with wayland and so I’m “forced” to use maliit, which seems a deaad project (no commit since March 2023).
I would like, if possible, to have by Plasma mantainers their point of view about the virtual keyboard status expecially due to the fact that valid alternatives (onborad and squeekboard are not supported by plasma under wayland)
corekeyboard neither, which was very good. In fact its dev had to say:
We thought about that, but wayland keyboard will only work in a specific wayland compositor, like if we based our keyboard on wlroots than corekeyborad will not work on gnome or KDE.
so we didn’t focused on that.
