The gap
Even moderately basic desktop use needs keys like Ctrl, Alt, Tab, Super, and the arrow
keys, especially for terminals, shortcuts, and window navigation. The on-screen-keyboards
shipped by KDE Plasma and GNOME do not include that full set.
Onboard supports this style of fuller
keyboard layout, but it does not work on Wayland.
The answer
Vboard provides a lightweight, always-accessible keyboard with persistent appearance
settings, optional word suggestions, tray support, and a uinput-based input
backend built for modern GNU/Linux desktops. It has native Wayland support on KDE
Plasma and works on GNOME using Xwayland where needed.
Ideal for
Touchscreen devices, kiosks, accessibility workflows, and systems whose physical
keyboards are missing, damaged, or simply inconvenient.
