Using on Hyprland (Ubuntu 24.04 LTS)

Enable OpenBangla Keyboard with IBus on Hyprland (Ubuntu 24.04 LTS)

Overview

This guide sets up the OpenBangla keyboard input using IBus on Hyprland Wayland compositor.
Works across native and Flatpak apps and persists after reboot.

---

Steps

1. Install IBus and OpenBangla

IBus:

sudo apt install ibus

Open-Bangla Keyboard: OpenBangla Installation Reference

bash -c "$(wget -q https://raw.githubusercontent.com/OpenBangla/OpenBangla-Keyboard/master/tools/install.sh -O -)"

2. Clean Hyprland config

Edit ~/.config/hypr/hyprland.conf and remove or comment out:

• Any input { kb_layout = ... } blocks
• Any exec-once lines that start ibus-daemon or set input-related env vars

---

3. Create systemd user service for IBus

Create the service file:

mkdir -p ~/.config/systemd/user
nano ~/.config/systemd/user/ibus-daemon.service

Paste:

[Unit]
Description=IBus Daemon (Hyprland)
After=graphical-session.target hyprland-session.target
Wants=hyprland-session.target

[Service]
ExecStart=/bin/sh -c 'sleep 2 && dbus-update-activation-environment --systemd DISPLAY WAYLAND_DISPLAY XDG_CURRENT_DESKTOP GTK_IM_MODULE QT_IM_MODULE XMODIFIERS && /usr/bin/ibus-daemon -rx'
Restart=always
Environment=DISPLAY=:1
Environment=WAYLAND_DISPLAY=wayland-1
Environment=XDG_CURRENT_DESKTOP=Hyprland
Environment=GTK_IM_MODULE=ibus
Environment=QT_IM_MODULE=ibus
Environment=XMODIFIERS=@im=ibus

[Install]
WantedBy=default.target

Replace DISPLAY and WAYLAND_DISPLAY with your actual values:

echo $DISPLAY
echo $WAYLAND_DISPLAY

Enable and start the service:

systemctl --user daemon-reexec
systemctl --user daemon-reload
systemctl --user enable --now ibus-daemon.service

---

4. Set input method environment variables globally

Create:

mkdir -p ~/.config/environment.d
nano ~/.config/environment.d/99-ibus.conf

Add:

GTK_IM_MODULE=ibus
QT_IM_MODULE=ibus
XMODIFIERS=@im=ibus

Logout and login (or reboot) to apply.

---

5. Add OpenBangla keyboard in IBus

Run:

ibus-setup

• Add OpenBangla Keyboard and your default English layout
• Set your preferred shortcut to switch input (e.g., Ctrl+Space)

---

6. Enable IBus in Flatpak apps

Run these commands:

flatpak override --user --env=GTK_IM_MODULE=ibus
flatpak override --user --env=QT_IM_MODULE=ibus
flatpak override --user --env=XMODIFIERS=@im=ibus
flatpak override --user --talk-name=org.freedesktop.IBus

---

7. Test everything

Open apps like gedit, Chrome, Telegram (Flatpak).
Switch input with your shortcut and type Bangla text (e.g., typing ami should output আমি).

---

Notes

• sleep 2 in systemd service delays start to avoid race conditions
• dbus-update-activation-environment syncs environment for Wayland
• Always verify your DISPLAY and WAYLAND_DISPLAY variables with:

echo $DISPLAY
echo $WAYLAND_DISPLAY

---

Done! You should now have fully working OpenBangla input on Hyprland with Ubuntu 24.04 LTS.
