Multi Monitor Bar for GNOME Shell

Add full panels, overview, and mirrored indicators to every monitor.

GNOME Extensions · GitHub · Donate

An updated fork of spin83/multi-monitors-add-on with modern GNOME Shell support (45 – 49), mirrored indicators, screenshot tool cloning, Blur my Shell integration, and more.

GNOME Shell: 45, 46, 47, 48, 49

Tested on:

• Fedora 43 — GNOME 49

The included script copies everything to the extensions directory, compiles schemas, and enables the extension in one step:

chmod +x reinstall.sh
./reinstall.sh

1. Copy the extension folder:

   cp -r . ~/.local/share/gnome-shell/extensions/multi-monitors-bar@frederykabryan

2. Compile schemas:

   glib-compile-schemas ~/.local/share/gnome-shell/extensions/multi-monitors-bar@frederykabryan/schemas/

3. Restart GNOME Shell (see note above).

4. Enable:

   gnome-extensions enable multi-monitors-bar@frederykabryan

Open preferences through the Extensions app (click the ⚙️ icon next to Multi Monitor Bar) or via command line:

gnome-extensions prefs multi-monitors-bar@frederykabryan

Open Panel icons by monitor in the extension preferences. Each connected display gets its own checklist: Main monitor, Extended 1, Extended 2, and so on. Check or uncheck an icon to change that panel immediately. Choices are saved across restarts, and the list updates when monitors or extensions change. Extended panels require Show Panel to be enabled. Only extensions with panel indicators appear in these lists.

Hiding an icon on the main monitor still lets you display it on extended monitors. Per-monitor choices override the existing Activities, AppMenu, and DateTime switches for that monitor. Enable the extension to see the connected monitors and available panel icons in preferences.

Build the upload archive with bash package.sh. It includes runtime JavaScript, metadata, styles, the license, and schema XML. Compiled schemas are excluded; GNOME Shell 45+ compiles them during installation.

After modifying the source:

1. Run the reinstall script (or copy files manually):

   ./reinstall.sh

2. On Wayland, log out / log back in. On X11, press Alt+F2 → r.
3. Watch logs for errors:

   journalctl -f -o cat /usr/bin/gnome-shell
