Multi Monitor Manager

A Linux alternative to DisplayFusion. Not affiliated with or endorsed by Binary Fortress Software.

Multi Monitor Manager is a multi-monitor toolkit for Linux X11 sessions (and X11 apps under
XWayland). Everything shown is read live from your X server.

FEATURES
• Monitor list: geometry, primary flag, physical size, DPI and refresh rate from RandR 1.5
monitors / CRTCs (Xinerama fallback) combined with Qt QScreen information; RandR output table.
• Per-monitor wallpaper: pick an image and fit mode for each monitor; the app composes ONE
spanning image and applies it with gsettings (GNOME / Ubuntu / Budgie: picture-options=spanned;
Cinnamon and MATE schemas when available on the host) and/or the X root pixmap
(XROOTPMAPID, like feh/hsetroot - for Openbox, i3, Fluxbox and other bare window managers).
KDE Plasma and XFCE manage their own wallpaper and are not changed automatically.
• Windows per monitor (EWMH NETCLIENT_LIST): move a window to the next / previous monitor
keeping its relative position, maximize a window across all monitors, center it, activate it.
• Window position profiles: save the geometry of all windows to JSON and restore them later.
• Global hotkeys (XGrabKey), configurable; combinations already taken by your desktop are reported.

LIMITATIONS
• Works on X11. In a Wayland session only X11/XWayland windows can be listed and moved;
Wayland-native windows cannot be controlled by any X11 tool.
