Introduction

Notion is a tiling, tabbed window manager for the X window system:

  • Tiling: you divide the screen into non-overlapping 'tiles'. Every window occupies one tile, and is maximized to it
  • Tabbing: a tile may contain multiple windows - they will be 'tabbed'
  • Static: most tiled window managers are 'dynamic', meaning they automatically resize and move around tiles as windows appear and disappear. Notion, by contrast, does not automatically change the tiling. You're in control.
Features include:
  • Workspaces: each workspace has its own tiling
  • Multihead: the mod_xinerama plugin provides very nice dual-monitor support
  • RandR: mod_xrandr picks up changes in the xrandr configuration, without the need for restarting Notion
  • Extensibility: Notion can be extended with lua scripts. Browse through the scripts collection

Donations

If you'd like to support Notion, you can donate. I will not spend the donations on myself, as I wouldn't find that fair to all the other contributors. Rather I'll use the funds to cover any costs for Notion or other community projects, or pass on the donations to other organizations doing important work in the open source world.

History

Notion is a fork of Ion, which has been abandoned by its original author, Tuomo Valkonen.

Former Ion3 users will be glad to hear any changes to configuration will be backwards-compatible, so you can simply drop your ~/.ion3 tweaks into ~/.notion and rename cfg_ion.lua to cfg_notion.lua .

Changes

Changes since the original fork of Ion:

  • Handle XConfigureRequestEvent's moving transient dialogs to incorrect locations (#3167262)
  • Addition of 'lazy_resize' winprop option for applications that resize slowly
  • EMWH: always encode _NET_WM_NAME as UTF8_STRING
  • EMWH: support for _NET_ACTIVE_WINDOW
  • EMWH: fixed issue in _NET_WM_USER_TIME handling that caused new windows not to receive the focus (#3109576)
  • Fix miscalculations and infinite loops in tab width calculation
  • mod_xinerama: take into account changes to the screen topology without needing to restart Notion
  • mod_xinerama: support for overlapping screens
  • Introduce mod_xkbevents
  • mod_xrandr: introduction of a randr_screen_change_notify hook
  • Various cleanups to the build system, including improved autodetection of lua
