Why go left

LeftWM is a tiling window manager written in [Rust] that aims to be stable and performant. LeftWM is LeftWM follows the following mantra:

LeftWM is not a compositor.
LeftWM is not a lock screen.
LeftWM is not a bar. But, there are lots of good bars out there. With themes, picking one is as simple as setting a symlink.

Because you probably want more than just a black screen, LeftWM is built around the concept of themes. With themes, you can choose between different bars, compositors, backgrounds, colors, docks, and whatever else makes you happy.

LeftWM was built from the very beginning to support multiple screens and ultrawide monitors. The default keybindings support ultrawide monitors and multiple screens.

One of the core concepts/features of LeftWM is theming

With LeftWM, there are two types of configuration files:

Dependencies

While LeftWM has very few dependencies, this isn't always the case for themes. Themes typically require the following to be installed. However, this is up to the author of the theme and could be different.

List of LeftWM dependencies:

List of common dependencies for themes:

| Dependency
(git) | Ubuntu 20.4.1
sudo apt install {} | Arch
sudo pacman -S {} | Fedora 33
sudo dnf install {} | PKGS | |--------------------------|-----------|-------------------|-----------|--------------------------| | feh | feh | feh | feh | feh | | compton | compton | paru -S picom* | compton | compton | | picom | manual * | picom | picom | picom | | polybar | manual * | paru -S polybar* | polybar | polybar | | xmobar | xmobar | xmobar | xmobar | xmobar | | lemonbar | lemonbar | paru -S lemonbar* | manual ** | lemonbar | | conky | conky | conky | conky | conky | | dmenu | dmenu | dmenu | dmenu | dmenu |

* You can use whichever AUR wrapper you like. See [paru] and [yay].
** See the git page (link in first column) for how to install these manually

Installation (with package manager)

Gentoo ([GURU])

sh sudo layman -a guru && sudo emerge --sync sudo emerge --ask --verbose x11-wm/leftwm

Archlinux ([AUR])

sh paru -S leftwm

[paru] is an AUR helper like [yay], but written in [Rust].

Fedora ([copr])

sh sudo dnf copr enable atim/leftwm -y && sudo dnf install leftwm

NetBSD ([Official repositories])

sh pkgin install leftwm

or, if you prefer to build it from source

sh cd /usr/pkgsrc/wm/leftwm make install

Void ([XBPS])

sh sudo xbps-install -S leftwm

Cargo ([crates.io])

sh cargo install leftwm

If you install LeftWM with crates.io, you will need to link to the xsession desktop file if you want to be able to login to LeftWM from a display manager (GDM, SSDM, LightDM, etc.):

sh sudo cp PATH_TO_LEFTWM/leftwm.desktop /usr/share/xsessions

Manual Installation (no package manager)

Using a graphical login such as LightDM, GDM, LXDM, and others

  1. Dependencies: Rust, Cargo
  2. Clone the repository and cd into the directory

    bash git clone https://github.com/leftwm/leftwm.git cd leftwm

  3. Build leftwm

    bash cargo build --release

  4. Copy leftwm executables to the /usr/bin folder

    bash sudo install -s -Dm755 ./target/release/leftwm ./target/release/leftwm-worker ./target/release/leftwm-state ./target/release/leftwm-check ./target/release/leftwm-command -t /usr/bin

  5. Copy leftwm.desktop to xsessions folder

    bash sudo cp leftwm.desktop /usr/share/xsessions/

You should now see LeftWM in your list of available window managers. At this point, expect only a simple black screen on login. For a more customized look, install a theme.

Optional Development Installation

If your goal is to continuously build leftwm and keep up to date with the latest releases, you may prefer to symlink the leftwm executables instead of copying them. If you choose to install this way, make sure you do not move the build directory as it will break your installation.

  1. Dependencies: Rust, Cargo
  2. Clone the repository and cd into the directory

    bash git clone https://github.com/leftwm/leftwm.git cd leftwm

  3. Build leftwm

    ```bash

    Without systemd logging

    cargo build --release

    OR with systemd logging (view with 'journalctl -f -t leftwm-worker')

    cargo build --release --features=journald ```

  4. Create the symlinks

    bash sudo ln -s "$(pwd)"/target/release/leftwm /usr/bin/leftwm sudo ln -s "$(pwd)"/target/release/leftwm-worker /usr/bin/leftwm-worker sudo ln -s "$(pwd)"/target/release/leftwm-state /usr/bin/leftwm-state sudo ln -s "$(pwd)"/target/release/leftwm-check /usr/bin/leftwm-check sudo ln -s "$(pwd)"/target/release/leftwm-command /usr/bin/leftwm-command

  5. Copy leftwm.desktop to xsessions folder

    bash sudo cp leftwm.desktop /usr/share/xsessions/

You should now see LeftWM in your list of available window managers. At this point, expect only a simple black screen on login. For a more customized look, install a theme.

Rebuilding the development installation

  1. Now if you want to get the newest version of leftwm run this command from your build directory:

    bash git pull origin main

  2. Build leftwm

    ```bash

    Without systemd logging

    cargo build --release

    OR with systemd logging (view with 'journalctl -f -t leftwm-worker')

    cargo build --release --features=journald ```

  3. And press the following keybind to reload leftwm

    bash Mod + Shift + R

Using the Makefile

For conveniece we also have a Makefile with the following rules:

|make ... | info | | - | - | |all | implies build and test | |test | runs same tests as CI on github | | build | builds with cargo flag --release | | clean | clean all buildfiles | | install | install by copying binaries to /usr/bin, also places leftwm.desktop file to /usr/shar/xsession and cleans build files | | install-dev | installs by symlinking, copies leftwm.desktop, no clean | | uninstall | removes leftwm-* files from /usr/bin and leftwm.desktop file |

Starting with startx or a login such as slim

Make sure this is at the end of your .xinitrc file:

```bash

.xinitrc

exec dbus-launch leftwm ```

Theming

If you want to see more than a black screen when you login, select a theme:

With LeftWM-Theme

bash leftwm-theme update leftwm-theme install NAME_OF_THEME_YOU_LIKE leftwm-theme apply NAME_OF_THEME_YOU_LIKE

Without LeftWM-Theme

bash mkdir -p ~/.config/leftwm/themes cd ~/.config/leftwm/themes ln -s PATH_TO_THE_THEME_YOU_LIKE current

LeftWM comes packaged with a couple of default themes. There is also a community repository for sharing themes.

For more information about themes check out our theme guide or the [wiki].

Configuring

The settings file to change key bindings and the default mod key can be found at

bash ~/.config/leftwm/config.toml

the file is automatically generated when leftwm or leftwm-check is run for the first time.

Default keys

| Keybinding | Description | |---------------------|------------------------------------------------------------------------| | Mod + (1-9) | Switch to a desktop/tag | | Mod + Shift + (1-9) | Move the focused window to desktop/tag | | Mod + W | Switch the desktops for each screen. Desktops [1][2] changes to [2][1] | | Mod + Shift + W | Move window to the other desktop | | Mod + (⬆️⬇️) | Focus on the different windows in the current workspace | | Mod + Shift + (⬆️⬇️) | Move the different windows in the current workspace | | Mod + Enter | Move selected window to the top of the stack in the current workspace | | Mod + Ctrl + (⬆️⬇️) | Switch between different layouts | | Mod + Shift + (⬅➡) | Switch between different workspaces | | Mod + Shift + Enter | Open a terminal | | Mod + Ctrl + L | Lock the screen | | Mod + Shift + X | Exit LeftWM | | Mod + Shift + Q | Close the current window | | Mod + Shift + R | Reload LeftWM and its config | | Mod + p | Use dmenu to start application |

Note: Although we encourage you to use Alacritty, LeftWM will set your default terminal to the first terminal it finds in this list (in the order presented):

  1. Alacritty
  2. Termite
  3. Kitty
  4. URXVT
  5. RXVT
  6. ST
  7. ROXTerm
  8. Eterm
  9. XTerm
  10. Terminator
  11. Terminology
  12. Gnome Terminal
  13. XFCE4 Terminal
  14. Konsole
  15. UXTerm
  16. Guake

Floating Windows

You can optionally switch between tiling or floating mode for any window.

| Keybinding | Description | |-------------------------|-----------------------------------------| | Mod + MouseDrag | Switch a tiled window to floating mode | | Mod + RightMouseDrag | Resize a window | | Drag window onto a tile | Switch a floating window to tiling mode | | Mod + Shift + (1-9) | Switch a floating window to tiling mode |

Workspaces

By default, workspaces have a one-to-one relationship with screens, but this is configurable. There are many reasons you might want to change this, but the main reason is for ultrawide monitors. You might want to have two or even three workspaces on a single screen.

Here is an example config changing the way workspaces are defined (~/.config/leftwm/config.toml)


NOTE The line workspaces = [] needs to be removed or commented out if a configuration like the following example is used.


```toml [[workspaces]] y = 0 x = 0 height = 1440 width = 1720

[[workspaces]] y = 0 x = 1720 height = 1440 width = 1720 ```

You may optionally specify an ID for your defined workspaces. This is helpful if you want to assign different gutter settings to each workspace in your theme.

```toml [[workspaces]] y = 0 x = 1720 height = 1440 width = 1720 id = 1

[[workspaces]] y = 0 x = 0 height = 1440 width = 1720 id = 0 ```


NOTE You do not have to define an ID for each workspace, but if you assign an ID to one workspace all subsequently defined workspaces without an ID will be assigned an ID incrementing from the largest ID currently assigned to any workspace. In the above example if the second workspace was not defined with ID = 0 it would be assigned ID = 2. Keep this in mind when creating or customizing themes.


Tags / Desktops

The default tags are 1-9. They can be renamed in the config file by setting the list of tags.

Here is an example config changing the list of available tags. NOTE: tag navigation (Mod + #) doesn't change based on the name of the tag.

toml tags = ["Web", "Code", "Shell", "Music", "Connect"]

Layouts

By default, all layouts are enabled. There are a lot of layouts so you might want to consider only enabling the ones you use. To do this add a layout section to your config.toml file. This enables only the layouts you specify.

Example:

toml layouts = ["MainAndHorizontalStack", "GridHorizontal", "Fibonacci", "EvenVertical", "EvenHorizontal", "CenterMain", "CenterMainFluid"]

Layouts may also be specified on individual workspaces, this is useful if you have monitors with different aspect ratios or orientation.

Example:

```toml [[workspaces]] id = 0 x = 0 y = 480 width = 3840 height = 1600 layouts = ["CenterMain", "CenterMainBalanced", "EvenHorizontal"]

[[workspaces]] id = 1 x = 3840 y = 0 width = 1440 height = 2560 layouts = ["MainAndHorizontalStack", "EvenVertical"] ```

NOTE When defining layouts per workspace, you will need to define workspace IDs explicitely.

More detailed configuration information can be found in the Wiki.

LeftWM is EWMH compliant

The default layouts are all of the kinds described by the Layout enum.

Troubleshooting

| Issue | Description | Solution | |-|-|:-:| | LeftWM not listed by login manager | You likely need to add the xsessions file to the right folder. | See installation | | No config.toml file exists | LeftWM does not always ship with a config.toml. You will need to execute LeftWM at least once for one to be generated. | Try the following: leftwm-worker | | Config.toml is not being parsed | LeftWM ships with a binary called leftwm-check. It might not be installed by the AUR. | Try the following: leftwm-check | | Keybinding doesn't work | It's likely you need to specify a value or have a typo. | See Wiki |
