Frequently Asked Questions

How do I do a particular thing with cagebreak?

How do I remap Caps Lock?

Remapping Caps Lock globally seems to be the best option. Follow instructions here to achieve this (should be roughly distribution-agnostic).

What do I do if Cagebreak does not work with the current wlroots version?

You can probably downgrade wlroots with

$ pacman -U /var/cache/pacman/pkg/old-version

If you have cleared your package cache, see instructions in the ArchWiki.

Cagebreak should start working again after the downgrade.

After a new release, the downgrading will no longer be necessary (in fact, downgrading will probably break your setup).

How do I get firefox to run under wayland?

Set the following environment variables

  • MOZ_USE_WAYLAND=1
  • GDK_BACKEND=wayland

to activate wayland support for firefox.

How do I get firefox to screenshare properly?

Execute the following commands with the appropriate env vars:

export XDG_SESSION_TYPE=wayland
export XDG_CURRENT_DESKTOP=sway
/usr/lib/xdg-desktop-portal -r
/usr/lib/xdg-desktop-portal-wlr

How do I map characters which are not on the Keyboard?

Suppose you want to use a command like bind for a character which is likely not on your keyboard like "ы" - you should write it as "Cyrillic_yeru".

These names can be obtained by running xev and pressing the respective key(s) (combinations).

How do I change the size of the cursor?

The size and shape of the cursor is determined by the application, however, most applications respect the environment variables XCURSOR_SIZE and XCURSOR_THEME

To change the cursor size, one could use:

export XCURSOR_SIZE=1

If you are using an application which inherits its environment variables from something outside the scope of the export (such as a daemon for emacs might), you can usually specify your environment variables in the applications respective configuration.

How is Cagebreak launched?

The documentation says to start Cagebreak like any other binary.

If you want to start Cagebreak on login, you can use your shells equivalent of a .bash_profile. In BASH appending cagebreak (given that it is installed in the path) to .bash_profile is fine.

If you want to start Cagebreak using systemd you could use a service started on user login, though the development team once ran into some issues with permissions for the services.

Please note that Cagebreak does not solve the problem of locking the screen or login in general.

How are applications launched in Cagebreak?

There are multiple ways to launch external programs in cagebreak.

  • Using a terminal emulator is a perfectly valid way to launch applications. If you want to be able to close the terminal you used to start the program, you may use &disown, which should be available in every shell.
  • Using the exec command in the cagebreak config, it is possible to launch programs when cagebreak is started. Moreover, as this command can be combined with commands such as bind, it can be used to create custom keybindings which execute external programs. (See also the man page cagebreak-config).
  • All commands mentioned previously are also available over the socket which allows the creation of (arbitrary) keybindings on the fly and a fortiori keybindings running arbitrary commands.
