# Environment variables
|
||
|
|
|
||
|
|
Cage sets the following environment variables:
|
||
|
|
|
||
|
|
* `DISPLAY`: if compiled with Xwayland support, this will be set to the name of
|
||
|
|
the X display used for Xwayland.
|
||
|
|
* `WAYLAND_DISPLAY`: specifies the name of the Wayland display that Cage is
|
||
|
|
running on.
|
||
|
|
|
||
|
|
The following environment variables can be used to configure behavior of
|
||
|
|
libraries that Cage uses. Effectively, these environment variables configure
|
||
|
|
the Cage session.
