# RDP backend
* *WLR_RDP_TLS_CERT_PATH*: required when using `wlr_backend_autocreate`,
specifies the path to the TLS certificate to use for encrypting connections
* *WLR_RDP_TLS_KEY_PATH*: required when using `wlr_backend_autocreate`,
specifies the path to the TLS private key to use for encrypting connections
* *WLR_RDP_ADDRESS*: the IP address to bind to, defaults to `127.0.0.1`
* *WLR_RDP_PORT*: the port to bind to, defaults to 3389.
Note: a TLS certificate and key can be generated like so:
```
$ openssl genrsa -out tls.key 2048
$ openssl req -new -key tls.key -out tls.csr
$ openssl x509 -req -days 365 -signkey tls.key -in tls.csr -out tls.crt
```
`tls.csr` can be discarded. Connecting to the RDP backend with xfreedrp can be
done like so:
xfreerdp -v localhost --bpp 32 --size 1920x1080 --rfx
# Wayland backend # Wayland backend
* *WLR_WL_OUTPUTS*: when using the wayland backend specifies the number of outputs * *WLR_WL_OUTPUTS*: when using the wayland backend specifies the number of outputs
