Change MATE to Xfce

There are major issues with Xorg and NVIDIA Drivers >= 495 preventing usage of the MATE Desktop. Thus it was required to switch the desktop environment to Xfce.

 In most cases when either of your server or client has a permissive firewall, the default Google STUN server configuration will work without additional configuration. However, when connecting from networks that cannot be traversed with STUN, a TURN server is required. Provide the TURN server address, port, and shared secret in order to take advantage of the TURN relay capabilities and improve connection success.
 
-An open source TURN server that can be used is [coTURN](https://github.com/coturn/coturn), and an [example container implementation](https://github.com/selkies-project/selkies-gstreamer/tree/master/addons/coturn) `ghcr.io/selkies-project/selkies-gstreamer/coturn:latest` is available. For dynamic IP addresses, [dynamic-coturn](https://github.com/mreichardt95/dynamic-coturn) is a container implementation which restarts the TURN server whenever the public IP address gets changed. [Pion TURN](https://github.com/pion/turn) is another TURN server implementation compatible with all major operating systems, and [restund](https://openwrt.org/packages/pkgdata/restund) is a TURN server implementation for OpenWRT.

 With Docker, use the `-e` option to add the `TURN_HOST`, `TURN_PORT` environment variables. You also require to provide either just `TURN_SHARED_SECRET` for time-limited shared secret TURN authentication, or both `TURN_USERNAME` and `TURN_PASSWORD` for legacy long term TURN authentication, depending on your TURN server configuration. Provide just one of these authentication methods, not both.
