+⚠️ **Issue with X on Ubuntu 20.04 and Unprivileged**
+
+If you really need to use Ubuntu below 22.04 there is an issue with access rights that prevents Xorg from starting on TTY7 on an Unprivileged container. Workaround exists but a change on the host machine is required so please accept the risk beforehand. On host execute:
+```yaml
+chmod 660 /dev/tty7
+```
