This is confusing Robert, is your target system running Debian Bullseye? There is no Debian release called Bullet. Do you have any custom configuration in the server or client side? Please provide more information, for instance detailed steps, so we can attempt to reproduce it.

I control these from home using Ubuntu 21.10 presently. Until recently, X-forwarding has worked from all but ancient Redhat 6.2 servers. I recently upgraded my debian shell server to Bullet, and after the upgrade ssh -X debian.eskimo.com from my workstation nanook.eskimo.com ceased to function. It simply says "Cannot open DISPLAY". At the time, all the others continued to work. Today, when I went to do upgrades, now ssh -X is forwarding across the board to all flavors of Linux. I did an ssh -V, nothing obvious wrong in the connection. debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering public key: /home/nanook/.ssh/id_rsa RSA SHA256:a5bReJXl7L91eGOuCYugHsY2rn2a0WTDXEBTC93YdmA agent debug1: Server accepts key: /home/nanook/.ssh/id_rsa RSA SHA256:a5bReJXl7L91eGOuCYugHsY2rn2a0WTDXEBTC93YdmA agent debug1: Authentication succeeded (publickey).
