i am using ubuntu 16.04. The Server is also running ubuntu 16.04.

my /etc/ssh/ssh_config looks so:

Host *
#   ForwardAgent no
    ForwardX11 yes
    ForwardX11Trusted yes
#   RhostsRSAAuthentication no
#   RSAAuthentication yes
#   PasswordAuthentication yes
#   HostbasedAuthentication no
#   GSSAPIAuthentication no
#   GSSAPIDelegateCredentials no
#   GSSAPIKeyExchange no
#   GSSAPITrustDNS no
#   BatchMode no
#   CheckHostIP yes
#   AddressFamily any

#   RekeyLimit 1G 1h
    SendEnv LANG LC_*
    HashKnownHosts yes
    GSSAPIAuthentication yes
    GSSAPIDelegateCredentials no

server sshd_config:

X11Forwarding yes
X11DisplayOffset 10

When i connect to a ssh Server :

ssh -vvv -Y server

ssh connects to the server.
When i running something like xclock this happens:

debug3: receive packet: type 90
debug1: client_input_channel_open: ctype x11 rchan 2 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 59790
debug2: fd 7 setting O_NONBLOCK
debug3: fd 7 is O_NONBLOCK
debug1: channel 1: new [x11]
debug1: confirm x11
debug3: send packet: type 91

The terminal also dies after this i have to restart a new terminal.
No clock is showing up on local pc also there is no error… Any idea? When i try the same from Win 10 with xming and putty it works. Server has activated x11 forwarding.

          You need to add ForwardX11 yes to ssh-users ~/.ssh/config file

          /etc/ssh/sshd_config needs the setting X11Forwarding yes
