Thanks everyone, but I still get the same error.  On the client I
added to /etc/ssh/ssh_config:

Host *
ForwardAgent yes
ForwardX11 yes

and I deleted ~/.Xauthority and ~/.ICEauthority.  On the server I
added to /etc/ssh/sshd_config:

X11Forwarding yes

and restarted sshd.  I get:

$ ssh -Y 192.168.10.1
The authenticity of host '192.168.10.1 (192.168.10.1)' can't be established.
RSA key fingerprint is.
Are you sure you want to continue connecting (yes/no)? yes
Failed to add the host to the list of known hosts
(/home/grant/.ssh/known_hosts).
Password:
Warning: No xauth data; using fake authentication data for X11 forwarding.

Should I reboot?
