Not sure what has changed.  I've been successful at this many time in
the past. 

My method:
 1. Login into client under username whatever
 2. Run startx
 3. Open xterm
 4. ssh to server
 5. Run su (the exact invocation would be helpful)
 6. try to run vim


grep -E 'X|Root' /etc/ssh/*config From the remote system:
/etc/ssh/ssh_config:   ForwardX11 no
/etc/ssh/sshd_config:PermitRootLogin no 
/etc/ssh/sshd_config:X11Forwarding yes
/etc/ssh/sshd_config:X11DisplayOffset 10

grep -E 'X|Root' /etc/ssh/*config From the local system:
/etc/ssh/ssh_config:   ForwardX11 yes
/etc/ssh/sshd_config:# This sshd was compiled with PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
/etc/ssh/sshd_config:PermitRootLogin yes
/etc/ssh/sshd_config:#ForwardX11 yes
/etc/ssh/sshd_config:X11Forwarding yes
/etc/ssh/sshd_config:X11DisplayOffset 10
