The difference between "-X" and "-Y" is that with "-X" the remote
host's connections to your X server are subject to X11 security
restrictions, while with "-Y" they aren't. Adding "-v" makes ssh print
debugging messages. You should run it once, to make sure "-Y" succeeds.
If you get a message such as
X11 forwarding request failed on channel 0
before ssh gives you the prompt, it didn't work, and you need to change
the sshd configuration on the remote machine. If you don't get that
message you're fine and you can forget about "-v".

(1) edit vimrc on the remote machine, and change clipboard as I
mentioned in the previous message;
(2) on the remote machine, run "xclipboard &"; this should open a small
window;
(3) on the remote machine run vim and yank a few lines; you should see
them appearing in the small window;
(4) close the small window;
(5) on the local machine, open a new terminal and run "xclipboard"; this
should open another small window;
(6) on the remote machine run vim again and yank a few lines; you should
see them again appearing in the small window.
Keep the xclipboard window open and watch it while you work. If you
see your yanks appearing there, remote transmission works, regardless of
whether you can actually paste the results on the local machine.

Failing randomly seems improbable. More likely either your yanks
get to the '*' register and they aren't transmitted over the line (only
the ones in the '+' register are sent), or your testing procedure is
flawed in other way. The definitive test is whether your yanks appear
in xclipboard.
