Can't launch x11 remotely from terminal

After I installed OS X Lion I haven't been able to launch x11 remotely (using ssh) from Terminal.

It works fine locally, and also remotely directly from the Xterm.

I log in to the unix server at my university from the terminal like this:

ssh -l -X login@host.com

This used to launch x11 and allowed me to run applications such as nedit from the unix server, but this does not work on Lion.

Does anyone have an idea how to solve this problem??

It works fine when I log into the unix system directly from Xterm in the same way as above, but I perfer to use Terminal.

Any help is greatly appreciated:)

Hi I also us a Mac at home. I use it to login to the server I have at home.
Anyway if -X is not working you can try using -Y. I don't think you need the -l in your command. This what I do:

ssh -X [username]@[servername]

If you create an account on your Mac with the same username as the account you use at school and only need this:

ssh -X [servername]

If you do this then you can even use RSA or DSA keys to login instead of using your password. More secure.

Also check your firewall and network setting Lion may have made some unwanted changes.

A little late but I hope it helps.
