When I do "ssh -X abcserver", I got message "X11 forwarding request failed on channel 0". I checked online and it was suggested to solve it by switching "X11UseLocalhost no" to "X11UseLocalhost yes".
However, both my manager and I don't have this administrative privilege. I am wondering, except this solution, whether there is another option to solve the issue ? I also don't have sudo privilege to directly install X11 on the server.
My local platform is:
Linux version 3.16.0-4-amd64 ([email protected]) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) The remote platform is:
Linux version 3.13.0-88-generic (buildd@lgw01-16) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #135-Ubuntu SMP Wed Jun 8 21:10:42 UTC 2016

The broken X11 forwarding error may also happen if the remote host where SSH server is running has IPv6 disabled. To fix the error in this case, open /etc/ssh/sshd_config file, and uncomment AddressFamily all (if any).
In PuTTY for Windows, you can enable X forwarding in new or saved SSH sessions by selecting Enable X11 forwarding in the "PuTTY Configuration" window (Connection > SSH > X11).
To test to make sure X11 is working properly, run “xeyes” and a simple GUI should appear on the screen. That's it!
X11 forwarding is a mechanism that allows a user to start up remote applications, and then forward the application display to their local Windows machine. It enables you to run GUIs from a local server. It's essentially remote desktop software that looks better on your screen and is easier to work with.
Adding the -v option to ssh when trying to log in will give a lot of debug information which might give a clue to exactly what the problem is, like for instance
debug1: Remote: No xauth program; cannot forward with spoofing. which in my case installing xauth on the server fixed the issue.
