The XQuartz package is the Mac X11 and your version is the current one. I'm wondering if you need to reboot after installation although I don't claim to know that. (And it might not hurt to repair permissions.) On my Mac (running 3.3.0 on El Cap) I need to set width and height (in inches, not pixels or points). XQuartz does not replace the system X11 on Snow Leopard, so you can go back to the Apple-provided X11.app rather easily. Just launch X11.app rather than XQuartz.app to get the older server.

X11 is a remote-display protocol used by Linux/Unix machines, including the Linux machines at Thayer. By running an X11 program (known as a server) on your computer, you can access graphical Linux programs remotely through an SSH client. In addition some *nix applications ported to macOS do not run natively under the macOS GUI and require X11.

Terminology Note: The program displaying graphics on your local machine is called an X Server, and the process on the remote end is called an X client. Yes, this may be backwards from what you might first expect. You can think of this program providing local graphics services for client programs running remotely.

Another method for accessing graphical programs remotely from our Linux compute servers is FastX. This program allows you to run a full remote desktop which can be disconnected and reconnected while graphical applications continue to run. FastX can also be much faster that X11 forwarding, especially over slower connections. For more information about downloading and setting up FastX, see this page: FastX
