The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interface – this is handled by individual programs.
Installing/Configuring PuTTy and Xming Most of us connect to the CTM server via a PC running Windows, essentially making the PC a terminal. The PC interacts with the server through the X-windows system, forwarding the display from the server to the PC. The X Window System (commonly X or X11) is a computer software system and network protocol that provides a graphical user interface (GUI) for networked computers. It creates a hardware abstraction layer where software is written to use a generalized set of commands, allowing for device independence and reuse of programs on any computer that implements X.

Cmder is a well-known portable terminal emulator for Windows 10 that was built from the “pure frustration” caused by the lack of a good alternative in Windows. It’s built on top of another well-known console emulator, ConEmu, and enhanced with Clink. Clink extends the power of ConEmu, adding shell features like bash-style completion. What you can do is to execute the X11 server in your Windows machine, and from a terminal (for example using PuTTY with a SSH session including X11 Forwarding), to execute some graphical programs in other machine that, by nature, works on X11 protocol. These programs will appear on your Windows screen instead of the other one.

I need to connect to a headless X Windows server (running on Ubuntu) from my MS Windows 7 computer over a 100 Mbit network. I could use VNC (or any other remote viewer) but the 3D graphics performance would be lousy I imagine. I used to have it hooked up to a monitor, but that's broken now and I can't afford a new one. A friend advised that I could try and use an X client, and that the 3D graphics wont suffer too much over 100 Mbit. Cygwin seems to be an option, but I was wondering if there were any more lightweight options.

Xming is popular and free, although since I use the rest of Cygwin anyway, I tend to use Cygwin's X server.
Oh and by the way, the client/server terminology in X seems backwards until you think about it the right way: servers are the things that provide a display service; they display the graphics and take mouse/keyboard input (like your Windows box); clients are the programs (running on Ubuntu in your case) that need the display service.
I tried transmitting 3D graphics over the network one time and figured out one thing: performance is bad. This happens because all accelerated graphics drivers do not really transmit any 3D data through the network (even if this is loopback or even UNIX abstract socket) but do some direct rendering.
The configurations I tested included both Xming (Xming is really ported Xorg) on Windows + X clients on Linux and both Xorg and clients on Linux. Network was 100Mbit, graphics card was NVidia GeForce FX 5200 (that's not a very recent card, but it definitely can handle glxgears), and both computers have PIV class processors and around 1Gb of RAM through for these two limits were not reached.
I started glxgears as a client. In both cases it displayed very chopped animation and FPS values around 30 or 50. To compare, I also run glxgears native and it showed around 8000 on Linux host and IIRC 500 on Xming with ported glxgears (that was about a year ago and Xming performance may be better now). So network performance is definitely the bottleneck for 3D graphics.

Also I must note that VNC operates only with 2D graphics: it has a very simple protocol that consists mostly of commands like 'show this rectangular image on that coordinates', so it definitely won't show any 3D performance.
It sounds like VirtualGL is the kind of thing you're looking for, though I know even less about it than the Wikipedia article. Good luck!

You might want to try Xming. Also, check out this LinuxJournal article, which gives a lot of info on the subject.
Note that on Linux, for security reasons, xdmcp is not enabled by default.For added security, I recommend you encrypt your connection using SSH. See this section from TLDP for more information about how to set everything up.

I need to get remote X11 terminal access from Windows machines into my Ubuntu 16.04 system. I am choosing not to use RDP for this since this only affects the two Windows clients.
From the other Linux boxes it is simple, especially since they use RSA authentication:
and wham, bam, I just get the prompt
But from Windows I use PuTTY which gives a great CLI connection. Quick and easy, and it saves creds so the connections are made very quickly.
When I type this on the Ubuntu command line
Which means that GUI applications will not run.
I see PuTTY has the X11 option.
But it throws an error instead of working.It needs an X server on the client side to work with Putty.
Question is in the title: How to use PuTTY to get X11 connections over ssh from Windows to Ubuntu?
Michigan Tech has a very succinct explanation of how to use Xming here:
Excerpt:
The PC interacts with the server through the X-windows system, forwarding the display from the server to the PC. Software must be installed on the PC to make this link work and the best software (so far) for this task is the PuTTy terminal emulator and the Xming X-window client.
PuTTy can be downloaded from https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
Xming can be downloaded from http://sourceforge.net/project/downloading.php?group_id=156984&filename=Xming-6-9-0-31-setup.exe
Once Xming is installed, run the application called 'XLaunch' and verify that the settings are:
Then in your PuTTY session you can turn on the X11: Enable X11 Forwarding
So then save that, and every time that session is invoked you will get a GUI connection to Ubuntu, as long as Xming is running.
Xming is verified by the visible icon in the lower right of the screen like so:
In the Xlaunch settings it is selected to not run on startup, so when you don't see that icon then click on Start, type xming and press enter and it will start the x-server and show the icon.
Now, when you make the connection, then you can see
The leafpad editor, gnome-system-monitor, etc., work over the link via the Xming server on Windows.
It is easy to pull up nautilus and browse to
to get any of the installed system commands, as shown here:
