  In the *X display location*, enter ``localhost:0``:

- Create a launch configuration by running *XLaunch* (part of the Xming
  installation).

  - Select *Start no client*.
  - Make sure you tick *No Access Control*.
  - Click *Save configuration* and make a note of where you save the
    ``.xlaunch`` file.

- Start *Xming* by double clicking on the ``.xlaunch`` file.
- Log into your Linux box using ``putty``.  At the Linux terminal, you
  might need to type:

  ::

    DISPLAY=your.windows.ip.address:0.0;export DISPLAY

  Note: When I tried this, the fonts look messy.  More information on fonts
  can be found here: `Xming Fonts`_

Logging
-------

If you have any issues with the connection, check the *Xming* log.  This can
be found by right clicking on the *Xming* icon in the toolbar...

Multi-Monitor (Rotate)
----------------------

From the comments on `Ubuntu: Rotate only one of two monitors`_...

... *After messing around a bit with xorg.conf, the solution for me was
surprisingly simple: Completely remove all NVIDIA drivers and the xorg.conf. In
the display settings I can now rotate and position both displays individually
in a few seconds without having to change xorg.conf and without restarting X*.

*The downside is that Compiz doesn't work*...

Version
