Editing Displaying X windows applications on a Windows desktop

=Setting the X11 display to show X applications under Windows=
For win2k, win7

Start up X-Win32 / Xming and an XDMCP / broadcast session. Make sure the server you are going to run the application from has permissions in the X-server (for Xming it's in the X0.hosts file)

Before you putty into the machine make sure you go to connection -> SSH -> X11 and set Enable X11 forwarding on.

Make sure the machine with the program on it (eg. /usr/games/tuxeyes) has xdm installed, and has open ports on the firewall (eg /etc/shorewall/rules:


ACCEPT   fw     loc     tcp     x11

ACCEPT   fw     loc     udp     x11

run the program :) (eg xeyes)

Alternatively in a terminal window ssh in using the -X or -Y options, eg

ssh -X user@ipofserver or ssh -Y user@ipofserver or ssh -XC user@ipofserver

If you want to run the entire desktop you can run xfce4-session (Assuming the server has an xfce desktop installed)

=Troubleshooting=	       
== Xming.exe: client 4 rejected from IP 192.168.1.215==

Solution:

Edit: X0.hosts (c:\program files*86)\xming\ in the installation directory)

add the ip you want allow. my X0.hosts

“localhost

192.168.1.215″

Restart Xming.

==NV-GLX missing on display==

Try the following commands for this error
<pre>
glxgears
</pre>
You should see spinning gears if it works

<pre>
glxinfo
</pre>
should also give the error at the top if it doesn't work

This is usually because the propriatary driver is installed on the machine running glxinfo , and that driver expects the NV-GLX extension loaded in the X server, which is clearly not the case. Try removing the nvidia proprietary driver. [https://www.linuxquestions.org/questions/linux-general-1/nv-glx-missing-in-remote-connections-4175463926/ adamk75]
After removing the driver, logout and login.

You can try setting the following environment variable
<pre>
export LIBGL_ALWAYS_INDIRECT=y
</pre>

= Alternatives to X-Win: =

Xming

XWinLogon Win32 X Server

Cygwin/X

NB To do this in a linux desktop just
<pre>
ssh -XC user@ip
</pre>

= Depreciated and insecure (manually setting the export environment)! =

Putty into the machine you're running stuff off:

export DISPLAY=YOUR IP:0
