after installation Xming on Windows PC for Putty dont run DISPLAY=:0 first. It should work without that.
1. Forward applications and not an entire desktop
ssh -X -c blowfish user@server
see man ssh.
2. Learn the command line
The majority of server management is editing text files which does not require X.
3. Use a web tool / web interface, ie webmin (or similar).
for OpenGL try this
If OpenGL doesn't work with a program then you can switch on various diagnostic output. Start Xming with special environment variables set
Variable Description
GLWIN_ENABLE_DEBUG=1 Enable debugging output at all.
GLWIN_ENABLE_TRACE=1 Enable trace output.
GLWIN_ENABLE_STEREO=1 Enable stereo visuals in GLX.
GLWIN_DUMP_PFD=1 Output information on the requested visual and pixelformat.
GLWIN_DUMP_HWND=1 Output the window handles used in some operations.
GLWIN_DUMP_DC=1 Output the device context handle used in some operations.
For example
>set GLWIN_ENABLE_DEBUG=1
>set GLWIN_DUMP_PFD=1
>Xming :0 -multiwindow -clipboard
or try the alternative Mesa renderer instead. Also a difficult client will usually work if a version of Mesa is installed on the remote Linux/Unix machine to preempt server-side rendering.
yes you can work with sever over vpn .you can manually verify the DISPLAY variable is correct is:
1. Start your VPN. Run ipconfig to be sure you have the two IP addresses you mentioned (your local IP and your VPN IP).
2. Start Xming. Run 'netstat -n' to see how it's binding to the interface. You should see something that either says localIP:6000 or VPNIP:6000. It may not be 6000 but chances are it will be something like that. If there's no VPNIP:6000 it may be binding only to your localIP or even 127.0.0.1. That will probably not work over the VPN. Check if there are some Xming settings to make it bind to other or all interfaces.
3. If you see VPNIP:6000 or something similar, take note of what it says and remote shell into your UNIX host (hopefully something like ssh, if not whatever you have to get a text terminal).
4. On the UNIX terminal type 'echo $DISPLAY'. If there is nothing displayed try 'export DISPLAY=VPNIP:0.0' where VPNIP is your VPN IP address and 0.0 is the port you saw in step 3 minus 6000 with .0 at the end (i.e. 6000 = 0.0, 6010 = 10.0).
5. On the UNIX host run something like 'xclock' or 'xterm' to see if it runs. The error message should be informative. It will tell you that it either couldn't connect to the host (a connectivity problem) or authentication failed (you'll need to coordinate Xauth on your host and local machine or Xhosts on your local machine).
