Hi,

I have successfully forwarded OpenGL applications like PyMOL
using VirtualGL http://www.virtualgl.org/.

  3d graphics is an additional layer to the protocol and not every
server supports it, since the performance over the network is quite
poor in the best of circumstances.

Thank you Dale, but when I added " localhost:10.0"  to X display
location, the problem still exist, just without the phrase
"localhost:10.0" in the warning. My X11 forwarding is enabled all
the time and all other GUIs work just fine.

And thank you for your clarification on the concept of server and
client "in the X11 word". It makes a lot of sense and I just didn't
give it a second thought!

Best, Chen

Both the ssh client and server must be set up with "X11Forwarding
yes".  The message sounds like your local computer is not set up
to accept X11 tunneling.  (By the way, in the X11 world the remote
system is the "client" and your local system the "server".)

Hi all,

Sorry to bother you, but I am trying to fix a long-standing
problem that I cannot run Coot and Pymol through Xming/PUTTY by
SSH connection on a windows client. The error messages are
pretty similar for both: Coot: PuTTY X11 proxy: unable to connect
to forwarded X server: Network error: Connection refused
(coot-real:23113): Gtk-WARNING **: cannot open display:
localhost:10.0 Pymol: PuTTY X11 proxy: unable to connect to
forwarded X server: Network error: Connection refused freeglut
(pymol): failed to open display 'localhost:10.0'

Does anybody have some ideas?

Thank you so much, Chen
