Re: [opendx-users] Image: Display: Bad parameter: Cannot open X display ':0.0'
Did it really use 10.0 and not 11.0? David So what is the DISPLAY set to when you run it remotely via -script? On the remote computer: ~ echo $DISPLAY s00505:11.0 I thought that OpenDX might have a problem with resolving the s00505 name, so I fully qualified it to DISPLAY=s00505.nersc.gov:11.0 and ran: dx -execonly -verbose, but I got the same error. Because I passed the -verbose option, I was able to see the actual value OpenDX uses: DISPLAY=s00505.nersc.gov:10.0 I really have no idea what the problem might be. Thanks best, Irek -- . David L.

Re: [opendx-users] Image: Display: Bad parameter: Cannot open X display ':0.0'
It was a typo in my e-mail. I was logging in several times to make sure that the problem is reproducible and simply mixed some values in my e-mail. Excuse me this. When I was running OpenDX I was using the corret values for DISPLAY.

Re: [opendx-users] Image: Display: Bad parameter: Cannot open X display ':0.0'
No, it does work such that the OpenDX server creates an X11 window and then the GUI attaches itself to it. The server and the GUI talk to the same X window by setting up callbacks on the one X window. Can you run dx in script mode and get an x window to pop up on your local system? David Hi Marilyn, Brent others, Thanks you for your responses. Do you need to ssh -X to enable X data through from the server, or an xhosts + to let the workstation display X data from a remote server? Yes, I made sure X11 forwarding is enabled. I ran xterm to check it. So this is not the problem. I am not sure that OpenDX works that way: that the OpenDX server opens a regular X11 window. I suspect that the server communicates with the GUI, and GUI is responsible for displaying the image. I think that way, because when I ran my program the GUI opened a black window for an image. The window remained open after I killed the server. Best, Irek -- . David L.

Re: [opendx-users] Image: Display: Bad parameter: Cannot open X display ':0.0'
Irek, Make sure that ssh is configured to pass X - look in the ssh.config file and confirm that X forwarding is on. Try running ssh with the parameter -X in addition to the ones you have. Marilyn NYU
