glvis over x2go connection to remote sever results in FATAL: window and/or OpenGL context creation failed.

[justfredje]

I'm trying to use glvis over a x2go session (MATE) to a remote server (CentOS7) where I compiled glvis.

When I am at the server itself glvis works without issues either in a GNOME or MATE desktop session. Also using nomachine works when working remotely (but has other limitations when using the free version).

However when connection through x2go I get "FATAL: window and/or OpenGL context creation failed." printed on the terminal window where I started glvis.

Not being very savy in these things could someone explain me what I should do to get glvis and x2go work nicely together.
Many thanks upfront !

PS glxgears does work over x2go.

PS2 I also notice that one can visualize in a browser which could be a workaround but I did not find understand how to set this up.

Can you try the option -oldgl?

Hi,

Thanks for your reply: in the x2go session I tried

$ ./glvis -oldgl

but got the same result.

I've never used x2go, so I'm not sure how it works. It sounds like it forwards X11 connections from the remote host to the local host which should be running an X server. What is the OS on the local machine and what X server is it running?

You can also check out the following issue, they may give you come clues:

• Black screen with VNC on remote CentOS7, "Window type not found" through X11 #112
• WSL__empty_window #218
