How to run sketch across VNC?

Hello,

I am accessing sketch from a Windows laptop via VNC to a CentOS server (no graphics card on server).

I cannot run Sketch examples from Emacs/slime, so I am trying to debug the issue by first running the examples in sbcl running from a Gnome terminal.

I was able to run CL-SDL2 example in that sbcl.

Back to Sketch. After setting the SDL_VIDEO_X11-VISUALID to 0x210, I get a black window with error SDL error: could not generate GLX context.

Two questions:

  • Does anyone know how to deal with the GLX context error (I could not follow the discussions and solutions that I found on the web)
  • Does anyone have sketch running across VNC and can share their setup?

I realize that these issues are Lisp and Sketch unrelated, but I am hoping someone has them figured out. I also understand that this topic is quite complex, and this forum may not be the right place to look for answers.

Thanks,

Mirko

You need a graphics card to process the glx calls to get that to work.

Well, my servers don't have graphics cards, so you are onto something :-)

I'll dig a bit more into SDL on non-Graphics Card machines.
