m.nviz.image: "failed to create pixmap"

[hamish]

Hi,

when running m.nviz.image on Linux I get an error message:

failed to create pixmap

but otherwise all seems ok and I get the output I expect, so seems harmless.

Seems to happen in Nviz_create_render_window() during

    /* create an off-screen GLX rendering area */
    rwin->windowId = glXCreateGLXPixmap(rwin->displayId, v, rwin->pixmap);

I tried with and without GRASS_NO_GLX_PBUFFERS=1 and GRASS_NO_GLX_PIXMAPS=1 being set, same thing.

Replying to hamish:

I tried with and without GRASS_NO_GLX_PBUFFERS=1 and GRASS_NO_GLX_PIXMAPS=1 being set, same thing.

Those variables are implemented in NVIZ (visualization/nviz/src/do_zoom.c), so they won't affect anything else.
