Hello there,

I am using x2go since many years and I appreciate it, but since a few
months my application didn=E2=80=99t work, in the past all was right and wo=
rked
fine.

I have a Mac running Hight Sierra MacOSX OS and my application uses OpenGL.
The problem comes from a call to the function =E2=80=98glXChooseVisual()=E2=
=80=99 which
don=E2=80=99t found any visual.
To prouve this issue I have used a well-known example =E2=80=98glxsimple.c=
=E2=80=99 which
said the same thing.
In this example XOpenDisplay() works, glXQueryExtension() works, but
glXChooseVisual returns NULL.

Please did you heard of this issue or help me or tell what is wrong ?

Sincerely

Philippe Dax
