Hi,
I am unable to get the most recent standalone version of fsleyes to work under an up-to-date CentOS7 with a remote X2Go connection.
It shows the typical error:
stoffers at login-01 in ~
$ fsleyes
WARNING __init__.py 620: create - GLContext callback function raised RuntimeError: OpenGL 1.4 or newer is required (detected version: 1.2)
Traceback (most recent call last):

RuntimeError: OpenGL 1.4 or newer is required (detected version: 1.2)
It does run on a machine with a proper nvidia GPU when connecting through VirtualGL (vglconnect/vglrun).
Both
unset LIBGL_ALWAYS_INDIRECT
export LIBGL_ALWAYS_SOFTWARE=1
have no effect.

Is there any workaround for this? Does fsleyes only function with a proper nvidia GPU?
Best,
