vtkXOpenGLRenderWindow: Could Not Find a Decent Config or Visual on embedded Linux system with EGL only

Development

Hello everyone,

I’m new to VTK and I’m encountering an issue when trying to render CylinderExample

vtkXOpenGLRenderWindow.:266 ERR| vtkXOpenGLRenderWindow (0x34ea11c0): Could not find a decent config
vtkXOpenGLRenderWindow.:484 ERR| vtkXOpenGLRenderWindow (0x34ea11c0): Could not find a decent visual

This error seems similar to this issue, but in my case, it’s not occurring at WSL

The difference situation is：

This looks like insufficient OpenGL support in the X driver stack to me. Does glxgears work?

Not supported by VTK (yet).

EGL onscreen windows are not supported in VTK. if you are interested in contributing support for this feature, VTK using on wayland - #13 by jaswantp has some notes that will guide you.
