Ubuntu 25.10 seems to support this configuration better.
AMD is used by default for the OpenGL renderer:
glxinfo|grep -i renderer
GLX_MESA_copy_sub_buffer, GLX_MESA_gl_interop, GLX_MESA_query_renderer,
GLX_MESA_gl_interop, GLX_MESA_query_renderer, GLX_MESA_swap_control,
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: AMD Radeon 890M Graphics (radeonsi, gfx1150, LLVM
20.1.8, DRM 3.64, 6.17.0-5-generic)
but the nVidia card is available as well
