bumblebee fails to disable discrete graphics card after upgrade nvidia driver to 430.40-2

I upgrade my debian just now. The nvidia-driver and other nvidia packages were upgraded to 430.40-2. Then I found that bumblebee fails to disable discrete graphics card. We can not run opengl software with command "optirun", and when I run command "lspci -nn | grep VGA", I got:

00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:3e94]
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] [10de:1cba] (rev al)

It seem that the nvidia video card can not be disabled.

My laptop is Thinkpad P1. How do I resolve this error?

Thank you very much!

Best regards,
