Bumblebee after upgrade to 14 stops work

:~$ optirun glxgears
[41923.519642] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please

[41923.519725] [ERROR]Aborting because fallback start is disabled.

Why is that? Everything seems like it should be.

Try to completely remove bumblebee and reinstall it.

Have no effect.

As I don’t have the hardware to test this for myself.
