Everything seemed to work fine *before* updating to Bumblebee 3.0. I enabled cardon/cardoff, which also worked.

Now, Bumblebee is unable to start the Nvidia card.

optirun --debug messages:
```
[ERROR]Cannot access secondary GPU - error: [XORG] (EE) [drm] failed to open device

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

grep bumblebeed /var/log/syslog error messages:
```

I tried updating Grub:
`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force nouveau.modeset=0"
`
No joy.

What other information do you need? What else should I try?
