Bug#963980: bumblebee-nvidia: Bumblebee daemon reported: error: [XORG] (EE) Unable to locate/open config directory

[Vincas Dargis]

OK so it looks like after 2020-09-01 updates that had lot's of NVIDIA stuff, same error reproduces again:

```
$ pvkrun vkcube
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Unable to locate/open config directory: 
"/etc/bumblebee/xorg.conf.d"
```

```
$ optirun glxgears
[ 5856.436157] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Unable to locate/open config directory: 
"/etc/bumblebee/xorg.conf.d"

[ 5856.436198] [ERROR]Aborting because fallback start is disabled.
```


```
$ primusrun glxgears
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Unable to locate/open config directory: 
"/etc/bumblebee/xorg.conf.d
```

optirun/primusrun/pvkrun does not work. glxgears does run with integrated graphics, but not with NVIDIA.

Attached /etc/bumblebee directory contents.

Here's what /var/log/apt/history.log tells:
