Description Aleksander Alekseev 2016-09-04 12:10:06 UTC
Hardware:

- Fujitsu Lifebook E733 laptop
- Intel HD Graphics 4000

I have:

```
i915kms_load="YES"
```

... line in /boot/loader.conf

I noticed that after executing `kldunload i915kms` screen turns black. And here is how it looks after pressing any button on a keyboard:

Granted it's a minor issue since most users will never unload i915kms. Still it would be nice if driver could be properly unloaded.

Naturally if you need any additional information to debug this issue I would be happy to provide it.
