ubuntu 18.04.3 LTS 无法识别我的 MacBook 板载摄像头

我最近用 Ubuntu 18.04.3 替换了我的 macair 操作系统。我安装了 skype，发现摄像头无法识别。

以下是有关我的系统的一些信息：

lshw输出

description: Laptop
product: MacBookAir7,1 (System SKU#)
vendor: Apple Inc.
version: 1.0
serial: C02P7CM7GFWM
width: 64 bits
capabilities: smbios-2.7 dmi-2.7 smp vsyscall32
configuration: boot=normal chassis=laptop family=Mac sku=System SKU# uuid=6CC9DA71-AC5E-7B52-AB2A-5CC6442374ED

的结果

sudo lsmod | grep video

给出

video  49152  1 i915

/etc/local/src在我的配置中不存在

下/usr/src，我有以下内容

bcmwl-6.30.223.271+bdcom  linux-headers-5.0.0-23  linux-headers-5.0.0-23-generic

如果有人愿意帮助我解决这个问题，我很乐意听到他们的意见。

来自@simon-shields 编辑的问题：

这就是我修复它的方法。

（请注意，这需要curl安装，可以使用 来完成sudo apt install curl。）

1）克隆来自https://github.com/patjak/bcwc_pcie.git

$ cd /usr/local/src
$ sudo git clone https://github.com/patjak/bcwc_pcie.git
Cloning into 'bcwc_pcie'...
remote: Enumerating objects: 8, done.
remote: Counting objects: 100% (8/8), done.

Resolving deltas: 100% (709/709), done.

2）从以下位置克隆 facetimehd 固件https://github.com/patjak/facetimehd-firmware进入 bcwc_pcie 文件夹

$ cd /usr/local/src/bcwc_pcie
$ sudo git clone https://github.com/patjak/facetimehd-firmware
Cloning into 'facetimehd-firmware'...
remote: Enumerating objects: 1, done.
remote: Counting objects: 100% (1/1), done.

Resolving deltas: 100% (585/585), done.

3）构建并安装 facetimehd-firmware

$ cd /usr/local/src/bcwc_pcie/facetimehd-firmware
$ sudo make

Checking dependencies for driver download...
/usr/bin/curl
/usr/bin/xzcat
/bin/cpio

Downloading the driver, please wait...

$ sudo make install
Copying firmware into '//lib/firmware/facetimehd'

4）制作并安装bcwc_pcie驱动

$ cd /usr/local/src/bcwc_pcie
$ sudo make
make -C /lib/modules/5.0.0-23-generic/build M=/usr/local/src/bcwc_pcie modules
make[1]: Entering directory '/usr/src/linux-headers-5.0.0-23-generic'

$ sudo make install

5）启用驱动程序

$ sudo depmod
$ sudo modprobe -r bdc_pci
$ sudo modprobe facetimehd

现在 Skype 使用 facetimehd 驱动程序进行视频传输。

但是，由于某种原因，相机直到被另一个本机应用程序（例如奶酪）使用时才打开。

$ sudo apt install cheese

**6) 确保facetime高清重新启动后开始添加一行
/etc/模块通过运行命令
sudo echo facetimehd >> /etc/modules
