我正在使用Ubuntu 14.04 x64（联想G510，英特尔i5），但奶酪无法正常工作，也无法使用Skype。

我做的第一件事是

sudo apt-get install build-essential linux-headers-`uname -r`

然后，我尝试安装奶酪，sudo apt-get install cheese但我认为它已经存在，因为这是输出。

eric@eric:~$ sudo modprobe uvcvideo 什么也没给〜

一样 sudo rmmod uvcvideo

eric@eric:~$ dmesg | grep uvcvideo
[91469.832413] usbcore: registered new interface driver uvcvideo

当我做奶酪时，我得到了这个：

eric@eric:~$ cheese

我认为您应该安装UVC驱动程序。您可以从此链接获取有关解决网络摄像头问题的信息。点击这里

我也遇到这个问题...仔细检查您的键盘，看是否有带摄像头图标的多功能键...对于我的键盘，F6键多功能图标看起来像摄像头...所以我按住Fn键（通常是紫色）和F6键来打开/关闭使用网络摄像头的功能

默认情况下，ubuntu 14.04及更高版本附带必需的驱动程序
