我是 Ubuntu 的一名非常基础的用户，因此如果能得到一些帮助，我将不胜感激。我最近刚刚从 Win 10 切换到 Ubuntu 20.04，并选择了“愚蠢的人”版本，其中已经预装了许多驱动程序。我的麦克风和键盘等都可以正常工作，但我的网络摄像头却不行。打开“Cheese”时，我只收到一条消息“未找到设备”，我在网上找到了一些建议，告诉我尝试一下：
padit1337@xps:~$ ls /dev/video*
看看它是否检测到摄像头，但我收到了这个反馈
ls: cannot access '/dev/video*': No such file or directory
而且我还检查了网络摄像头是否在 UEFI 中激活，所以这不是问题。
我对 Ubuntu 的工作原理了解有限，因此在谷歌搜索了一个小时之后，我认为如果没有人工帮助，我不会找到任何有用的东西。
编辑：我插入了评论中要求的一些信息。

插入这最后一条命令后什么也没有发生。

padit1337@xps:~$ dmesg | grep "video"
这最后一条命令之后什么也没有发生。

如果您在网上搜索，会发现一些帖子表明存在一个持续存在的错误。显然，许多 Ubuntu 20.04 内核无法识别内置网络摄像头。该错误已修复，但在后续内核中又出现了。我也不是高级用户，我有和你一样的机器，但我还没弄清楚如何让它工作。
