我有一台全新的笔记本电脑。稳定的 Debian 不会启动 GNOME，也不会找到网络设备的驱动程序。最新的不稳定版本做到了。现在，没有以太网插座，没有显示 Wifi，并且在网络菜单中我没有设置它的选项。我不知道如何打开网络设备或启用 Wifi。
我已经能够通过终端收集以下信息。
我正在看什么情况？接下来的步骤应该是什么？
注意：该网络设备似乎是最新的，并且其系列在Linux中的支持很差。 install ( rtw88_8822ce) 中归属的内核模块是否适合该设备？ （或者我在哪里可以找到这些信息？）

Kernel modules: rtw88_8822ce
答案1
Realtek RTL8822CE 似乎受支持内核5.2:
5.2 的无线驱动程序下一个补丁
很可能是 5.2 新功能的最后一个补丁集，这次我们有相当多的新功能。最明显的是 Realtek 的 rtw88，它支持 RTL8822BE 和RTL8822CE802.11ac 设备。
选项CONFIG_RTW88_8822CE选项及其模块rtw88_8822ce.ko 存在在当前的 Debian bullseye/unstable 中。
阅读这个随机发现的线程：Realteck RTL8822CE 驱动程序:
发现由于错误，根据 https://ubuntuforums.org/showthread.php?t=2448425，rtw88 文件夹中没有 rtw8822c_wow_fw.bin 意味着我需要将固件更新到 1.187.2...
并再次使用检查Debian bullseye上固件文件的可用性（这将是当前不稳定的结果）搜索包内容在https://packages.debian.org/:
File Packages
/lib/firmware/rtw88/rtw8822c_wow_fw.binfirmware-realtek
让我认为你必须：
如果尚未完成，请启用 contrib 和非自由存储库。您可以更换靶心和不稳定如果那是你所拥有的，但最好不要。将其放入
/etc/apt/sources.list或中的某个位置/etc/apt/sources.list.d/：deb http://deb.debian.org/debian bullseye main contrib non-free并安装固件-realtek:
# apt-get update # apt-get install firmware-realtek
但实际上，如果没有可用的网络连接，就会出现先有鸡还是先有蛋的问题。您仍然可以从其他地方下载此软件包，使用 USB 密钥复制它并使用dpkg -i firmware-realtek_20200918-1_all.deb.这是（今天的）相关信息：
$ apt-get --print-uris download firmware-realtek/bullseye
'http://deb.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-realtek_20200918-1_all.deb' firmware-realtek_20200918-1_all.deb 716200 SHA256:24d487082fd805f9c37236df0d17a7ec157849837490113c8fc9407229acb58f
因此，即使通过“不安全”通道下载，您也可以检查校验和是否匹配。
