膝上型电脑无法输入iwlwifi

Question

Ubuntu18.04无法检测到我笔记本电脑的Wifi适配器，Intel AC 9560。就在我把Ubuntu安装在笔记本电脑的同一天，这种情况似乎是随机发生的。这似乎是iwlwifi没有正确初始化的结果。正如其他帖子所建议的那样，我安装了支持iwlwifi的iwlwifi，以将固件从43升级到46。升级后Iwlwifi仍然无法初始化。我还能做什么呢？

dmesg \ grep iwlwifi

编辑：

正如在这个注释中所指出的，https://askubuntu.com/a/1203223/1032323，音频在使用这里描述的解决方案https://askubuntu.com/a/1201620/1032323之后会失败。根据我的经验，我的笔记本电脑也无法在不挂起的情况下关闭或重新启动。因此，我启动了原始内核，并按照这里的说明用Ubuntu18.04.3 LTS无线/音频不工作的戴尔沃斯特罗155590。此解决方案解决了音频和关机问题，但iwlwifi驱动程序在挂起膝上型计算机后可能会失败。我可以重新加载驱动程序来解决这个问题，但我正在寻找一个更永久的解决方案。

请查看这个bug报告：https://bugs.launchpad.net/ubuntu/+source/linux-oem-osp1/+bug/1835879，它建议您的设备不受支持，但是在linux osp1 1包中得到了支持。

您的设备还需要在18.04版的linux固件包中不存在的固件。我们把这两样都修好。通过以太网、捆绑或任何可能的方式临时连接互联网，打开终端并做：

wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux*.deb

其次是：

sudo apt update
sudo apt install linux-oem-osp1

还将安装几个依赖项。

重新启动并向我们展示一个新的：

dmesg | grep iwl

Answer 3

新固件导致我的音频输出出错。

iwlwifi问题在几次启动和重新启动之后再次出现。

你能再查一次吗？
