我在华为 Matebook HZ-W19 上使用 Ubuntu。
我的无线网卡 (BCM 4356) 无法与最新版本的 linux 固件 (1.173.3) 兼容，但可以与版本 1.156 兼容。然而，使用最后一个版本时，我的桌面 (Budgie、Gnome、Deepin、KDE) 出现故障。
所以现在我问自己是否可以从 1.156 获取无线网卡驱动程序并将其插入到 1.173 包中。

好的，无线问题的解决方案如下：https://www.reddit.com/r/thinkpad/comments/8pvd34/found_solution_for_bcm_4356_adapter_problems_in/
通过添加此内核参数解决了屏幕闪烁问题：
