这台笔记本电脑上的 Wifi 在 ubuntu 14.10 下运行良好。我安装了内核为 4.0 的每日 15.04 以激活 FocalTech 触摸板。但现在 Wifi 不再工作(它也无法与 15.04 原版内核 v3.19 配合使用)。
我正在寻找一些关于如何解决此问题的线索。

答案1
这可能有用sudo apt-get purge bcmwl-kernel-source
sudo apt-get install bcmwl-kernel-source
在 3.19 内核中
还要检查lsmod | grep acer
是否列出了 acer_wmi,然后
echo "blacklist acer_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
答案2
Focaltech 将致力于开发 3.19 版本。
sudo add-apt-repository ppa:hanipouspilot/focaltech-dkms
sudo apt-get update
sudo apt-get install focaltech-dkms
