答案1
这是 atheros wi-fi 和 acer_wmi 模块的已知问题。
尝试加入黑名单acer_wmi
按 Ctrl + Alt + T 并粘贴以下文本：
echo blacklist acer-wmi | sudo tee /etc/modprobe.d/blacklist-acer-wmi
然后你可以重新启动或者输入sudo rmmod acer-wmi
如果此方法无效，而您想要恢复，
删除/etc/modprobe.d/blacklist-acer-wmi（通过单击您的主文件夹，单击左侧窗格中“计算机”下的“文件系统”，双击 etc，然后双击 modprobe.d 并删除文件“blacklist-acer-wmi”）
