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”)
