我以某种方式在 Ubuntu 18.04 中激活了“电池满电”警报音，现在我想禁用它，因为我的电池出现故障，它经常响并且声音很大。
我怎样才能消除该音调，或者怎样才能禁用监控电池状态并发送电池已满警报的服务？
答案1
在 Ubuntu 18.04 中默认
gsettings对于模式org.gnome.desktop.sound和关键event-sounds是true
pratap@i7:~$ gsettings get org.gnome.desktop.sound event-sounds
true
pratap@i7:~$
将键值设为 false 将停止所有事件声音。
仅停止电池充满事件声音..
检查声音主题名称
pratap@i7:~$ gsettings get org.gnome.desktop.sound theme-name
'ubuntu'
pratap@i7:~$
列出并查找它是否有battery-full声音文件..

battery-full.oga使用以下命令重命名文件..
sudo mv /usr/share/sounds/Smooth/stereo/battery-full.oga /usr/share/sounds/Smooth/stereo/battery-full.oga.bak
就是这样.. 发出事件声音.. 它无法找到，battery-full.oga因为它已被重命名为battery-full.oga.bak
