This is closely related to this question: How can I tell Ubuntu to do nothing when I close my laptop lid?.
I would like to stop Ubuntu from suspending or sleeping when the laptop lid is closed, while still turning the screen off to save power. How can I do that?
This is for a Dell Precision 5550 running Ubuntu 20.04 preinstalled.
目前，每当我将蓝牙耳机重新连接到 Ubuntu 22.04 时，它都会默认使用 A2DP Sink 配置文件。然后我每次都使用 pavucontrol 手动切换到 HFP。我怎样才能让它坚持下去，这样我就不必不断改变它？
我已经尝试过更改蓝牙耳机默认音频模式（A2DP Sink 与 HSP/HFP）中的解决方案，但似乎都不起作用。
