两个显示器有时会从挂起状态唤醒，有时则不会例如。具体来说，输入挂起并敲击键盘似乎第一次唤醒了显示器。但第二次单击“暂停”时，显示器仍然黑屏。因此，通过 USB 设备将显示器连接到笔记本电脑显示链接找不到，并且 Displaylink 驱动程序已停用。只有重启才有效。其他 USB 连接到扩展坞的设备也可以工作，例如键盘和鼠标。这个问题似乎独立于盖子位置并且不会发生‘间歇性地’。
如何排除故障？该问题是由于 DisplayLink、暂停还是其他原因造成的？
以下做了不是工作：
- 关闭 USB 自动挂起和黑名单在
tlp或 TLP UI 中。 thunderbolt-tools，tbtadm approve-all并用 进行检查lspci devices。- 拔掉扩展坞的 HDMI 或 USB-C 插头。
我不知道我会做什么：
一些可能涉及的文件
/etc/tlp.conf

/usr/lib/systemd/system-sleep/displaylink.sh
/usr/lib/systemd/system/displaylink-driver.service

日志: 挂起导致 evdi 断开/关闭？
