购买的全新 ASUS ZenScreen MB16AH 用于替换旧的 USB 屏幕,但无法通过 USB-C 连接。
截至撰写本文时,所有软件均处于最新状态:
- 操作系统:Ubuntu 22.04
- 核心:5.15.0-40-通用
- EVDI 内核:1.11.0 版
- DisplayLink:5.6.0-59.176
屏幕通过 HDMI 工作,但显示没信号如果通过 USB-C 连接。我的笔记本电脑的规格表明所有 USB 端口都是 USB 3.1。旧版本的 ASUS MB169B+ 工作正常。
journalctl -b
连接监视器后运行返回此日志:

并且永远地尝试。
显示器肯定已打开,因为它显示没信号消息并进入睡眠状态(琥珀色灯)。
