我在通过 USB-C 将外部显示器连接到我运行 i3 作为窗口管理器的 arch Linux 机器时遇到了这个奇怪的问题。
我的设置是联想 Thinkvision T27hv-20 作为扩展坞，通过 USB-C 连接（也可以为我的机器充电）和以菊花链方式连接到 Thinkvision 的戴尔显示器。
我可以看到通过 xrandr/DP 连接的显示器，但 xrandr --auto 或 xrandr --output DisplayPort-x --auto 不会唤醒显示器。当我通过 HDMI 电缆和适配器连接时，它可以工作。
我可以排除电缆问题 - 在另一台机器（kali linux）上工作正常。
我正式没有想法了——有人遇到同样的问题吗？

答案1
我通过禁用异步翻转解决了这个问题。我创建了这个文件：/etc/X11/xorg.conf.d/20-noasyncflip.conf
然后添加了这个：
Section "Device"
Identifier "Device0"
Driver "modesetting"
Option "PageFlip" "off"
EndSection
快速重启后：
sudo systemctl restart display-manager.service
（或者只是重新启动），这解决了我的问题。
我的问题是：我可以看到光标，启动系统后几秒钟一切都很好。有时，更新分辨率时它也可以工作，但仅适用于 1 台显示器（有 2 台外接显示器）。
