我最近从 升级到Ubuntu 20.04 LTS
,Ubuntu 21.10
现在,正如标题所示,当通过标题中提到的 ThinkPad 底座的混合 USB-A 电缆连接时,我的外接显示器不再被检测到。
我过去曾遇到过外接显示器问题,因此我尝试做的第一件事就是重新安装 DisplayLink 驱动程序:https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu
起初,驱动程序无法在 Wayland 的默认启动中安装(未找到 EVDI 1.9.1 包或库),但我切换到 Xorg,然后驱动程序似乎安装成功(尽管出现了非致命错误)并提示重新启动:
sudo ./displaylink-driver-5.4.1-55.174.run
Verifying archive integrity... 100% All good.

Installation complete!
Please reboot your computer if intending to use Xorg.
另一件可能有用的事情是
xrandr --listmonitors
即:
Monitors: 1
0: +*eDP-1 1920/276x1080/155+0+0 eDP-1
如果我通过 HDMI 电缆将其中一台显示器直接连接到笔记本电脑,它就能正常工作。
真的不知道还能做什么。希望我不必重新安装 20.04 就能让我的外接显示器再次通过底座工作。
任何帮助深表感谢!
