我在連接第二台顯示器時遇到問題。我的筆記型電腦只有 HDMI 插頭，我需要使用 DVI 電纜。為此，我購買了 USB-C 轉 DVI/VGA/HDMI/USB3 轉接器。
不幸的是它不起作用。如果我將USB 記憶棒插入適配器，就會立即識別出來（所以我猜測適配器本身可以工作，並且我的Linux 系統「看到」它），但我嘗試使用HDMI、VGA 和DVI，但它們都不起作用。筆記型電腦根本無法辨識任何螢幕。
我在 Windows 電腦和 MacBook PRO 上嘗試了該適配器，兩者都運作得很好。
適配器是這個！
我的筆記型電腦是 Tuxedo InfinityBook PRO。
運行 Ubuntu 16.04（核心 4.13.0-43-generic）
任何幫助表示讚賞。
先致謝

這是連接適配器後我的系統日誌檔案：
