為什麼在 Fedora 23 中未檢測到我的（thunderbolt 連接的）監視器
我有一台戴爾 XPS13，其飛利浦 UltraWide 顯示器通過 Thunderbolt 3/USB-C 連接。由於除了 Apple 顯示器之外沒有其他顯示器支持這種新奇的連接，所以我有一個外部轉換器到 HDMI（我也嘗試過 DVI 和 Mini HDMI）。但是 Fedora 23 沒有檢測到我的顯示器。/etc/X11/xorg.conf.d沒有什麼用處，只有一個鍵盤配置。在*/usr/share/X11/xorg.conf.d*也沒有什麼用處。
我嘗試過重新啟動，插入後重新啟動，未插入，以終端模式重新啟動（插入和未插入）並執行
startx有什麼想法為什麼或有什麼我可以嘗試的嗎？當然，總是有可能不支持它。Linux 還不支持這個東西上的 Wifi。
Linux 核心 4.1 & 4.2 錯誤
Linux Kernel 4.1、4.2 和 4.3 上的 Thunderbolt存在一個現有錯誤，但我已經下載了 Fedora 22 Live 並從中啟動（使用 Kernel 4.0），我也遇到了同樣的問題。

存在一個錯誤，即在 Linux 核心 4.1、4.2 和 4.3 中無法辨識 Thunderbolt 連接，但在 4.0 中。
這已在核心 4.4 中修復，因此添加更新的核心可以修復它。由於 Fedora 23 沒有更新到 4.4。直到 Fedora 24（實際上是 4.6）。如果您使用的是舊版本，可以手動完成，如下所示
添加核心香草回購
curl -s https://repos.fedorapeople.org/repos/thl/kernel-vanilla.repo | sudo tee /etc/yum.repos.d/kernel-vanilla.repo安裝穩定版本（如果你夠勇敢，也可以安裝 dev [ kernel-vanilla-mainline ]）
sudo dnf --enablerepo=kernel-vanilla-stable update然後重新啟動，核心 4.4 將成為啟動時的一個選項。
我不知道為什麼帶有核心 4.0 的 Fedora 不起作用。
