我在 Fedora 工作站上配置了 Tigervnc-server，當我透過 macOS 中的 VNC 檢視器或另一個 Fedora 工作站中的 vncviewer 連接到它時，我得到的只是一個空白螢幕，有時滑鼠指標不移動。
我查看了很多論壇，這似乎是一個常見問題，但所有資訊都相當陳舊，並且與使用 systemd 和 gdm 配置 TigerVNC-server 的最新方式不同。
在這個特定的實例中，我選擇使用使用者的服務管理員（RHEL8進程）安裝tigervnc-serverhttps://access.redhat.com/solutions/4201371)) - 所以它在用戶空間中運行。
~/.vnc/xstartup 包含：
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec /etc/X11/xinit/xinitrc
~/.vnc/.log cat log2.log

日誌檔案擷取重新啟動後直接連線的兩次嘗試。即使在提示輸入密碼之前，第一個總是會失敗並顯示“哎呀”訊息。第二個顯示空白畫面。
套接字：無法取得套接字的對等名稱
這條訊息讓我認為這是一個防火牆問題，所以我也嘗試在禁用和停止防火牆的情況下進行此操作 - 但沒有運氣。
我確信這與 gdm 有關 - 但這是我薄弱的領域，因此尋求建議。謝謝
