在我的 arm64 電腦（Ubuntu 20.04）上，直到今天早上我都在使用ightvnc。
我發現當我調整視窗大小時，它經常會卡住並斷開連接。
我以前見過這個，所以我記得我可以使用tigervnc（過去我切換到vnc4server，但我的另一台Ubuntu 20.04機器正在使用tigervnc，所以我決定更改為它）。
我刪除了tightvnc並安裝了tigervnc。
.vnc/xstartup 是這樣的：
#!/bin/bash
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec startxfce4
vncserver -localhost no :1 -geometry 3840x2160來自伺服器端的日誌connection closed unexpectedly在客戶端是這樣的（.vnc/n1sdp:1.log）

我不知道這裡的主要問題是什麼。
我不確定這是否相關，但我在這台 arm64 機器中使用了另一台機器上的 ssd 開啟金鑰來存取 git 儲存庫。
有人能告訴我這裡出了什麼問題嗎？ （我發現https://www.hiroom2.com/2018/05/07/ubuntu-1804-xrdp-xfce-en/但我不確定這是否能解決這個問題。我嘗試直到步驟 3 的 echo "xfce4-session" > ~/.xsession 並停止，因為我想使用 xfce4)
