尝试使用 Raspberry Pi 4B 在 Ubuntu 23.04 上设置 TigerVNC。
输入“vncserver”进入测试步骤。
收到此输出：
New Xtigervnc server 'KG7JE-Ham:1 (steve)' on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /tmp/tigervnc.IZRuvV/passwd :1 to connect to the VNC server.
--- tail /home/steve/.vnc/KG7JE-Ham:1.log---
Session startup via '/home/steve/.vnc/xstartup' cleanly exited too early (< 3 seconds)!
Maybe try something simple first, e.g.,
tigervncserver -xstartup /usr/bin/xterm
The X session cleanly exited!
Killing Xtigervnc process ID 576114... success!
因此，尝试了tigervncserver -xstartup /usr/bin/xterm这个输出：
New Xtigervnc server 'KG7JE-Ham:1 (steve)' on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /tmp/tigervnc.aBtKL_/passwd :1 to connect to the VNC server.
这似乎有效，因为我看到了锁定文件/tmp/。
那么，vncserver 出了什么问题？
输出如下./.vnc/*.log：
_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root

答案1
问题出在这一行：
/usr/bin/startxfce4: X server already running on display :1
对我有用的是删除 xstartup 以下行中的“&”：
startxfce4 &
因此，我现在的思路很简单：
startxfce4
