自 Ubuntu 22.04 升级以来，VNC 服务器无法正常工作

我的服务器上运行着一些 TigerVNC 实例，用于远程访问。我将它们作为 systemd 服务启动。

自从升级到 Ubuntu 20.04 到 22.04 后，服务器无法启动并出现错误：

Session startup via '/home/VNC/.vnc/xstartup' cleanly exited too early (< 3 seconds)!

有人能给我指出正确的方向吗？

以下是我对服务的定义：

[Unit]
 Description=Remote desktop service (VNC)
 After=syslog.target network.target

[Service]
  Type=forking
  User=VNC
  PIDFile=/home/VNC/.vnc/%H:%i.pid
  ExecStartPre=-/usr/bin/vncserver -kill :%i
  ExecStart=/usr/bin/vncserver -localhost no -depth 24 -geometry 1920x1080 :%i
  ExecStop=/usr/bin/vncserver -kill :%i

[Install]
  WantedBy=multi-user.target

以下是我对 &HOME/.vnc/xstartup 的开始：

#!/bin/bash
xhost +
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
autocutsel -fork
startxfce4 &

我读了论坛上的一篇文章，其中谈到新的 vncserver 需要在前台运行，因此请从 startxfce4 命令中删除“&”。我这样做了，服务启动了。我可以从远程计算机访问，然而，大约 1 分钟后，服务停止并出现错误：Job for[电子邮件保护]由于超出超时而失败。

以下是 systemctl 状态：
