我正在尝试使用 tightvnc 在 Ubuntu 22.04 中设置 VNC 服务器。我基本上可以正常工作，只是 gnome 会话无法正确显示。它看起来像这样：
它有点像 gnome classic，但没有桌面背景，所以显然内容没有完全加载。
这是我的 ~/.vnc/xstartup 文件：
$ cat ~/.vnc/xstartup
#!/bin/sh
autocutsel -fork
xrdb $HOME/.Xresources
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:Unity"
export XDG_MENU_PREFIX="gnome-flashback-"
unset DBUS_SESSION_BUS_ADDRESS
gnome-session --session=gnome-flashback-metacity --disable-acceleration-check --debug &
我也尝试了另一个版本，它基本上看起来相同：
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
x-window-manager &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
这是我的 systemd 服务：
$ cat /etc/systemd/system/[email protected]
[Unit]

ExecStop=/usr/bin/vncserver -kill :%i
[Install]
WantedBy=multi-user.target
我的 .Xresources 文件是空的（但是存在）。
最后，服务的当前状态出现了一些错误，但我不知道它们是什么意思或者如何调试它们：

关于如何使 gnome 会话看起来像默认的 gnome 环境，您有什么想法吗？我是否只需要安装一些其他扩展，还是我做错了？
