我正在尝试通过隧道使用 VNC 实现远程桌面。有人可以提供建议吗？
目前，当我通过 vnc 远程访问我的计算机时，我只看到灰色屏幕。我可以从命令行打开计算机上的窗口，但不能用鼠标管理它们（例如最小化、移动它们等）。这就像我运行了 X，但没有窗口管理器。
我使用以下命令启动 vncserver：
vncserver :1 -geometry 1920x1080 -depth 24 -dpi 96
（我已尝试过其他变体，例如单独使用 vncserver：1，或 -depth 32）。
我正在运行 18.04.2 LTS (Bionic Beaver)，我使用 xfce 作为窗口管理器
我尝试了各种各样的 xstartup 文件。这是它现在的样子，但你可以看到我一直在寻找正确的设置……到目前为止还没有找到。
#!/bin/bash
#xrdb $HOME/.Xresources
# Add the following line to ensure you alwayus haver an xterm available
#( while true ; do xterm ; done ) &
#exec /usr/bin/gnome-session
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
#exec /etc/X11/xinit/xinitrc
#[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
#[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
# xsetroot -solid grey
#vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
exec startxfce4
#twm &
#if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
# eval `dbus-launch --sh-syntax –exit-with-session`
# echo "D-BUS per-session daemon address is: \
# $DBUS_SESSION_BUS_ADDRESS"
#fi
#exec gnome-session
这是我的（已删除的）日志文件：
