我正在使用 Ubuntu 16.04.3 xenial。我正在尝试设置 VNC 远程会话以从我的笔记本电脑登录。VNC 服务器工作正常，我可以连接，但我看到的只是一个灰色屏幕。我使用 SSH 端口转发登录，然后启动 vncserver：
vncserver :7
我的 xstartup 文件是：
#!/bin/sh
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
xsetroot -solid "#DAB082"
x-terminal-emulator -geometry "80x24+10+10" -ls -title "$VNCDESKTOP Desktop" &
x-window-manager
就像我说的，我可以登录，但我看到的只是灰色屏幕。日志文件

我没有看到任何错误。如果我通过此 xstartup 使用 xfce4，它可以正常工作：
#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &
#unity &
“unity &” 是我为了使用 unity 而不是 xfce4 而做出的努力。我不在乎使用 xfce4，只是由于 xkeyboard 问题，我在使用 notepadqq 时遇到了问题（请参阅这里)。请注意，xfce4 日志存在问题（例如，Xlib：显示缺少扩展 RANDR”，但它仍然有效。
我查看过许多事件。我尝试过 vnc4server。当我使用 systemd 版本时，Unity 确实可以工作，但我想通过 SSH 更安全地进行端口转发来“改进”情况。
