TightVNC中带有十字光标的灰色屏幕

Question

我正在尝试从Windows 10 VNC到Ununtu 16.04。我得到一个带有十字光标的纹理灰色屏幕。

以下是我的日志文件：

我的xtartup文件如下：

#!/bin/sh

# 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 &

我已经彻底搜索了互联网，并尝试了很多建议，但我找不到任何东西。如果我评论xstartup文件中的最后两行，我会得到一个更平滑的灰色版本，左上角有3个复选框。我正在寻找的是一个GUI，就像我直接使用该机器一样。

编辑： 我检查过;已安装/etc/X11/xinit/xinitrc。以下是系统上的x11 *软件包列表：

编辑2： 我检查了 - 文件/etc/X11/xserver/SecurityPolicy不存在。我在线搜索。似乎很多其他人都有这个问题，但没有解决方案。
