VNC桌面灰色问题请教

一次重启服务器后，启动VNC服务，提示一下信息，但是VNC远程接入还是可以使用，界面是灰色的
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "zh_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
xauth: timeout in locking authority file /home/oracle/.Xauthority

New 'oracle:1 (oracle)' desktop is oracle:1

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/oracle:1.log


xstartup是已经修改过的
#!/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 $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
gnome-session &

已经在网上搜索了很多资料都不能有效的解决，请大家多多帮助解决一下这个问题
