在配置Centos 7下VNC時發現root用戶可以正常登陸VNC桌面，而普通用戶VNC桌面黑屏，分析~/.vnc/xstarup 后發現是普通用戶沒有執行/etc/X11/xinit/xinitrc的權限

#!/bin/shunset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS /etc/X11/xinit/xinitrc # Assume either Gnome or KDE will be started by default when installed # We want to kill the session automatically in this case when user logs out. In case you modify # /etc/X11/xinit/Xclients or ~/.Xclients yourself to achieve a different result, then you should # be responsible to modify below code to avoid that your session will be automatically killed if [ -e /usr/bin/gnome-session -o -e /usr/bin/startkde ]; thenvncserver -kill $DISPLAY fi

root權限依次執行以下命令，給其他用戶對此文件的讀和執行權限

#chmod 755 /etc/X11/xinit/xinitrc #chmod 755 /etc/X11/xinit/xinitrc-common

這時用普通用戶權限執行 /etc/X11/xinit/xinitrc，出現以下錯誤

yala@A-boat:~$ /etc/X11/xinit/xinitrc xrdb: Can't open display '' xmodmap: unable to open display ''(process:1367): dconf-CRITICAL **: 10:39:23.653: unable to create file '/run/user/1001/dconf/user': 權限不夠. dconf will not work properly.(process:1367): dconf-CRITICAL **: 10:39:23.654: unable to create file '/run/user/1001/dconf/user': 權限不夠. dconf will not work properly.

我們把對應文件chown下

chown yala:yala /run/user/1001/dconf -R
