fedora 21 tigervnc resolution settings

Question

I'm using fedora 21 remotely from Win7 remote desktop client. But the tigervnc screen resolution size is not properly set automatically. So I have to enter the following command every time after the gnome3 session begins.

xrandr --output VNC-0 --mode 1280x1024

I want to run this command automatically every time when gnome session begins. How can I do this? By the way my current ".vnc/xstartup" is like following.

$ cat $HOME/.vnc/xstartup

#!/bin/sh
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
vncconfig -iconic &
dbus-launch --exit-with-session gnome-session &

Any idea?

I searched over the web and found the information about this. So, I tried the following. And it seems working.

1) Make a *.desktop file under the .config/autostart/ directory.

$ vi $HOME/.config/autostart/xrandr-startup.desktop

[Desktop Entry]
Name=xrandr-startup
GenericName=xrandr-startup
Comment=Start these up at login
Exec=/usr/local/bin/xrandr-startup.sh
Terminal=False
Type=Application
X-GNOME-Autostart-enabled=true

2) Make a shell script which runs xrandr command.

# vi /usr/local/bin/xrandr-startup.sh

#!/bin/sh
xrandr --output VNC-0 --mode 1280x1024

# chmod +x /usr/local/bin/xrandr-startup.sh

But some times, following dialog displayed before login.

I'm not sure how to avoid this.
