External monitor resolution problem

edit

Hii...

I'm using fedora 19 (3.9.4-301.fc19.x86_64). I've a Dell 2010H VGA monitor. Every time, when I plug in the monitor, by default, it accepts only 1024x768 resolution. I have to manually run xrandr commands to get the proper resolution(1600x900) for the display. I'm fed up with executing xrandr newmode, & addmode each and every time. Is there any solution? Help me guys...

PS: I don't have a dedicated GPU. I've [Intel® Sandybridge Mobile]
