[Solved]Need help with dual monitor setup

Hi,
I want to connect two monitors on laptop, one with hdmi and second with vga cable. When system boot on monitor with hdmi resolution is correct 1366x768, but on vga max resolution is 1024x768.
After running the commands below everything works fine.

xrandr --newmode "1368x768_60.00"   85.25  1366 1440 1576 1784  768 771 781 798 -hsync +vsync
xrandr --addmode VGA1 1368x768_60.00
xrandr --output VGA1 --mode 1368x768_60.00

Screen 0: minimum 8 x 8, current 2732 x 768, maximum 32767 x 32767

I use dwm with lightdm display manager. Is it possible to automate this process on startup?
Sorry for bad english

Thanks.
