Anyone able to help me with a xrandr prompt?

[Macfunky]

In Ubuntu i have no problems setting up my dual monitor set up using -

xrandr --output DVI-I-1 --left-of DVI-I-2

I then go into display and change the resolution of one of the monitors. Using LXDE i can't seem to change the resolution using the display settings tool. It simply won't apply the changed settings for some reason so i'm wondering, can i include the screen resolutions into the xrandr prompt? My left screen is 1280x1024 and the right one is 1440x900. Anyone able to help me to do that?

Just a guess:

xrandr --output DVI-I-1 --left-of DVI-I-2 -s 1280x1024 --output DVI-I-2 -s 1440x900
It may be worth installing arandr, which is a graphical front-end to xrandr.

That's all the info i needed. Thank you very much :) Didn't know about arandr :)
