I am having an (minor) issue with setting my resolution in Kubuntu 14.04 under the xrandr command line.

This is my desktop as it normally appears in the 1360x768 format. I have no issue with this.

This is my desktop as it normally appears in the 1024x768 format. I have no issue with this either.

This is my desktop as it normally appears in the 800x600 format. It doesn't fill the screen top to bottom.

This is my desktop as it normally appears in the 640x480 format. It it like looking at a postage stamp. I want to increase it (stretch it) to 1024x768. As in this example.

So far I am looking into fb, panning, and scale options without success.

Thanks for taking an interest.
