Problem:
- some of the video display display is unused by the graphics driver
- two displays are detected when only one physically exists

Additional details:
- the correct native resolution is used in Windows:  1680 x 1050
- there is no external VGA/HDMI/DVI connection to connect an external monitor

I have tried using xrandr and my own modeline, such as this (without success):

- note that once this setres.sh script is run, the screen geometry available to the window manager appears correct, but the graphics memory is not being addressed; the panel menu is displayed in the correct position now, but the graphics memory is clearly not being used as the same screen garbage/artifacts show over the video.  Also, I can now move the mouse pointer into the garbage/artifact area on the right margin, although the mouse pointer disappears, I can tell by movement that the pointer moves over to the correct edge of the display and takes what seems like the correct amount of time to track back into view.
