Well, Knoppix managed to hide the pertinent control program pretty
well. It took me several minutes to find it, and I knew what I was
looking for. Frequently the automated display setup chooses something
weird that does not fit your monitor.
Circle K -> Control Center -> Peripherals -> Display -> Size & Orientation
will tell you what it thinks you have and should let you make changes.
Probably you can change Screen Size and Refresh rate to suit your
monitor better.
Try 1280x1024 and 60 Hz for starters.
Also see if your monitor has a setup button that will align it to the
input signal.

The current setting was 1280x1024 at 75 Hz. There was no dropdown
choice for 60 Hz
I changed to the next lower value, which was 1152 x 864 at 60
Hz. Result: the blank area at the left went away. I then figured
out button to auto adjust. That also fixes problem. Thanks.
