Xorg server settings - shrinking the diagonal of visible screen
Thomas
Sorry for little offtopic, but the Xorg and X window related usenet's
groups are almost dead.
As in topic, I looked for how to change the diagonal of X screen size. I
want to have my 19'inch lcd to run of the size of the 15 of 17 ' inch
size, i.e. to have black borders and the screen centered. I looked at
serveral places to do that , but nothing found. The reason I want to do
that is I am rather poor sighted and I found the smaller lcd at my
university department to be more suitable to me.
I just cannot / have no time to dig deeply into documentaion/sourcecode
of Xorg server to do that.
I am running slackware 13 current with xorg-server-1.6.3.
Cheers all.

You almost certainly do not want to change the image SIZE. If you display
a 15" image on a 19" panel with black borders, the icons and the text will
be exactly the same (small) size as they were when the image was full
screen.
You want to change the RESOLUTION -- the number of pixels. Your 19" panel
is probably using 1280x1024 (or bigger) You can change that to 1024x768 or
even 800x600, if you find that more comfortable. In most modern Linux
distributions, there is some kind of a control panel or settings dialog for
the display that will let you change the screen resolution.
This has its own set of problems, however. With a CRT, the pixels don't
ever align precisely to the color bits on the screen, so when you reduce
the number of pixels, you don't notice it getting mushier. With an LCD,
there is an "optimal" resolution where the pixels line up exactly to the
LCD dots. When you reduce the number of pixels, they don't line up any
more, so the image gets fuzzy.

Unfortunately, that's a poor way to ask a question if you expect to get an
answer. The reason they WRITE the documentation is to tell you how to use
the product.
