Linux Screen Magnification

Linux Screen Magnification

[Ray Campbell]

Hello:

This is my first post to this list.  I don't mean to get off topic right
away, but do any of you know of any kernel patches or software that runs
on Linux for screen magnification?

Thanks,

On the console, you can use SVGATextMode for larger text.

On x-windows there are quite a few alternatives, google
will lead you to them.

There is also czoom http://sourceforge.net/projects/czoom, however there 
has been no release for a while, and it is incompatible with speakup as 
it uses a sudo terminal to capture console output to magnify it.

I don't know of any such program, but there might be a neat way to 
accomplish the same thing without a program.

It is common practice to specify parameters for a text console other 
than the usual 80 by 25, although the available alternatives differ from 
one video card to the next. You change those dimensions within the 
lilo.conf file with a line that say "vga = xxx" where you have to find 
the proper value for xxx that matches your video card and your needs. 

Usually folks want more chars per line and more lines per screen. Mine 
is set to 132 by 60, and it is a terrific convenience. But what if you 
were to specify fewer than 80 chars and fewer than 25 lines? That would 
amount to screen magnification in a text console, seems to me.

I have seen examples of that being done in some manual or other, so it 
should be worth the trouble to hunt it up and pin it down.

And of course in Linux it's free and public.
