I'm running Fedora 8 with the Compiz-Fusion 0.6.0-x packages.
Unfortunately, I don't have the Magnifier plugin that you mention in
Ubuntu. I was able to see a demo of this on a YouTube video and it
appears to be exactly what I was describing.
I'm not suggesting a reinvention of the wheel or a duplication of effort
but I would really love to see this same feature as part of GNOME. My
reasons are primarily selfish in that I don't want to have to run
Compiz-Fusion just to see my Linux desktop and partly non-selfish in
that I don't see a need to have the same hardware requirements as
Compiz-Fusion just for the visually impaired to be able to use a Linux
Sound like you've used the basic zoom plugin - which is a bit rubbish
to be blunt...as it only zoom into a specific area of desktop but
There are two plugins that's to do with magnification:
Advanced Desktop Zoom - like Desktop Zoom, but does move around with
the mouse. However you see a part of the screen and so you'll have to
move the mouse around to see more.
Magnifitor (this seem to be new as I had just upgraded to Ubuntu Hardy
Heron and this shows up as an option now) - what this does is very
similar to what someone mentioned earlier - compared to Windows'
magnifior tool - once enabled, it shows a configuable window which
moves with cursor around the screen. Inside this window (it have a
black border around it) everything is magnified. Hope this description
is clear - it's not like Windows in showing a fixed window at top of

I essentially have two problems using Compiz-Fusion. First, it doesn't
seem to recognize my keyboard/mouse of choice, i.e. it does recognize
some of my other keyboard/mice. I use a KVM setup so I use a single
keyboard and mouse and have spent a lot of time and money finding the
one that works best for me. I really don't want to have to change if
possible. Second, the "Desktop Zoom" feature is "static". In other
words, it zooms in on a fixed, i.e. static, area. In trying to read
text on a screen I need it to dynamically move as I scan the text. It's
great in what it does but it does not lend itself to reading.
