One used to be able to increase the size of everything by changing the screen resolution on the fly with CTRL+ALT++ or CTRL+Alt+-. The shortcuts would circle through all the resolutions specified for your current colour depth in /etc/X11/xorg.conf.
On my gnome it's the Ctrl++/Ctrl+- combination(s) which zoom in/out, but that only works with certain apps (e.g. it does with lo-writer and firefox but doesn't with medit). And it also only provides 6 levels of zoom, which is the same as Ctrl+Scroll-wheel - too few for my requirements (assume these are the resolutions you referred to).
No, they are not. CTRL++ zooms in without
changing the screen resolution, so it does not reduce sharpness of the display, but it only works in some programs, and it only changes the resolution of one window at a time.
CTRL+ALT++ zooms in by changing
the resolution of the whole screen; it makes everything
larger and blurrier. And it does work in Gnome too - but not well enough. (I had to install Gnome just to check. It works precisely as in KDE, but the resolutions it toggles between won't serve your purpose. You need a much larger zoom factor.)
On the other hand, magnifying everything on the screen by lowering the resolution is a very bad idea these days: on a flat-screen display anything but the monitor's native resolution will give you a less sharp picture.
I agree, but my friend is very severely sight-impared, so some loss of sharpness is something she's prepared to accept if it helps being able to read at all.
I'll keep looking, perhaps I can find some other solution.
Thanks, once again .
I think you should first of all change all default font sizes. But as I don't run Gnome I cannot really help you here. I know how to change some of them, but I don't know how to change all of them.
You could begin
by starting the Gnome configuration editor; then navigate to /desktop/gnome/interface/font_name
, and change the value from the default "Sans 10" to "Sans 40". And then you could do the same thing to document_font_name
. And after that? To continue you may need the help of somebody who really uses Gnome.
