I'm trying to get an Ubuntu laptop functional for a visually impaired friend. Her impairment is such that a screen magnifier would solve the issue. I've tried out Kmag (as its the only hit when searching the software center for "magnifier"), but it seems odd the Ubuntu lacks a default. So I'm assuming I'm missing something obvious.
To use magnifier in Ubuntu, you can do so by using CompizConfig Settings Manager. If you don't have it installed, you can do so from the Ubuntu Software Center.
Or, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.
Once you invoke the program, look under Accessibility for magnifier, and click on it to configure it.
O you can try Virtual Magnifying Glass 3.5
I'm visually impaired (I have Cone Dystrophy and thus my central vision is gone and I absolutely have to use full screen zooming to use a computer). This was my solution:
First of all, get rid of Unity and install the Cinnamon desktop; it's a much better interface anyway IMNSHO:
Once you have that installed, you can install Tobias Quinn's excellent gnome-shell-mousewheel-zoom:
This will provide Compiz-style mousewheel zooming functionality with Cinnamon.
Another alternative is to use Linux Mint which is an Ubuntu-based distro with Cinnamon built in by default.
If you choose this option, you simply have to add the Tobias Quinn PPA and install the gnome-shell-mousewheel-zoom package.
Canonical has abandoned visually impaired users and their actions are, to say the least, reprehensible and shameful. Every other OS creator provides quality full-screen zooming support for visually impaired users but since the advent of Unity, the actions of the devs of Ubuntu indicate that they no longer care about those users. I'll continue to use Ubuntu-based distros but Unity is now permanently on my "no-fly" list.
I am not aware of any default screen magnifier in Ubuntu.
In many applications you can hold
I have upvoted your question because I would also like to know of a better alternative to Kmag and I'm sure many other users would too, especially those in similar situations to your friend.
