I have upgraded my ubuntu to 12.10 and installed CompizConfig Setting Manager to do some custom settings and one of the is enabling Magnifier Box. But this doesn't work, i have tried many shortcut combination but it still does't work.
Is there any compatibility issue with this feature or what? please let me know if there is a trick or an issue.
The Magnifier Box will magnify some area withing the box or with an image overlay.
