A.3 Enabling Full Screen Magnification in Gnopernicus

To enable full screen magnification in Gnopernicus, perform the following steps:

  1. Configure two video cards as :0.0 and :0.1.

    Note –

    It is not essential that both video cards have the same resolution and bit depth. However, if the resolutions and bit depths of both cards differ greatly, the apparent magnification factor may differ slightly from the nominal magnification factor.

  2. Click Launch, then choose Applications -> Accessibility -> Screen Reader and Magnifier to start Gnopernicus.

  3. Click on Preferences.

  4. Click on Magnifier.

  5. Click on Add/Modify.

  6. Specify :0.0 as the Source for magnification.

  7. Specify :0.1 as the Target for magnification.

  8. Set the Zoomer Placement to be [0,0,1023,767].

    Note –

    These instructions assume a video resolution of 1024x768.

  9. Restart Gnopernicus. The magnified view is displayed on the second display 0.1.
