Accessibility

The Negative plugin provides immediate, high-contrast windows for the visually impaired by inverting the colors of individual windows, or all windows at once.

<!> This plugin requires that you have the GL_ARB_fragment_program extension. It must be available with your graphics card, and your X Server must expose it.

Usage

Enable/Disable [Focused] Window Negative

<Super>n

Enable/Disable Screen Negative

<Super>m

Configuration

Window Matching is used to determine which windows are affected or unaffected by Negative:

  • Neg Windows - By default, any (ie. all) focused windows will be affected.

  • Exclude Windows - By default, only windows of type=Desktop are excluded from the effect.

Workaround if unsupported

xcalib can be used if the "Negative" filter is not supported by your hardware or driver. To invert the screen palette with xcalib:

  • xcalib -i -a

Please note that xcalib is not part of Compiz Fusion.
