The problem seems to be that in compiz 0.9, a lot of code related to OpenGL has changed.
More details here: http://wiki.compiz.org/Development/zero- nine/GLESPorting THe part releveant to the color filter plugin is: "ARB Assembly Program Usage As GL_ARB_fragment_program is not part of the OpenGL core profile or OpenGL|ES, it was removed in favor of GLSL shaders. Unfortunately, that means that any plugin that uses GLFragment to generate GPU assembly shaders needs to have that part rewritten. That warrants another article as it is a much larger subject." So, someone needs to write a color-filter plugin that doesn't use ARB syntax. It needs to take GLSL shaders as input. For my part, I will try to write a simple plugin that only filters color channels based on a percentage value. For example: if the percentages are (100, 40, 40), then the resultant color would be (r, g*0.4, b*0.4) -- You received this bug notification because you are a member of DX Packages, which is subscribed to compiz-plugins-main in Ubuntu.

Since Quantal however, the plugin is not present: http://packages.ubuntu.com/quantal-updates/i386/compiz-plugins-main/filelist This is an important plugin for the following reasons: 1. Some people have a medical condtion that makes them sensitive to certain colors. 2. For anyone who needs to work at night, or work in a low light condition, it is often useful to filter green and blue light.
