Question.  The framebuffer bit depth can be set after Ubuntu has started, by using the fbset utility on the command line. If one wants a bit depth, resolution, or refresh rate to override the default on startup, it has to be included on the kernel command line using the "video" parameter.

 

Answer.  To specify the display framebuffer characteristics on the kernel command line, use the "video" parameter in the following format:

 

video=mxcfb:resolution-bitdepth@refresh

 

For example:

 

video=mxcfb:1024x768-24@60

 

sets the framebuffer to 1024x768 resolution, at 24-bit color depth, and 60Hz refresh rate.
