Brightness control on my laptop does not work, how can I diagnose if it's unsupported, or a bug? And if it is a bug, what do I include in the bug report?

UPDATE

Thank you for all the responses, specially @Guandalino for the bounty. But unfortunately the laptop in question is no longer functional due to an accident involving water. And as such I cannot actively participate and try the out the potential solutions.

Those still interested in this question, please participate in this discussion at Ask Ubuntu Meta.

Check or dig around your laptop vendors website to see if they have any useful information relating dianosing the control.

If the vendor has forum, try seek information there also. Please add your laptop model detail as part of the post so we know which product and model you are seeking support on.
