I recently dual booted my Windows 8 with Ubuntu 13.04. The first thing that came to my notice was that the brightness was too low. I increased the brightness to maximum from system settings, but still, it remains low. I did not face any such issue with Ubuntu 12.10 that I had earlier.
Graphics Card: ATI Radeon 7730M
Laptop Model: Dell Inspiron 15R Turbo
So, is there a way to increase the brightness to the actual maximum?
