I have Lenovo G40-45 Laptop with specs :

  • AMD A8-6410 Processor
  • Radeon R5 M230

I use Ubuntu Gnome 14.04 LTS for the operating system, overall almost my laptop work properly with Ubuntu, but I found an issue with my laptop :

  1. I can't adjust the brightness in my laptop with the shortcut keys or setting the brightness otherwise
  2. I think my battery is draining faster than my other OS (Windows 8.1) and also I think my laptop is overheating with Ubuntu, whereas it's not problem in Windows 8.1

I originally had the same issue adjusting brightness in Windows 8.1 too, but I solved that with installing an AMD driver for Windows here

How should I proceed?


I have the same model of Lenovo laptop. I achieved the battery life last longer with this guide in Spanish. The battery have the same performance than Windows 8. http://www.taringa.net/posts/linux/18073964/Optimizacion-de-energia-Dell-Inspirion-5521.html
