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 :
- I can't adjust the brightness in my laptop with the shortcut keys or setting the brightness otherwise
- 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?
