Samsung R540 Screen Brightness Issue
Posted: 08 Jan 2012, 22:03
Hi,
I use Ubuntu 10.04 on Samsung R540 which has ATI Mobility Radeon HD 4500 Series graphics card. However, I cannot control my screen brightness using fn+up/down key combinations. I also tried the GNOME Brightness Applet, it didn't work either.
Can you help me about this?
Thank you.
