I'm really new in this thing with ubuntu. I have this laptop X550JX(asus) and I don't know how can I set the brightness from keys. If anyone can help me it will be awesome. Thank you!

You can use Indicator Brightness applet. You can get it on Launchpad or install it from the ppa using the following commands in the terminal:

sudo add-apt-repository ppa:indicator-brightness/ppa
sudo apt-get update
sudo apt-get install indicator-brightness

After you install it, reboot your device. Then you can set the shortcuts to control brightness. Go to System settings -> Keyboard -> Shortcuts -> Custom Shortcuts. Add two shortcuts for the the following commands

/opt/extras.ubuntu.com/indicator-brightness/indicator-brightness-adjust --up
/opt/extras.ubuntu.com/indicator-brightness/indicator-brightness-adjust --down

Then you can assign your custom shortcut to them by clicking on the Disabled and pressing required keys.

  • Have you tried rebooting your device after the installation?

  • I did the steps again and rebooted and it's working now. Thank you a lot. It's pretty strange why isn't working with the "fn" key, because I can control the volume with FN+f11/f12 like in windows. Thank you again and have a nice day!

  • don't you know how can I fix the flash problem in opera? I tried almost everything I found on internet. The facebook videos are not working in opera but they do in firefox.
