Hello, forum users!
I have a laptop Samsung 300v5a-s19 with NVIDIA GeForce GT 520MX.
I have just installed Ubuntu 12.04.1 and then Bumblebee 3.0.1.
Now it works well without any lags, but there is one problem: when I try to change the screen brightness (by Fn buttons or in the System Settings (Brightness and lock)), display starts flickering. That is, I can not dim the screen.
Does anyone know what the problem is and how to solve it?
Thanks for your aid.

I found one more problem: screen starts to twinkle if charger is not plugged in to laptop. It doesn't start immediately, but several minutes later.
What can it be?

Hi, every Samsung laptop users!
I think, I found the solve of this issue.
To stop flickering of your display you should install samsung-tools package:
sudo -s
add-apt-repository ppa:voria/ppa && apt-get update && apt-get install samsung-backlight samsung-laptop samsung-tools
reboot
After this you will enable to dim your screen back-light =)
Hurrah!
