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.
