After install nvidia drivers 304.131 or 361.42 from -Software & Updates>Additional Drivers-. I have to say It was working before with Nouveau.
when I do click above the buttons they do nothing.
I only can use the keyboard, e.g. for pause I use p key or space bar.
Pc especifications:
motherboard: intel DH87RL
memory: 15.5GiB
processor: intel core i5-4430 3.00GHz x4
os type: 64-bit Ubuntu 16.04 LTS
graphics: GeForce GT 610/PCIe/SSE2
driver: Nvidia legacy binary driver-version 304.131
how we can solve this?
You have to test more nvidia drivers, all you have on hand. As in my case none worked I had to install this ppa for more drivers "graphics-drivers/ppa". More information here.
Open your terminal:
After that you can test more drivers, for example the 367.44 and check if it works. In my case this solve my problem.Software & Update image
