I have dual graphic in my laptop AMD radeon 7670M And Intel HD After I installed Ubuntu 16.04 Fan speed is quite high and my laptop lags whenever I view videos on browser or open Facebook Is it due to the AMD drivers no more supported in 16.04 Can I disable AMD and use only Intel

I have dual boot and I use Ubuntu for development stuff so is it possible to use dual graphics in Windows while using only Intel in Ubuntu ?

Is it good to turn off the AMD and will it decrease the noisy fan and the lags I face

Yes, you can deactivate the AMD graphics and just use only the intel graphics without problems.

In case you have not already installed it before - install the gksu package from the repositories.

Open a terminal and execute : 

sudo apt-get install gksu

Now execute this command : 

gksudo gedit /etc/default/grub

Add radeon.modeset=0 to this line : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

so that it reads : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"

Save the changes you made.

Then execute this command : 

sudo update-grub

Reboot the system and from now on you are using the intel graphics ... and AMD is deactivated.
