So I finally dual booted Windows 10 with Ubuntu 16.04. I have been running Xubuntu on my secondary laptop around 5-6 months and now decided to install it on my main laptop so far Ubuntu runs great but there's only one issue: I can't see my dedicated GPU [AMD Radeon 8670M] it only shows my Intel Integrated GPU [Intel HD Graphics 4400]. On Additional drivers section there are only Intel Proprietary Drivers.
Here are the Commands I ran :
$ sudo lshw -c video

computer see card but is switching from card to integrated graphics,for some reason..note a line →
" switching to inteldrmfb from VESA VGA "
So further steps are obvious,look on this site or else for →How to switch from integrated graphics to dedicated graphics. There are commands for that. And "lspci" command can confirm that card is seen. Waiting for confirmation of "that card is seen" with output of command " lspci | grep VGA " (type in terminal one or both lspci commands without ")and post results here.
