My lenovo g500h has integrated intel 4000hd graphics card and discrete ati hd8750m radeon card. It looks like by default the intel graphics driver is installed ( when i type lspci | grep VGA in terminal, it says - VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09))
So how can i know whether linux sees my discrete card? And how can i know whether the amd drivers i find, are the right ones? I found these - http://support.amd.com/en-us/download/desktop?os=Ubuntu%20x86%2064 ,but it says its for Ubuntu 12.04.4 LTS
All in all, what is the overall process to install hybrid graphics on my PC? Where should i start? I spent some time earlier on this, but couldn't find any good aggregated information.
