I have recently installed Ubuntu 14.04 in my Lenovo Z51-70. It has both integrated Intel HD5500 graphics and AMD Radeon graphics card. But when I run the command "lshw -c video", its showing only Intel graphics. How can I switch to AMD graphics?
EDIT
Output of lspci -k | grep -EA2 'VGA|Display' is
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)
