Update: I have tried to install the drivers again, using the rpm fusion, just like hedayat said, but I had the same problem. So I could fix this time by running yum remove xorg-x11-drv-nvidia\* This tutorial (http://rpmfusion.org/Howto/nVidia) says that by the command /sbin/lspci | grep VGA I can discover my graphics card model, but the the return is: *00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) * Is that right?
