I have a Lenovo T520 with Nvidia Optimus graphics:
$ lspci |grep -E 'VGA|3D' 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev a1)
I managed to get it working fine under F29, but I don’t remember what exactly was the thing that worked. I’ve added bumblebee and rpmfusion at some point to the repos dnf uses and it also shows negativo17.
I noticed that Optimus no longer works because the DVI-Ports from the docking station are driven by the Nvidia card of the laptop and the DVI screen isn’t used after the upgrade to F30.
How do I find out which driver (nouveau, Optimus Prime, bumblebee, proprietary nvidia, …) is currently used? What’s the preferred way to get it to work again?
