Installation

Use the Installation guide. Make sure that Secure Boot is disabled in the BIOS. For video output on Xorg see the Xorg configuration section.

Configuration

Xorg

The Intel device needs to be specified in the Xorg config. Create the file /etc/X11/xorg.conf.d/20-intel.conf with the following contents (or add it to your /etc/X11/xorg.conf).

Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   BusID "PCI:0:2:0"
   Option "TearFree" # Not required but helpful
EndSection

Bumblebee

Bumblebee seems to work fine with the proprietary NVIDIA drivers. Follow the Bumblebee instalation guide. You might need to set the PCI bus (showed in lspci) in /etc/bumblebee/xorg.conf.nvidia.

Prime

PRIME doesn't seem to be working properly. The 3D device shows use as the Quadro P500 but performance is the same as the Intel GPU. Not sure what's going on there.

Nvidia-xrun

Nvidia-xrun seems to be working properly, even with Bumblebee set up. To use it you just need go to other tty and run nvivia-xrun.

Smartcard reader

For the smartcard reader to work you need to install pcsclite. You can test it with sudo pcsc_scan (you need pcsc-tools installed).
