<pre>Hi,
im using a new Lenovo Thinkpad P51 that uses Nvidia Optimus. It has a
integrated Intel graphic (Intel® HD Graphics 630) and a descrete Nvidia graphic
(Nvidia Quadro M1200). The Thinkpad is used in combination with a Lenovo
ThinkPad Workstation Dock (Docking Station).
My OS is Debian Buster (Debian Testing).
When using Nouveau and i915 as drivers while using both graphic cards, a kernel
error occurs (bios is set to hybrid graphics):
