From 8795feb644c38f4cdae882e3cea934c7ec996661 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Wed, 19 Apr 2017 22:20:19 +0200 Subject: mb/lenovo/t420: Enable libgfxinit In the single GPU configuration, the T420 has an LVDS port, one DP++ and one VGA port connected to the IGD. Docking solutions feature up to two additional DP/DVI-D ports, also directly connected to the IGD. This makes the list of ports to probe pretty long (takes about 70ms if nothing but LVDS is connected). We could save about 20~30ms if we'd limit the ports in case we are not docked or have a discrete GPU.
