From abbe3acd7d72ab4633ade6bd24e8306b67e0add3 Mon Sep 17 00:00:00 2001 From: Cole Rogers Date: Mon, 1 Jul 2019 00:47:48 -0700 Subject: [PATCH] Input: synaptics - enable SMBUS on T480 thinkpad trackpad Thinkpad t480 laptops had some touchpad features disabled, resulting in the loss of pinch to activities in GNOME, on wayland, and other touch gestures being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids whitelist to enable the extra features. In my testing this does not break suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while also fixing the feature on a T480.
