From 4a96a58f2693b291b91e21b7e34f5c5e04015f3f Mon Sep 17 00:00:00 2001 From: Jason Gerecke Date: Tue, 3 Oct 2017 13:45:37 -0700 Subject: [PATCH] Add support for kernel's new BTN_STYLUS3 event BTN_STYLUS3 was (will be) added to the Linux 4.15 kernel to support the third button present on Wacom's "Pro Pen 3D" stylus. This commit adds support for this new event, mapping it to mouse button 8 ("navigate back"). Remapping this button to a different function is possible by using commands like `xsetwacom set button 8 `.
