Raw Blame History

From 6f79f4993d351a891a715e994ab9574542e64b35 Mon Sep 17 00:00:00 2001

Subject: [PATCH xserver 09/12] xwayland: add tablet pad support
Hooked up a bit differently to the other tools. Those tools can be static for
all and be re-used. The wacom driver initializes the pad with the correct
number of buttons though and we can't do this until we have the pad done event.
If the tablet is removed and we plug a different one in, we should initialize
that correctly, so unlike the other tools the pad is properly removed and
re-initialized on plug.

(cherry picked from commit 8475e6360ce31551d50fd63a26f7a44d1e8928f2)
