From ac502c921d2e813e6e916a589a07bc58ca4c12e7 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Fri, 9 Feb 2018 11:53:17 +1000 Subject: [PATCH] backends/x11: wacom pressure curve is a 32-bit property The property has been 32 bits since around 2011 and has not changed, mutter expects it to be 8 bits. The mismatch causes change_property to never actually change the property. https://gitlab.gnome.org/GNOME/mutter/issues/26 Closes: #26 --- src/backends/x11/meta-input-settings-x11.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/backends/x11/meta-input-settings-x11.c b/src/backends/x11/meta-input-settings-x11.c index 7d1d360a3..9687fb36f 100644 --- a/src/backends/x11/meta-input-settings-x11.c +++ b/src/backends/x11/meta-input-settings-x11.c @@ -813,9 +813,9 @@ meta_input_settings_x11_set_stylus_pressure (MetaInputSettings *settings, ClutterInputDeviceTool *tool, const gint32 pressure[4]) { - guchar values[4] = { pressure[0], pressure[1], pressure[2], pressure[3] }; + guint32 values[4] = { pressure[0], pressure[1], pressure[2], pressure[3] }; - change_property (device, "Wacom Pressurecurve", XA_INTEGER, 8, + change_property (device, "Wacom Pressurecurve", XA_INTEGER, 32, &values, G_N_ELEMENTS (values)); }
