[Gimp-user] Trouble using my trackpad/mouse in conjunction with Wacom tablet

[Stevobee <forums gimpusers com>]

Hi there,

I installed Gimp 2.0.4, then added my Wacom tablet as an input device, on a Mac
with OSX Yosemite, 10.10.5. My problem is that I can't control my stylus options
through my laptop's trackpad. If I select a tool or change the settings for a
tool with my trackpad, it changes the tool and its settings for the trackpad,
and not for the Wacom stylus ("Core Pointer" must be what Gimp calls a given
computer's default trackpad or mouse pointer). So if the tablet's stylus is
selected as a Paintbrush tool, I can't change paint colors for the stylus with
my trackpad--the only way I can change paint color for the stylus is if I use
the stylus itself to point-and-click through the dialog menus. This is really
difficult and frustrating because I keep accidentally tapping unintended icons
or changing slider settings as I hover my stylus just above the surface of my
tablet to tap on whichever item in whichever toolbox I'm actually trying to
select.

I've noticed that in some tutorials for setting up a Wacom tablet in Gimp, the
"Configure Input Devices" window lists the tablet devices as "WACOM Tablet
Eraser" and "WACOM Tablet Pressure Stylus". In others tutorials, the tablet
devices listed are Quartz Cursor, Quartz Eraser, and Quartz Pen. If it makes any
difference, Gimp lists them on my machine by the "Quartz" names. I tried closing
Gimp and reopening the whole program with the Stylus tip as my "pointer" instead
of the trackpad, as someone online had recommended, but this did not change the
listed input devices from "Quartz" to "WACOM". I've tried toggling the devices
on and off one by one (Core Pointer (trackpad), the Quwartz Cursor, Quartz
Eraser, and Quartz Pen) through Gimp's Input Devices window, and no sequence
I've tried seems to work. I've read about some users' pressure sensitivity not
working in Gimp, but mine works just fine.

My tablet has a "touch" option where if I use my fingers on it, it works like a
giant trackpad. Strangely, using this touch mode doesn't change the stylus's
settings either; it only changes the tools for the laptop's trackpad. I
uninstalled Gimp 2.0.4 today and installed 2.0.6 and that didn't make a
difference. What might be going on here? Any help would be greatly appreciated!
