I played with HAL and the GIMP "input controllers" preferences trying to map
my device, but so far I had no luck. The GIMP prefs are indeed beautiful
and still give me hope on having this solved with no code at least on Linux.
So, after building GIMP I noticed the presence of a "Linux Input" entry
under the available controllers. I added that to the Active list and I even
saw a "3Dconnexion SpacePilot" entry under the Device list. However when I
select that, GIMP tells me the State of the device is "not available:
Permission denied". Our evil proprietary driver is not running and AFAIK no
process is claiming the device.
from HAL Device Manager:
linux.device_file = /dev/input/event6
# lsof | grep -i input | awk '{print $1"\t"$8$9}'
Xorg /usr/lib/xorg/modules/input/synaptics_drv.so
Xorg /usr/lib/xorg/modules/input/mouse_drv.so
Xorg /usr/lib/xorg/modules/input/kbd_drv.so
Xorg /dev/input/mice
Xorg /dev/input/event9(deleted)
hald-addo /usr/lib/hal/hald-addon-input
hald-addo /dev/input/event5
hald-addo /dev/input/event4
hald-addo /dev/input/event3
hald-addo /dev/input/event1
hald-addo /dev/input/event0
lt-gimp-2
/home/ep/svn/gimp/builds/main/lib/gimp/2.0/modules/libcontroller_linux_input
.so
In HAL, I also noticed the default is that "input.mouse" is actually added
by default to the info.capabilities list of our device, so I can actually
move the mouse pointer with it. Could that be it, interfering with GIMP?
(BTW I don't want to move the mouse pointer.)
So I went ahead and created my own .fdi file, first just adding
input.joystick to the list (made sense) but no changes. Then I removed
"input.mouse" and had input.joystick only, however in this case GIMP doesn't
see the SpacePilot device entry anymore. Why?
If anybody can shed some light on this I'd really appreciate it, it seems
like everything is already there (if only I could manage to "trigger" it).
Thanks.
Ettore
