For some general updates:

For the Banshee media player:
First run this:
xinput list
You will get something like this:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Primax Electronics Dynex Wireless Optical Mouse id=10 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)] ⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Laptop Integrated Webcam id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]
One of these will be the device you want to disable. In this case, the AlpsPS/2 ALPS GlidePoint has ID 13, so I run:
xinput set-prop 13 "Device Enabled" 0
and it’s done!
