Whenever the focus is on a text edit element, the key combination ctrl+alt+b brings up a weird on screen keyboard:
I wanted to remove this binding (or delete the program), but I can find neither! As you can see in the image, the OSK is not Florence nor Onboard, nor any I could find online. A reverse google image throws no results.
I'm using Ubuntu 14.04.3 LTS, with openbox as window manager, and no DE.

I had the same problem. Probably it's caused by fctix, which is some software, which supports input methods. For some reason, I couldn't successfully kill this process from terminal. I found it in graphical system monitor and killed the process from GUI. After that, while typing Ctrl+alt+B, weird keyboard wasn't displayed anymore. You can also try to remove this software.
Instruction showing how to remove fctix can be found here: http://installion.co.uk/ubuntu/precise/universe/f/fcitx/uninstall/index.html
