Python Commands from Terminal Aren't Working Ubuntu 13.10 I'm fairly sure I'm doing something wrong and this isn't a bug, but when I installed blender from the 'blender' repository and have 2.66a running in an Ubuntu 13.10 VM, I got problems with using Python in the console.
After starting blender I get the following warnings:

Color management: using fallback mode for management
connect failed: No such file or directory


After this when I try to type in any Python commands at the terminal, nothing happens.  The &gt;&gt;&gt;, suggesting an interactive Python session also don't appear.

What am I doing wrong?
As mentioned by sambler, the terminal from which blender is started is not normally used as an interactive python console. (however it is possible)

Usually one uses the python console built into the GUI.

The python console is an editor just like the 3D view or the text editor, so you can arrange your screen layout however you like to incorporate it with your workflow. 

For example:



You can even split an editor into a separate window (as in the kind handled by the window manager).
This can be accomplished by pressing ShiftLMB on the area splitting corner and dragging, or by selecting the option from the editor areas menu:



For example:



Note that you probably still want the terminal from which blender was started open, as any error messages/warnings are printed to stdout and will appear there  (they will not appear in the interface by default, but there is a workaround).
