To be able to perform any X operations, you must first establish a
connection to the display. This is done by instantiating a
display.Display
object:
Create a connection to the display called displayname. If displayname is None or not provided, connect to the default display.
If the connection fails for some reason, one of the errors from the following error class tree is raised:
Exception \_error.DisplayError \_error.DisplayNameError \_error.DisplayConnectionError
error.DisplayNameError
is raised if displayname, or the
default display name, is malformed. error.DisplayConnectionError
is raised if the connection to the X server fails. This might be caused
by the network connection to the display failing, or if the client
isn't authorized to connect to the display.
The syntax of a display name and how the library finds the default display name depends on the operating system where the client runs.
