== Enabling logging
i3 spits out much information onto stdout. To have a clearly defined place
where logfiles will be saved, you should redirect stdout and stderr in
xsession. While you’re at it, putting each run of i3 in a separate logfile with
date/time in it is a good idea to not get confused about the different logfiles
later on.

When i3 crashes, often you have the chance of getting a 'core dump' (an image
of the memory of the i3 process which can be loaded into a debugger). To get a
core dump, you have to make sure that the user limit for core dump files is set
high enough. Many systems ship with a default value which even forbids core
dumps completely. To disable the limit completely and thus enable coredumps,

When debugging with us in IRC, be prepared to use a so called nopaste service
such as http://nopaste.info because pasting large amounts of text in IRC
sometimes leads to incomplete lines (servers have line length limitations) or
flood kicks.
