# Boot sequence:
#
# kdeinit is used to fork off processes which improves memory usage
# and startup time.
#
# * kdeinit starts the dcopserver and klauncher first.
# * then kdesktop is launched, it is started very early in the startup
#   process to give the user visual feedback as soon as possible.
#   Since it needs a working ksycoca database it waits for a
#   "sycoca database changed" signal from kded before it becomes functional.
# * Then kded is started. kded is responsible for keeping the sycoca
#   database up to date. When an up to date database is present it sends
#   a "sycoca database changed" signal.
#
# * The rest of the start-up sequence is less critical.
#
# kdeinit starts dcopserver, klauncher, kdesktop, kicker, kded and
# kwrited

# minutes until anything appears on the screen.

# people's heads. We use colours from the standard KDE palette for those with
