# website advises installing xsceensaver
# but this would pull in a huge list of dependencies,
# apparently including much of gnome2.

# 'xset s noblank' results in being logged out completely,
# terminating any applications that were open, including xterm;
# It is supposed to display a pattern instead of blanking the screen.

# 'xset s 600 60' sets timeout period to 10 minutes
# The second number sets the period for which each pattern is displayed,
# if the "noblank" mode is set.
# It will be necessary to issue this command after every login.

# 'xset q' lists all settings.

# For Raspbian-lite 9 Stretch (as on rpi3), add 'consoleblank=600'
# to the end of the line in the file /boot/cmdline.txt
# to set a timeout of 10 minutes.

# Console-blanking seems to be turned on by default
# in Raspbian-lite 7 Wheezy (on rpi1).
