I am trying to figure out how to automatically switch to the Equinox Evolution Dawn, Light, Dusk, and midnight theme at the appropriate time of day (ie; at 6 a.m. it would switch from midnight to dawn, at 8 or 9 it would switch to light, 7 p.m. would switch to dusk and 10 p.m. switch to midnight)

I am trying to do this using cron, with the following crontab:

0 6 * * * gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-dawn'

0 8 * * * gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-light'

0 19 * * * gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-dusk'

0 22 * * * gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-midnight'

This is not working. I am using ubuntu 10.10 with Compiz as window manager

Not a precise answer to your question, but you might see Gnome theme which changes depending on the time of day – belacqua Apr 11 '11 at 17:19
What do you mean by "not working"? No part of the theme changes? – Alvin Row Apr 11 '11 at 22:12
That's correct. No part of the theme changes in any way that I can tell. – user3403 Apr 11 '11 at 22:35

Can you try this script? (adapted from New Wave -Chronos)

# Autor: Narf SS 2009
# Site:
# Este script cambia el archivo de configuración del tema metacity "New Wave Chronos"
#y actualiza el tema.
#Para su funcionamiento (sin modificación) debe de ser añadido a la ejecución en el inicio, 
#y el tema debe de estar instaldo en la carpeta ".theme" del home del usuario.
#Y por supuesto seleccionado en la apariencia del escritorio y este mismo script añadido a las aplicacioens de inicio.

while [ true ]
    hora=`date +%H`

    case "$hora" in
    06|07)          # Amanecer
        gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-dawn' ;;
    08|09|10|11|12|13|14|15|16|17|18)   # Medio dia
        gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-light' ;;
    19|20|21)               # Atardecer
        gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-dust' ;;
    22|23|24|00|01|02|03|04|05) # Madrugada
        gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-midnight' ;;

    sleep 1h

That successfully changes the metacity theme, but not the GTK or icon themes...where would I find the commands for changing those, and how would I insert them into this script? – user3403 Apr 12 '11 at 5:01
Just add something like: && gconftool-2 --type string --set /desktop/gnome/interface/icon_theme 'theme_name' after every gconftool-2 --type=string --set /apps/metacity/general/theme 'equinox-evolution-dawn' – desgua Apr 12 '11 at 14:35
It now works correctly, had to do a few tweaks to the script because I had some of the theme names off and, in the case of the Light one, the metacity theme was actually Equinox Evoluution Rounded – user3403 Apr 12 '11 at 23:31
-----Nice!----- – desgua Apr 13 '11 at 0:12
