is there a wasy to have the monitor sleep with an icon on gnome or xfce4 or script that puts the monitor to sleep without having to wait for the normal time to expire? like at end of day. i still want the 20 min before off during the day

with xscreensaver, you can start it straight away (can't remember the command, try man pages), so presumably if you set it to blank the screen with no screensaver, then you can create a button for it and just have it run the command ('xscreensaver -now', or whatever it it...)
