power saving for smarter planet

Hi All,

I usually lock my screen when I leave my cubicle for a tea-break etc.
With all the awareness for saving Energy etc. etc. I have disabled screen-savers on my system.
Still when I lock my screen I noticed that the LCD doesn't turn off completely.
Then I wanted to save even that little bit of light emitted i.e. wanted to switch off the LCD.

This command helps us do that :
xset dpms force off;

and this is the command invoked when I press "Alt+Ctrl+l" to lock the screen :
gnome-screensaver-command --lock;

Then, I wanted to associate the following command to a shortcut key:
gnome-screensaver-command --lock; xset dpms force off;

So that I can lock as well as power off my LCD screen with a keyboard shortcut.

So, I installed xbindkeys to add a custom shortcut key:
sudo apt-get install xbindkeys
"gnome-screensaver-command --lock; sleep 1; xset dpms force off;"

created the default config file :
xbindkeys --defaults > /home/your-user-name/.xbindkeysrc

Then to assign a shortkey, you can either edit this file manually or do it through xbindkeys-config(sudo apt-get install xbindkeys-config).
I removed the default enabled lines (somehow they interfered with my other shortcuts) from ~/.xbindkeysrc and appended the following lines :

"gnome-screensaver-command --lock; sleep 1; xset dpms force off;"

I was forced to give a "sleep 1" between the two commands; else it was not working ... maybe because of compiz animation time.

Now, when I press "alt+control+k" I save power as well as lock my screen.

Spread this word and let's save energy, so that our grand-children are not forced to lead a life in dark.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
