Disable Console Power Save on Ubuntu

By default Ubuntu console turns off after about 15 minutes of no keyboard commands, regardless of what may be, being displayed at the time. Often it is useful to disable this ‘feature’ on production servers to better monitor the activities being sent to the console, such as errors and logs.

There are two methods of doing this, either per session, or for the whole system.

To disable it for only the current session log in as root run the following command:

setterm -powersave off -blank 0

To disable console blacking for all session on this server and to retain this change after reboot, you will need to start by installing the console-tools packet:

apt-get install console-tools

After you have the console-tools packet installed. To stop the screen blanking both the screen saver (BLANK_TIME) and the power management standby (POWERDOWN_TIME) settings need to be disabled. If these two settings are set to zero (0) in the file /etc/console-tools/config the features will be completely disabled.

Alternatively a local settings file called /etc/console-tools/config.d/disable-blank-console can be created containing the following two lines to achieve the same affect.


Actually you can name the file anything you want so long as the name consists of only upper/lower case letters, numbers, underscores, and hyphens.

Using the Git Stash command

The git stash command is used to store changes to a dirty git tree when pulling changes[ref]http://man.github.com/git/git-stash.html[/ref].

For example, if you are working on a repository, but are not ready to commit your changes, you may run.

git stash

This will store the changes you have made since the last revision and allow you to start back fresh at the point of your last commit.

Once you are done, you may run

git stash pip

That will restore your repository back to where you were when you ran git stash.
