Rolling back Ubuntu updates is not exactly easy

In Ubuntu there are a number of ways to get upgrades. There is the update manager which is configured to run automatically. There is using the command line approach with apt-get ('sudo apt-get update && sudo apt-get upgrade'). Finally there is the GUI utility called Synaptic ('sudo synaptic').

So what happens when something gets updated and introduces a bug, or breaks another applications behavior?

Disable Blank Console Screens for Ubuntu

I have a number of Ubuntu servers that boot up in text mode (both VMs and physical boxes). Once they boot I usually access them via ssh sessions so almost never try to type to console directly. However, it is rather annoying to want to see what is being sent to the console because I have to click and hit a keyboard key. So I had to find a way to permanently disable the blank screen feature for the consoles.

Now when you are logged in this is simple to do just enter the command:

$ setterm -powersave off -blank 0
