Blank screen while Yum updating and skipping

Question

This question maybe is going to sound nonsensical and stupid but all these things are new to me and I'm always afraid that something is going to be wrong.

I recently started using CentOS and before I do any settings, I want to update my system. The embarrassing thing is that when I call from console as root user

yum update

The system starts updating and said that it got 200 and more modules to update. I confirm that I agree with that and the update process starts correctly.

On the screen I see the progress and after a while the screen goes blank, power saver turns it off.

When I hit any key on the keyboard, the screen goes on again but the current downloading transaction does not go to 100%; the update process simply goes to the next transaction.

Now I'm wondering what will happen with the transaction which is not finished until 100%.

Is that module going to be updated correctly?

Answer 1

CentOS times out the screen by default on the console. That's normal. You shouldn't use enter as a means to wake it up, as it will put enter on the input buffer and the next time yum asks you for confirmation, you might be selecting a default option.

I think CentOS has a mouse driver, so wiggling the mouse to wake up the screen is a better approach. Otherwise use a key like "a". =)
