Do you mean your console or your graphics display is flickering?

If it is your screen that is flickering i suggest you check the refresh rate being using against the spec of your machine: System -> Preferences - Display
Mine is set to Auto, in your case you may to override it.

It is the graphics display I heard someone wrote to me and they said that the flickering has to do with the power mangement is this true?

Flickering is normally caused by a configuation problem, more often that not, the configuration error is in the refresh rates.

For example, see this and/or this Google search.

This is one of those annoying problems which I cannot solve in 9.04.
I had no problems with 8.04 before.
In fact I posted a couple of messages on these other boards the other day about this problem.
I hope they come out with a patch because they have made Ubuntu 9.04 similar to MAC where we as the users do not have an easy way of customizing anything, it is a package deal and if you dont like it, TUFF!
(this has been my take, of course I am no expert..)

But the xorg.conf has become almost obsolete and then in GUI you dont have any control over the driver settings?!
I think that is terrible.
In any case as you probably already know, in older versions of Ubuntu you could use different refresh rates (as some 1 already said) and raise it from like 60 Hz to 70 (or vice versa) and take care of the problem. But I have not found any solutions yet.

Did you try using different refresh rates in System>Preferences>Screen Resolution?
