Screen blanks on lid close - Powermanagement is set to "Do nothing"

[Emil Orloff]

I'm using Ubuntu 10.10 the Maverick Meerkat, on a dell Studio 15 laptop with a Mobility Radeon HD 4500 GFX.
My problem is that whenever I close the lid of the laptop the screen blanks. This is a problem when I'm using the laptop with an external screen and I need to close the laptop in order to store it away.
In power management, the setting is set to "Do nothing".
If there is anything else you need to know, just ask!

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer the question:

* The external screen blanks too when you close the lid, not only the laptop display?
* Are you using the opensource or the proprietary ATI driver?

This will help us to find and resolve the problem.

* Yes, the external screen blanks too.

* I'm using the opensource driver. I have tried the proprietary ATI driver, but it didn't work either, so I switched back to the opensource version.
