Bug Description

After upgrading to Gutsy Gibbon on an emachine s-1940 the power management does not work correctly. I have it set to never shut down the monitor but after appropriately ten minutes the screen powers down. As soon as I move the mouse the screen comes back alive.

The same. Laptop - Dell Inspiron 1501.

I fixed this with adding the following to xorg.conf:

Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"

But I think it's just a workarround.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The package your reporting is updated and the issue should be reproducible with the live environment of the Desktop CD development release - Maverick Meerkat. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find more about the development release at Thanks again and we appreciate your help.

Can you still reproduce this with a supported Ubuntu version? Thank you!
