LCD monitor attached to laptop flickers

[Carla Sella]

Binary package hint: gnome-control-center

During Testcase: http://testcases.qa.ubuntu.com/Hardware/GFX/ExternalPrimary on my laptop ( HP-G62), after having connected my laptop to an external Acer AL1715 LCD monitor, and having disabled the laptop monitor, the image on the Acer LCD monitor stared flickering in a quite unbearable way.
Before disabling the laptop monitor, the image on both the LCD monitor and the laptop one was fine.

Please could you check if this behaviour is still occurring with the latest release 2.32.1-0ubuntu15 included in Ubuntu Natty Narwhal? Thank you

I confirm it doesn't happen anymore on the latest release of Natty.
