[Bug 766490] Re: [Natty-Beta2] Turning off laptop monitor turn off both monitors (laptop and external) on Vostro 3500

 

Closing as expired since it has been several months waiting for
information.

It's likely the newer kernel in precise does not  have this bug.

Title:
  [Natty-Beta2] Turning off laptop monitor turn off both monitors
  (laptop and external) on Vostro 3500

Status in “gnome-control-center” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: gnome-control-center

  Following instructions for testing external monitor on a laptop in http://testcases.qa.ubuntu.com/Hardware/GFX/ExternalPrimary
  the resolutions of the external monitor are not detected properly. When I try to change them, also the Laptop Screen flickers and changes sizes (with "same image" option disabled, of course).
  Worse is when I try to set the external monitor to be primary (by turning off the laptop screen), both screens turn off.
  My steps:
  # Plugged external monitor
  # Go to Monitor in the Unity launcher.
  # Both screens are detected.
  # Tried different resolutions and more or less some of them worked (there where some resolutions external monitor isn't capable of).
  # Selected Laptop monitor and switched off, click apply.
  # Both monitors turned off and had to wait for the 30 second dialog to restore the last configuration. I was hoping the laptop screen to turn off and the external monitor be the primary.

  Then tried the switch screen har-button in this laptop (Fn + F8) but it triggers a "super" key instead (like the win logo).
  Afterwards Compiz crashed (Bug #766496).
