[Bug 858046] Re: 11.04: external monitor not working from laptop

 

apport information

** Tags added: apport-collected oneiric ubuntu

** Description changed:

  Upgraded to 11.04 My laptop won't redirect output to an external monitor
  or a projector via the Fn+F8 key combination.  This worked under 10.10
  My laptop is a Dell Vostro 1400 laptop with a GeForce 8400M GS display
  card installed.
  
  The Ubuntu Display control panel won't detect a second display when the
  "Detect monitors" button is clicked. It also can't detect the laptop's
  own display type and labels it as "Unknown". Using the Nvidia X Server
  control panel, I can see that the laptop's display is a Seiko/Epson
  panel and, when I click the "Detect displays" button I do get the second
  display (a flat panel monitor),but it is labelled: "CRT-0 disabled".
  
- I've activated the drivers in the "Additional drivers" panel twice and
- used Synaptic to run Nvidia-update (followed by a restart). I still have
- "This driver is activated but not currently in use" in the Additional
- Drivers control panel plus, in the header, "No proprietary drivers are
- in use on this system". I've regularly run all the system updates.
