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

 

You have been subscribed to a public bug:

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.

** Affects: xorg (Ubuntu)
     Importance: Undecided
         Status: Incomplete
