Comment 41 for bug 82312

I am still affected by this bug in Jaunty.

Why is this bug not fixed yet. It would be so easy for the ubuntu package to add the "UseDisplayDevice" "DFP" to the xorg.conf file for all laptops

This is not an upstream driver bug, from the README, appendix B (http://us.download.nvidia.com/XFree86/Linux-x86_64/180.51/README/appendix-b.html), the documentation says under the option UseDisplayDevice:

<quote>
Of the list of display devices considered for this X screen (either all connected display devices, or a subset limited by the "UseDisplayDevice" option), the NVIDIA X driver first looks at CRTs, then at DFPs, and finally at TVs. For example, if both a CRT and a DFP are connected, by default the X driver would assign the CRT to this X screen. However, by specifying:

    Option "UseDisplayDevice" "DFP"

the X screen would use the DFP instead.
</quote>

So it is well documented that all laptops which has a VGA connector must specify Option "UseDisplayDevice" "DFP" to ensure the driver would assign the DFP to the X screen.

And it is also very clear from the Xorg.0.log that this is the way the driver behaves. Take a look at this diff of Xorg.0.log_black and Xorg.0.log_DFP
