Bug Description

[Impact]
 * When using nvidia drivers in the prime configuration listed in their README will not turn off correctly on DPMS.
 * External displays driven from the non-primary graphics card will not turn off either.

[Test Case]
 * Get an affected system configuration, either with the binary drivers or open source drivers.
 * Run 'xset dpms force off'.
 * Backlight and external displays should turn off.

[Regression Potential]
 * Unlikely, the patch is from upstream. Any regressions would only happen on hybrid systems, and the dpms on/off code is already tested in all drivers in non-hybrid configurations. The most likely regressions would involve backlight somehow.

[Other Info]
 * Commit 6238bd68bd71323f8b4f1808f34dabe2ae447fe3 upstream.
 * Patch is included in the x1.14 release.

Hello Maarten, or anyone else affected,

Accepted xorg-server into raring-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/xorg-server/2:1.13.3-0ubuntu6.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Removing verification-failed, this bug seems to be from someone who doesn't respond, and uses an unsupported configuration. He didn't restart xorg-server after upgrading, which is not really helpful for diagnostics.
