DPMS does not work correctly on hybrid systems

Bug #1184999 reported by Maarten Lankhorst on 2013-05-28

Affects Status Importance Assigned to Milestone
xorg-server (Ubuntu)

Bug Description

 * 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.

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.
