Title:
DPMS does not work correctly on hybrid systems
Status in “xorg-server” package in Ubuntu:
Fix Released
Status in “xorg-server” source package in Raring:
New
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.
