ubuntu-drivers-common (1:0.4.23) artful; urgency=medium
[ Alberto Milone ]
* gpu-manager.{c|py}:
- Disable persistence mode before powering down the dGPU.
If persistence mode is not disabled, gpu-manager will not be
able to unload the nvidia module.
- Add support for using custom xorg.confs with the nvidia
driver (LP: #1667198).
Custom xorg files can be named "non-hybrid" (for non hybrid
systems), "hybrid-performance", and "hybrid-power-saving",
and will have to placed in the /usr/share/gpu-manager.d
directory.
The directory can be overridden by passing another directory
along with the "--custom-xorg-conf-path" parameter.
- Add tests for the custom xorg.confs code and for amdgpu-pro
hybrid support.

* debian/control:
- Add build dependency on libkmod-dev.
* gpu-manager.c:
- Detect and handle switchable graphics with the amdgpu-pro driver.
AMDGPU-Pro has its own script to switch between powersaving and
performance mode.
Some machines allow enabling switchable graphics, or disabling
the iGPU completely, thus leaving only the dGPU on. This new code
simply detects the different profiles supported by AMD, and
enables powersaving mode when possible.

Title:
gpu-manager should also support reading kernel parameter to adding
options in xorg.conf for Nvidia
Status in OEM Priority Project:
Confirmed
Status in ubuntu-drivers-common package in Ubuntu:
Fix Released
Bug description:
This feature has been implemented for Intel (ex. gpumanager_uxa),
which is parsing kernel parameter to add option in xorg.conf (commit
ff3a4e54).
And now Nvidia also need this feature to add Option
"nvidiaXineramaInfo" "off" to fix some issues.
Btw, I'm thinking it might be a more flexible to have a config file
which user could add all options as they want so that we could prevent
keeping change gpu-manager when some more options are needed in the
future.
