Title:
FFE: support for NVIDIA runtimepm (hybrid gfx)
Status in OEM Priority Project:
New
Status in ubuntu-drivers-common package in Ubuntu:
Triaged
Bug description:
The work that went into ubuntu-drivers-common and nvidia-prime is
meant to enable RTD3 support on Intel/NVIDIA or AMD/NVIDIA hybrid
systems, introduced by the NVIDIA 450 driver series.
This allows the supported systems to make use of the integrated GPU
(Intel or AMD) and to keep the discrete NVIDIA GPU powered down until
needed. While powered down, the NVIDIA GPU can still detect any
events, should external displays be plugged in.
This brings hybrid graphics on Linux on par with Windows.
Only the supported GPUs will be able to benefit from this change. This
is why NVIDIA provides a hardware database (included in the nvidia
packages), which gpu-manager can now parse. The ubuntu-drivers tool
relies on that detection to enable this new feature when installing
the NVIDIA driver.
Another improvement is the ability of ubuntu-drivers to detect LTSB
(Long term support branch), NFB (New feature branch), Legacy, Beta
flags, which the NVIDIA drivers can have, and make informed detection
choices.
This work also includes a number of bug fixes reported on errors.ubuntu.com.
Requirements:
The new ubuntu-drivers-common:
The new nvidia-prime:
