Bug Description
The work that went into ubuntu-
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.
