---------------
nvidia-prime (0.8.17) impish; urgency=medium
[ Jeremy Szu ]
* Set on-demand mode as default nvidia mode (LP: #1942307)
[ Alberto Milone ]
* prime-select:
- Detect chassis type and enable RTD3 only
on laptops (LP: #1942788).
- on-demand mode doesn't need to depend on
RTD3 (LP: #1942789).
- Use bootvga detection when last_gfx_boot
is not available.

Title:
On-demand and RTD3 need to be separated
Status in OEM Priority Project:
Confirmed
Status in nvidia-prime package in Ubuntu:
Fix Released
Status in ubuntu-drivers-common package in Ubuntu:
In Progress
Bug description:
RTD3 is a nvidia GPU feature to support runtime suspend.
On-demand would be a X offloading feature.
They are independent, according to discussion on
https://github.com/tseliot/ubuntu-drivers-common/issues/55.
Some parts need to be adjusted, e.g.
```
# If we are dealing with NVIDIA PRIME, and runtimepm
# is supported, enable it
if (os.path.isfile('/run/nvidia_runtimepm_supported') and
os.path.isfile('/usr/bin/prime-select')):
print('Trying to select the on-demand PRIME profile')
try:
subprocess.call(['prime-select', 'on-demand'])
except:
pass
# Create the override file for gpu-manager
with open('/etc/u-d-c-nvidia-runtimepm-override', 'w') as f:
f.write('# File created by ubuntu-drivers\n')
```
