---------------
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.

It's because ubiquity launches `ubuntu-drivers install --packages-list
...` in live system but install each package to target storage.
When installing nvidia-prime, the preinst set "on" to "/etc/prime-
discrete" which will be referred by gpu-manager. The gpu-manager will
set to performance mode.
After confirming with Alberto on Mattermost, since we don't have a
nvidia driver which lower than 450 version since focal.
I think we are ok to switch to on-demand mode.
