[Bug 1959362] Re: "Launch using dedicated graphics card" option absent (nvidia, proprietary drivers, on-demand PRIME mode)

[jeremyszu]

yes, FWIK, we incline to provide the LTS branch (stable) for Ubuntu users.
For some cutting edge graphic cards, which will use 495 (since 470 doesn't support) and the 495 will eventually upgrade to next LTS version (FWIK, 510) in the future.

The installation logic is implemented in ubuntu-drivers-common.

Title:
  "Launch using dedicated graphics card" option absent (nvidia,
  proprietary drivers, on-demand PRIME mode)

Status in OEM Priority Project:
  Invalid
Status in gnome-shell package in Ubuntu:
  Invalid
Status in ubiquity package in Ubuntu:
  New

Bug description:
  Device: Dell Precision 5500 with discrete nvidia Quadro T1000 Mobile GPU
  Image: Jammy daily (20220126 build)

  Test steps
  ==========

  Secure Boot enabled

  Installation options:

  - used ubiquity (not the new flutter installer)
  - normal installation
  - checked "Install third-party software for graphics and Wi-Fi hardware and additional media formats"
  - left "Configure Secure Boot" checked
  - Setup a password for Secure Boot MOK enrollment
  - Used "Erase disk and install Ubuntu" option

  After installation completes, the device reboots and I enroll the MOK
  in the UEFI BIOS.

  At first boot, the default GNOME session is "Ubuntu" (not "Ubuntu on
  Wayland"), which seems to be expected given that I am using NVidia
  proprietary drivers.

  Once logged in, nvidia-settings and GNOME Settings About screen both
  show that the GPU is available. It is set in "On-Demand" in nvidia-
  settings.

  $ switcherooctl

  --------------------

  Expected result
  ===============

  When right-clicking on an icon in the launcher (for instance Firefox
  or Files), a "Launch using dedicated graphics card" option is
  available and launches the selected software using Nvidia GPU.

  Actual result
  =============

  However, there is no "Launch using dedicated graphics card" option
  available when right-clicking on an application launcher on the left.
