Bug Description


 * The progress bar that is drawn to keep track of the update-initramfs process can result, sometimes, in a BrokenPipe error. In no way does this affect the final result of the actual operation, yet it causes the progress bar to crash.

[Test Plan]

 * Install the nvidia-prime package and , and then execute "sudo prime-select intel" so that NVIDIA can be disabled, and the update-initramfs command is called. This might need repeating (i.e. going back and forth from "sudo prime-select intel" to "sudo prime-select on-demand" until the BrokenPipe error shows up.

[Where problems could occur]

 * This can cause no regression, since it does not alter the actual functioning on nvidia-prime, and the change has been in Impish since its release.

nvidia-prime (0.8.16~ focal; 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).
    - Don't check the current profile when setting
      a profile (LP: #1946476).
    - Handle BrokenPipeError (LP: #1965520).
