[Bug 1962523] Re: [Wayland][Nvidia] gdm default use Xorg in 22.04 if proprietary nvidia installed

[Jeremy Bicha]

Yes, Menno, this is a regression in that Ubuntu 21.10 enabled Wayland
for Nvidia and Ubuntu 22.04 now does not.

An issue was identified with suspend not working for GNOME requirements.
Once the Nvidia drivers are updated to fix that issue in a future stable
release update, Wayland should be available again.

Title:
  [Wayland][Nvidia] gdm default use Xorg in 22.04 if proprietary nvidia
  installed

Status in OEM Priority Project:
  Fix Released
Status in gdm3 package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

   * In Ubuntu 22.04, gdm should use Wayland by default even if proprietary nVidia driver is in use.
   * gdm upstream prefers Wayland if nvidia version newer than (or equal) to 510. It same as Ubuntu's strategy[1]. 

  [Test Plan]

  Steps:
  1. Download jammy daily build
  2. Install nvidia driver by selecting "install third-party packages.." during the installation.
  3. Login without selecting modes (e.g. "Ubuntu" or "Ubuntu on Wayland" or enable auto-login during the installation.

  [Where problems could occur]
   * If nVidia GPU doesn't support Wayland then it will be a problem but it doesn't means this patch leads a regression, instead, the problem should always there as it is if the user switches to Wayland mode no matter default mode.
   * This ticket switches the default mode to Wayland. If there is a problem then user will encounter it after the installation which has bad experience.
   * However, it's not regression because Jammy is a new LTS version and we decide to switch to Wayland. If a problem occurs, then we fix it.
