UPDATE: As a control, I also performed a new online installation of Zorin OS 17.1 Core r2 on my laptop, with NVIDIA drivers and software updates enabled.
As with Ubuntu 22.04, this new installation defaulted to the Wayland session (instead of Xorg) with the NVIDIA 550.107.02 drivers installed, and the issue with launching libadwaita apps occurred again. As before, the Settings > About page only mentions the NVIDIA drivers in the "Graphics" field: https://i.imgur.com/6f2hR2K.png As a result, I can also confirm that the NVIDIA 550.107.02 drivers are also causing the system to default to the Wayland session instead of Xorg. This means any new online installation of Ubuntu 22.04 with NVIDIA would experience this bug by default. If you would like any more information from me when troubleshooting this issue, feel free to let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080282 Title: Wayland is chosen as the default for Nvidia on Jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/2080282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
