** Description changed: I've identified a regression with the latest update to the NVIDIA 550 drivers in Ubuntu 22.04. This prevents any libadwaita apps from launching while using the Wayland display server. It appears that the latest available NVIDIA 550.107.02 package pulls in some new dependencies, such as libnvidia-egl-wayland1 and some other i386 support packages (libnvidia-egl-wayland1:i386 libwayland- client0:i386 libffi8:i386). They seem to enable Wayland support out of the box, which sets Wayland as the default desktop for new installations of Ubuntu 22.04 (assuming software updates are enabled from the Ubuntu installer). However, any attempt to launch libadwaita apps from within Wayland with the NVIDIA 550.107.02 drivers installed always fails. When launching any of these libadwaita apps from the Terminal, it always returns one of the following three errors: - Gdk-Message: Error 71 (Protocol error) dispatching to Wayland display. - Gdk-Message: Error reading events from display: Protocol error - Gdk-Message: Error flushing display: Protocol error Some of the affected apps include gnome-text-editor, gnome-sound-recorder, and gnome-shell-extension-manager which are available from the standard Ubuntu repositories. - When I researched these error messages, I found that other Linux distros - also seem to be experiencing this bug, including Fedora: - https://discussion.fedoraproject.org/t/gdk-message-error-71-protocol- - error-dispatching-to-wayland-display/127927/6 + When I researched these error messages, I found that other Linux distros also seem to be experiencing this bug, including Fedora: https://discussion.fedoraproject.org/t/gdk-message-error-71-protocol-error-dispatching-to-wayland-display/127927/6 + However, the "GSK_RENDERER=gl" solution in bhundven's post in that thread didn't work in Ubuntu 22.04 when I tested it. For reference, I was able to replicate this issue on an ASUS Zenbook UX303LB with an NVIDIA 940M graphics card running the newest available NVIDIA 550.107.02 driver on a fresh installation of Ubuntu 22.04.4 with all of the latest software updates installed. However, downgrading to an older version of the NVIDIA drivers (like version 535) without full Wayland support makes this error disappear, with either Xorg and Wayland selected from the login screen. In our testing, Ubuntu 24.04 doesn't seem to be affected by this issue in Wayland or Xorg. However, we also noticed that Ubuntu 24.04 still defaults to Xorg on NVIDIA 550.107.02, even with the latest updates downloaded by the Ubuntu installer (unlike Ubuntu 22.04). I'm aware that your team is preparing to launch Ubuntu 22.04.5 on 12 September. However, as this is an out-of-the-box bug with the default version of the NVIDIA drivers for most NVIDIA users, it may be worth investigating this issue to avoid new users having a bad experience. Perhaps it might be worth sticking with Xorg by default in Ubuntu 22.04 installations with the NVIDIA 550 drivers as a workaround? If you need any help or additional information when trying to replicate or investigate this issue, please let me know and I would be happy to help.
