I don't think this bug should only occur on VirtualBox. One reason we've focussed on VirtualBox might just be that ubuntu-restricted-* fails to install on other systems, which is a different bug.
Evidence suggesting non-virtual systems also have the bug: * Bug 1992285 * https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5710 * https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5956 ** Summary changed: - Screen freeze before the login screen on VirtualBox (if the third party software option was selected) + Screen freeze before the login screen (if the third party software option was selected) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1988488 Title: Screen freeze before the login screen (if the third party software option was selected) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1988488/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
