[Bug 1967901] Re: Jammy fails to boot to live session in virt-manager with QXL

[Daniel van Vugt]

The gnome-shell crash is bug 1964458 so I'll remove references to that
here.

Your log shows Xorg is failing to start on QXL with:

avril 05 16:15:58 ubuntu /usr/libexec/gdm-x-session[4265]: (EE) Screen(s) found, but none have a usable configuration.
avril 05 16:15:58 ubuntu /usr/libexec/gdm-x-session[4265]: (EE)

avril 05 16:15:58 ubuntu /usr/libexec/gdm-x-session[4265]: (EE)

Although see also bug 1967719 and bug 1953035.
