The EDID issue is possibly unrelated. gnome-shell gets SIGKILL'd if its realtime thread uses too much CPU during startup. This may be mutter's fault like in bug 2077216, or it may be due to an i915 bug alluded to above.
First we would like to know if the fix for bug 2077216 helps, so please try 24.10 if you can. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2085404 Title: No display after booting Status in linux package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: [Impact] No display is shown after booting the machine.
