[Bug 2085404] Re: No display after booting

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.
