Looking at what appears in the log (/var/log/messages) the time when X freezes corresponds very well with when those messages are recorded. The question is, how do I usefully debug this? I've gone over the README's procedure a few times now and it unfortunately does not produce any coredumps or traces. One option is of course to trade up or sideways to something like https://www.power.no/data-og-tilbehoer/pc-og-mac/baerbar-pc/asus-zenbook-s-ux393ea-pure2-13-laptop/p-1115705/ (Intel Core i7-1165G7 with Iris Xe graphics), but would that have a better chance of success (or for that matter be helpful to the project)?
