I can't see anything going wrong in those files, although it doesn't help that we don't have a fresh journal from when gnome-shell was last attempted instead of Sway. It's understandable you'd choose whatever works.
Since you say it was working a couple of weeks ago: > EXPECTED BEHAVIOR: > gnome-shell/mutter successfully opens /dev/dri/card1 via GBM and starts > normally, as it did on this same > machine/package-set combination as recently as 2026-07-06 (last > confirmed-working boot log shows "Added device > '/dev/dri/card1' (i915) using atomic mode setting." / "Created gbm renderer"). then I can only imagine some update or personal change has broken it. Looking at the updates you have, I can only see kernel updates as possible suspects. Perhaps the simplest way to rule things in or out would be to boot the Ubuntu 26.04 ISO from USB again. Make sure that's still working. If it is then I can only think to reinstall Ubuntu from scratch and see if the bug reoccurs after the official updates are applied. Otherwise it seems more likely some personal change broke the system (like trying PPAs). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2160652 Title: gnome-shell/mutter 50.1 fails to start on Intel Alder Lake iGPU: gbm_create_device() returns EINVAL ("Failed to open gpu ...
