tails-gdm-failed-to-start.service gives confusing info on systems with 2+ GPUs
We see lots of reports flowing in (#16875 (closed), #17479 (closed)) that are not
actionable as-is because
about the integrated GPU (typically Intel), while in most cases the
discrete GPU (typically Nvidia or AMD) is used.
Ideally this service would be able to tell which GPU is used. Worst case, when there are multiple GPUs, perhaps it could display info about the non-Intel one, if any.
