The failure message appears on every reboot, each time with a different file of the form /var/lib/gdm3/.config/mutter/sessions/<some arabic digits>.ms .

Absent session files in absent directories shouldn't get opened.  Any bugfix?  Any remedy?

Gratefully,

The directory /var/lib/gdm3/.config/mutter/sessions doesn't even exist.

A more urging error than the above warning message is that Wayland
doesn't start (instead, X11 starts). I have no idea how little or how
much this warning contributes to the overall Wayland failure (as my log
shows dozens of warnings and errors, each of them might contribute, at
least hypothetically).

If this isn't implicated in any user-visible problem, then it's almost
certainly harmless, and definitely not Severity: important.

The gdm display manager runs gnome-shell in a special mode to provide
its "greeter" (login prompt) user interface, but there isn't really
any state in that session that would be useful to save, so the fact that
gdm can't load a saved state is not doing anyone any harm.

Arguably the fact that it tries to load a saved session file and logs a
message while in this special mode is a minor bug, but gnome-shell is a
large, user-facing component with many more users than developers, and
as a result, a very large number of bug reports that are more serious
than this one.

If this offends you, then you could do the research into why this is
appearing and send a merge request upstream to silence it; but please
bear in mind that even if you take the time to do that, the time needed
for a developer to review whether that contribution is correct would be
time that they cannot spend on something with a higher impact, like for
example diagnosing and fixing a crash.

This is unlikely to be fixed as a Debian-specific change. Any change has a
risk of causing regressions, so we have to weigh up that risk against the
benefit of fixing a bug. If the bug is minor, then the maximum possible
benefit is very small, so any risk at all would be a problem.

Simon, thanks for the extensive reply.

The main user-visible problem on my computer these days is that X11 is used instead of Wayland, and the only big action of mine was upgrading to Debian 12 from Debian 11 (with a few packages from Debian 12). Before we get to the first Wayland-related message in the log in some yet-to-be-written bug report, we better deal with all the visible warnings, errors, and failures, one by one, that happen earlier because an issue happening at time 𝑡 may potentially be (and sometimes is) a consequence of failures happening at times < 𝑡. Dealing with issues one by one, starting with the earliest, is usually the technically most _proper_ way to deal with software. (Ideally, we'd better start even with the high-level architecture of the GUI, but it's too far from the specific topic here.)

If my memory serves me right, at least the state of the Num Lock was saved in certain older Debian versions. I'm going to double check on this.

A crash is sometimes (of course, not always) a consequence of an accumulation of issues which happened earlier. (What I personally learned by looking into the documentation of failures of safety-critical or security-critical applications is that for such applications, a hard failure can _always_, to the extent of my knowledge, be contributed to a combination of issues, and that these hidden issues are very difficult to figure out only from the user-visible symptoms; sometimes the root causes are never found.)

What you said, essentially, means that resources (here, time) might lack to develop a system the proper way. I fully and completely understand; no argument here. At the same time, this lack of resources is more an organizational problem and less a technical one. (The question of how to organize software development, in particular open-source software development, in such a way that the technically ideal path will be followed with little resources available is both extremely important and difficult. In my view, the sheer multitude of > 80K bugs on www.debian.org/Bugs is not only due to the size of Debian but also a result of the inability to find and follow the technically ideal path. This is not specific to Debian; other software projects suffer similarly. In short, the situation is already bad, and it will get only worse if the current method of software development continues. I'm not going to discuss this question here further, as this would lead us too far away from the topic.)

Practically and pragmatically, given the fact that some folks develop a piece of software (here: Gnome) mainly because this is what they want to do (and not only because they have to do it, e.g., to get paid), I hope that I'm providing these folks with feedback. Given that I'm dealing with tons of issues myself, I'm probably doing already more than the majority of Gnome users. It's impossible for me to do more now (otherwise I simply run out of time, sleep, health, and money); even reporting all the red-colored failures in the journal is highly likely to be out of my reach. I hope that if at any point a developer decides to look into any particular issue or a combination of issues, he/she gets the logs he/she needs. In this case, the corresponding bug report(s) will be of help. I apologize if my bug reports sound too harsh (I guess, I have felt simply overwhelmed and extremely helpless; I promise to express myself more professionally).

I get it. At the same time, in my understanding, this is what Debian *experimental* and then Debian *sid* are made for. If eventually a fix is available (say, from the original authors upstream), I don't see any reason for you to reject it, even if it lands only in, e.g., Debian 12.5 or in Debian 13. After all, you really don't wish to say that you wouldn't welcome it if the session-saving-and-restoring functionality gets either fixed or removed. (If, for whatever reason, a piece of software can't be fixed, it must be removed, because running useless/faulty pieces of software is both a risk and a waste by itself. E.g., counting the contribution of the bugs worldwide to the exhaust of the carbon dioxide into the atmosphere is a sobering exercise. Again, let me not go off the topic here.) An aside: the situation might – purely hypothetically, of course – turn out to be even worse, namely if the offending message “Window manager warning: Failed to parse saved session file: …” does _not_ reflect what really happens, thus leading us all astray. Having said this, could I kindly ask you whether it is possible for you to at least remove the wonfix tag and perhaps raise the severity again, for example, to normal?

Gratefully,
AlMa
