The only crash-like problem I can see in those logs is:
simple-framebuffer simple-framebuffer.0: drm_WARN_ON(map->is_iomem)
which seems to be non-fatal for the Xorg process that triggered it. The
cause of that issue is also bug 2060268, but that too is not a crash. So
please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
GDM session crashes after returning from a screen-off.
Status in Ubuntu:
Incomplete
Bug description:
I've written an AskUbuntu question about this:
https://askubuntu.com/questions/1511958/screen-lock-keeps-occuring-
on-24-04-even-though-i-believe-ive-disabled-it/1512075#1512075
Originally I thought it was gnome not respecting my setting to prevent
locking the screen after idling, but after discussing the issue on
matrix (https://matrix.to/#/!EJhpCQHHqqcNicfiql:xentonix.net/$kPbn-
fqDZgoG4s6PyQfki8tcSKJUpGH9QrXZSSV_vKY?via=decred.org&via=matrix.org&via=ubuntu.com)
I think it is actually just a gdm or gnome-shell crash that happens
when the PC idles, the screen turns off, and then I wake it.
To summarize the symptom. I have the PC set to disable the screen
after being idle for 5 minutes. I also set it such that it should not
lock the session when this happens. (I want to turn on the screen and
get right back to where I was without password overhead). What I've
observed is that when I give the idle PC keyboard input, it wakes to a
login screen, and when I login my windows from the previous session
are completely gone (although tmux sessions are still alive).
I've attached a relevant section of `journalctl --user` from around
the time when I last tried to interact with the idle PC. I believe the
"wake" event happens at `Apr 28 13:42:43` at which point we start
seeing whoopsie messages:
```
Apr 28 13:42:44 toothbrush systemd[1]: Started whoopsie.service - crash
report submission.
```
And then what looks like logs indicating that I was logged out and the
previous session was ended:
```
Apr 28 13:42:56 toothbrush systemd[1]: run-user-1000-gvfs.mount: Deactivated
successfully.
Apr 28 13:42:57 toothbrush gdm-password][60731]:
pam_unix(gdm-password:session): session closed for user joncrall
Apr 28 13:42:57 toothbrush systemd[1]: session-61.scope: Deactivated
successfully.
Apr 28 13:42:57 toothbrush systemd[1]: session-61.scope: Consumed 12min
9.467s CPU time.
Apr 28 13:42:57 toothbrush systemd-logind[1790]: Session 61 logged out.
Waiting for processes to exit.
Apr 28 13:42:57 toothbrush systemd-logind[1790]: Removed session 61.
```
The time from `13:42:44` to `13:43:07` where I get:
```
Apr 28 13:43:07 toothbrush systemd-logind[1790]: New session 221 of user
joncrall.
Apr 28 13:43:07 toothbrush systemd[1]: Started session-221.scope - Session
221 of User joncrall.
```
seems about right, because it takes a few seconds to go from de-idling
the machine to seeing any sort of display.
