Bug Description

From time to time, GNOME session gets reset when usb-c cable from docking station gets disconnected. All applications gets closed and completely new, fresh GNOME session is created.
This is not happening every single time, when the cable gets disconnected but in about 1/3 of cases.

As I remember it's happening only when laptop is suspended or have screen locked. When the laptop is working, and screen isn't locked, it's not happening (I could be wrong but this is my observation).

The bug is highly unpleasant because it's closing every single app on the computer, and every single process running in the current session.
I'm almost sure it was happening for several last kernels, this is not a new issue, I had this problem for a long time (at least for 6 months).

Attachment (20211018_210936.jpg) is related to it, it's the info I see on the screen when the bug occurs.

Short info:
Laptop: Thinkpad E14 Gen2 AMD, Ryzen 5 4500u,
Sysytem: Ubuntu 21.10, GNOME 40.4.0, X11, kernel 5.13.0-39-generic,
Docking station: Thinkpad USB-C Dock Gen2, 40AS, 20/06, 0090EU

Another case, but this time positive: laptop was suspended, docking station has been disconnected, and after waking up (which took some time, about 8s) everything was fine.

But, yesterday I've installed "displaylink-driver-5.5.0-59.151.run" and I don't know if this changed the situation or nor. I don't have another "positive case" logs prior to installation of displaylink-driver.

POSITIVE CASE:

Could you add a 'journalctl -b 0 > log' to the bug after getting the issue?

@seb128, sure, attachment "log.txt" (journalctl -b 0) contains what you request, and it was taken just after the issue. More or less, at ~17:05 I detached docking station, and after this I logged in and fresh GNOME session appeared to my eyes. Immediately after logging in I gathered the log.txt.

Another logs, this time the message I see during startup, for a very short time. It takes place when laptop is attached to docking station.
I think it is related to the issue.

(there could be some typo due to wrong OCR or just normal typo; photo of the log attached)

This is getting worse with time. Right now I can't detach docking station when session is locked (not suspended, but locked). And after detaching computer from docking station I see one color screen, no controls, no unlock, no login, nothing, and the only thing I can do is to restart computer or switch to terminal and restart session.

I'm not even pasting logs, because the issue seems to be dead anyway.
