@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.
** Attachment added: "log, journalctl -b 0" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1967613/+attachment/5576926/+files/log.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1967613 Title: Gnome session reset after docking station disconnects Status in linux package in Ubuntu: Confirmed 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 Logs:
