Created attachment 178809 [details] journalctl Short description: I was working, locked the session to go to lunch, came back and found the session frozen :O Sometimes this problem occurs on resume from standby if the laptop goes into standby attached to the docking station (at home) and wakes up unplugged or attached to a different docking station (at the office) with different screens, but in this specific case I did not do this. Hardware: Lenovo T14 2° gen. i5-1135G7 with 48GB DDR and 4k screen (#1) Docking DELL WD19TB (usbc/thunderbolt) LG 27GR93U UltraGear (displayPort) (#2) LG 27UL650 (displayPort) (#3) all screens have 4k resolution Versions: Fedora 40 Linux T14d.localdomain 6.12.11-100.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Jan 23 22:07:15 UTC 2025 x86_64 GNU/Linux kwin-wayland-6.3.0-3.fc40.x86_64 kde-settings-40.1-1.fc40.noarch plasma-desktop-6.3.0-1.fc40.x86_64 systemd-255.16-1.fc40.x86_64 mesa-libGL-24.1.7-1.fc40.x86_64 xorg-x11-server-Xorg-1.20.14-36.fc40.x86_64 xorg-x11-drv-intel-2.99.917-57.20210115.fc40.x86_64 Enviroment: - laptop connected directly to the docking station with its thunderbolt cable - 2 wayland sessions with different users: user(uid:1006) and user1(uid:1000), the problem was with 'user' (uid:1006) which was the active session - many windows opened (firefox, code, dbeaver, zoom, konsole, ...) Behavior: 1. I locked the screen, I turn off the external monitors and I gone away 2. I come back after, the laptop screen was turned off(energy saving) 3. I moved the mouse (touchpad) and the laptop screen turned on 4. I turned on the external screen (#2) and (#3) Issue: 5. the screen (#2) was turned on but black, the laptop and screen (#3) had the background with the session locked, no action made the login prompt appear to unlock the session (moving mouse, typing keys, change session with CTRL+ALT+F7 and then again CTRL-ALT-F8, ...) I tried from the other session to unlock the other session with 'loginctl unlock-sessions' but nothing in the end, i had to 'loginctl kill-session 19'
