Created attachment 170492 [details] coredumpctl debug 5984 SUMMARY This is a regression in Plasma 6.1. Plasma 6.0 was working perfectly. I can reproduce all the times. Many components crash when attaching the laptop to a docking station with the lid closed. When I open the lid, the lock screen is shown for a few seconds, before the whole session crashes and SDDM is shown. The reason I add this bug to xdg-desktop-portal-kde is because in the list of crashes coredumpctl list (see at the end), this is the first process to crash, but feel free to move it to the right place. STEPS TO REPRODUCE 1. Boot laptop and start Plasma 6.1 Wayland session 2. Close lid (laptop goes to sleep) 3. Attach laptop to docking station (I'm using a Dell WD19TBS) OBSERVED RESULT Laptop does not automatically wake up. Pressing external keyboard does not wake up the laptop either. When opening the lid (with laptop still attached to docking station), laptop wakes up but opened session crashes. EXPECTED RESULT Laptop automatically wakes up and lock screen is shown in external monitor (as in Plasma 6.0) SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.90 KDE Frameworks Version: 6.3.0 Qt Version: 6.8.0 Kernel Version: 6.9.4-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 22 × Intel® Core™ Ultra 7 155H Memory: 30.9 GiB of RAM Graphics Processor: Mesa Intel® Arc Manufacturer: LENOVO Product Name: 21KDS00600 System Version: ThinkPad X1 Carbon Gen 12 This is the output of coredumpctl list: Fri 2024-06-14 08:18:27 CEST 5984 1000 1000 SIGABRT present /usr/lib/xdg-desktop-portal-kde 1M Fri 2024-06-14 08:18:27 CEST 4335 1000 1000 SIGSEGV present /usr/bin/konsole 3.2M Fri 2024-06-14 08:18:27 CEST 3435 1000 1000 SIGSEGV present /usr/bin/dolphin 4.9M Fri 2024-06-14 08:18:27 CEST 7037 1000 1000 SIGABRT present /usr/lib/xdg-desktop-portal-kde 1019.9K Fri 2024-06-14 08:18:27 CEST 7082 1000 1000 SIGABRT present /usr/lib/xdg-desktop-portal-kde 1017.9K Fri 2024-06-14 08:18:27 CEST 7115 1000 1000 SIGABRT present /usr/lib/drkonqi 863.4K Fri 2024-06-14 08:18:27 CEST 7097 1000 1000 SIGABRT present /usr/lib/xdg-desktop-portal-kde 1016.9K Fri 2024-06-14 08:18:27 CEST 7117 1000 1000 SIGABRT present /usr/lib/drkonqi 864K Fri 2024-06-14 08:18:28 CEST 7155 1000 1000 SIGABRT present /usr/lib/xdg-desktop-portal-kde 1016.4K I attach the trace of the first crash.

does kwin crash as well?
.
Sometimes KWin crashes, sometimes it doesn't. When it crashes the laptop freezes for a while (sometimes just the cursor is shown) and then the SDDM screen appears. Other times, lately more often (I don't know if it's related to having updated to the release of 6.1), the laptop is unresponsive for a while and then it just works. I got used to to open the laptop lid before attaching the laptop to the docking station, and this seems to always avoid the issue.
6.1.2 seems to have improve the situation a little bit, but still feels less reliable than 6.0. For example, last two times I attach the laptop to the docking station there was no complete crash (going to SDDM) but there was a period of time (~5-10 seconds) where the laptop was unresponsive in the locking screen. The only crashes I observed now were related to ddcutil: Mon 2024-07-08 09:17:48 CEST 9422 0 0 SIGSEGV present /usr/bin/ddcutil 119.3K Mon 2024-07-08 09:17:48 CEST 9421 0 0 SIGSEGV present /usr/bin/ddcutil 118.3K Mon 2024-07-08 09:17:49 CEST 9802 0 0 SIGSEGV present /usr/bin/ddcutil 117.8K Mon 2024-07-08 09:17:49 CEST 9804 0 0 SIGSEGV present /usr/bin/ddcutil 117.7K I have left a comment with the bt in this other bug report (I thought it was related when searching recent ddcutil related issues, but perhaps I'm wrong): https://bugs.kde.org/show_bug.cgi?id=489169#c19
These ddcutil crashes are different from that one, and also different from what this is reporting. Sounds like this issue is fixed now, and has been replaced with a new different ddcutil crash. Can you open a new bug report for that? Thanks!
