Bug ID: 479029 Summary: Improper behavior on shutdown leading to data loss Classification: I don't know Product: kde Version: unspecified Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: descartav...@gmail.com Target Milestone: --- Created attachment 164449 --> https://bugs.kde.org/attachment.cgi?id=164449&action=edit sudo journalctl -b -1 SUMMARY Improper shutdown of everything under the kwin shell. I suspect this is a combination of moving to incomplete features on systemd, wayland and QTdBus. STEPS TO REPRODUCE 1. Start KDE 2. Open terminal or other applications that can spawn other processes 2.1 start application that saves a PID file and remove them on exit, e.g. `qemu` 3. Open "regular" kde applications 3.1 pay attention to things that are only save on application exit, e.g. ktorrent magnet list 4. click shutdown OBSERVED RESULT System shutdowns extremely fast. PID files from terminal applications are still laying around. Data from KDE applications are lost: e.g. https://bugs.kde.org/show_bug.cgi?id=425898 EXPECTED RESULT System sends and wait for applications to exit SOFTWARE/OS VERSIONS Linux: 6.6.8-arch1-1 (64-bit)
