SUMMARY On multiple clean installations of both Arch Linux and Kubuntu 24.04 (Plasma 6) on both wayland and X11, all apps launched under systemd appear with a corrupted service ID like: ´´´ app-org.kde.konsole@ffffffffffff4fffbfffffffffffffff.service ´´´ This results in errors like: ´´´ Unit app-org.kde.konsole@ffffffffffff4fffbfffffffffffffff.service was already loaded or has a fragment file. ´´´ Session ID or activity UUID is consistently stuck at: ´´´ ffffffff-ffff-4fff-bfff-ffffffffffff ´´´ This causes: All launched apps to share the same corrupted systemd unit Failure to open second windows Broken D-Bus integration Incomplete user session under loginctl STEPS TO REPRODUCE 1. Perform a clean install of Kubuntu 24.04 or Arch Linux with KDE/Plasma 2. Log in as a new user 3. Launch Konsole or any app 4. Running ´´´ qdbus6 org.kde.ActivityManager /ActivityManager/ListActivities ´´´ Returns ´´´ Error: org.freedesktop.DBus.Error.UnknownObject No such object path '/ActivityManager/ListActivities' ´´´ Attempting to manually start kactivitymanagerd via kquitapp6 or kactivitymanagerd --no-respawn does not fix it EXPECTED RESULT kactivitymanagerd should initialize a real UUID and register valid activities App unit names should reflect per-window UUIDs KDE session should be systemd-integrated without launching failures WHAT I TRIED: Wiped ~/.local/share/kactivitymanagerd, ~/.config/kactivitymanagerdrc, etc. Ran kactivitymanagerd manually Created new activities manually in System Settings Tried on both Wayland and X11 sessions Verified machine ID (/etc/machine-id) is valid BIOS UUID is valid (/sys/class/dmi/id/product_uuid) Confirmed uuidgen works Verified systemd --user session exists and is running SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.04 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.3 Kernel Version: 6.14.0-15-generic (64-bit) Graphics Platform: Wayland Processors: 16 × AMD 4700S 8-Core Processor Desktop Kit Memory: 15.6 GiB of RAM Graphics Processor: AMD Radeon RX 550 / 550 Series ADDITIONAL INFORMATION I made a post on the kde forums with more info: https://discuss.kde.org/t/launcher-fails-to-open-new-windows-of-already-open-apps/34551/5?u=galen
Activities are per-user, but on current git master, I can't reproduce this if I create a new user account on the same machine: $ qdbus-qt6 org.kde.ActivityManager /ActivityManager/Activities org.kde.ActivityManager.Activities.ListActivities ce4eee70-b7f3-43f8-8639-e734f2103ffa
I have the same issue using an AMD 4700S desktop kit cpu, which i assume you are using as well according to this: https://discuss.kde.org/t/launcher-fails-to-open-new-windows-of-already-open-apps/34551/7 I am using PikaOS with KDE
