SUMMARY It's a bug that happened before but I am not sure why, I clicked on the dolphin file manager and screen went black for any monitors, only fix was hard reboot through button. Very rare and random. STEPS TO REPRODUCE 1. Click on Dolphin to open OBSERVED RESULT The desktop was still working, as I was able to close a browser that was playing a song with alt+f4, but that is the only thing I was able to do before the restart. EXPECTED RESULT Work as expected. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.5.5 KDE Frameworks Version: 6.22.0 Qt Version: 6.10.2 ADDITIONAL INFORMATION Not sure these contain the cause of the issue. It was after the reboot. https://pastebin.com/45cCCpss
❯ dolphin --version dolphin 25.12.2 QThreadStorage: entry 3 destroyed before end of thread 0x561189893bf0 QThreadStorage: entry 2 destroyed before end of thread 0x561189893bf0 It's in a arch linux based distro.
I've now setup journalctl properly, if happens again, it should have the previous boot log.
Thanks for the bug report and the detailed logs. It sounds like kwin crashed or ran into an error condition. From what I see, there may be a system level issue. It looks like a number of services may be misconfigured. These parts of the log are what leads me to think that: fev 06 12:44:58 desktop-pc dbus-broker-launch[3017]: Service file '/usr/share/dbus-1/services/org.kde.dolphin.FileManager1.service' is not named after the D-Bus name 'org.freedesktop.FileManager1'. fev 06 12:44:58 desktop-pc dbus-broker-launch[3017]: Service file '/usr/share/dbus-1/services/org.kde.kscreen.service' is not named after the D-Bus name 'org.kde.KScreen'. fev 06 12:44:58 desktop-pc dbus-broker-launch[3017]: Service file '/usr/share/dbus-1/services/org.kde.plasma.Notifications.service' is not named after the D-Bus name 'org.freedesktop.Notifications'. fev 06 12:44:59 desktop-pc wireplumber[3040]: default: Failed to get percentage from UPower: org.freedesktop.DBus.Error.NameHasNoOwner fev 06 12:44:59 desktop-pc wireplumber[3040]: spa.bluez5: BlueZ system service is not available fev 06 12:45:00 desktop-pc dbus-broker-launch[2558]: Activation request for 'org.freedesktop.Avahi' failed: The systemd unit 'dbus-org.freedesktop.Avahi.service' could not be found fev 06 12:45:05 desktop-pc pipewire[3671]: pw.conf: 0x561d1ba3ac40: error loading config '/home/user/.config/pipewire/pipewire.conf.d/20-echo-cancel.conf': Invalid argument fev 06 12:45:05 desktop-pc wireplumber[3674]: wp-conf: <WpConf:0x55e158c923e0> failed to open '/home/user/.config/wireplumber/wireplumber.conf.d/54-set-default-output-profile.conf': section 'monitor.alsa.rules' has no value fev 06 12:45:06 desktop-pc wireplumber[3674]: default: Failed to get percentage from UPower: org.freedesktop.DBus.Error.NameHasNoOwner fev 06 12:45:06 desktop-pc wireplumber[3674]: spa.bluez5: BlueZ system service is not available fev 06 12:45:06 desktop-pc kernel: nvme nvme0: using unchecked data buffer fev 06 12:45:06 desktop-pc kded6[3734]: QDBusObjectPath: invalid path "/modules/oom-notifier" fev 06 12:45:06 desktop-pc kded6[3734]: The kded module name "oom-notifier" is invalid! fev 06 12:45:06 desktop-pc kded6[3734]: QDBusObjectPath: invalid path "/modules/plasma-session-shortcuts" fev 06 12:45:06 desktop-pc kded6[3734]: The kded module name "plasma-session-shortcuts" is invalid! fev 06 12:45:06 desktop-pc kded6[3734]: Failed to connect to Bolt manager DBus interface: fev 06 12:45:06 desktop-pc kded6[3734]: QDBusObjectPath: invalid path "/modules/wpad-detector" fev 06 12:45:06 desktop-pc kded6[3734]: The kded module name "wpad-detector" is invalid! fev 06 12:45:06 desktop-pc kconf_update[3865]: /usr/share/kconf_update/filepicker.upd defined Version=5 but Version=6 was expected fev 06 12:45:06 desktop-pc kded6[3734]: QDBusConnection: name 'org.freedesktop.UPower' had owner '' but we thought it was ':1.53' fev 06 12:45:06 desktop-pc dbus-broker-launch[2558]: Activation request for 'org.freedesktop.ModemManager1' failed: The systemd unit 'dbus-org.freedesktop.ModemManager1.service' could not be found. fev 06 12:45:06 desktop-pc kded6[3734]: Failed enumerating MM objects: "org.freedesktop.DBus.Error.NameHasNoOwner" "Could not activate remote peer 'org.freedesktop.ModemManager1': activation request failed: unknown unit" You didn't mention which distro you have installed, but I recommend reaching out to their support channels to get your system in a good state first. If you continue to have problems after that, take a look at the Crashed Process Viewer and see if there are entries for kwin. If so we would need a backtrace of the crash. Thanks!
This one is CachyOS - https://github.com/CachyOS/distribution/issues/335
I also enabled / configured the coredump in case it helps.
I fixed many other things and reduced the logs to https://pastebin.com/hv6wdynn
I'm not sure if it's related to nvidia or not. But will share the only things that could make some sense in wayland. /etc/environment https://pastebin.com/raw/qCFW3BwA
