--- Comment #1 from Guillaume Castagnino <casta+...@xwing.info> --- I can report the same crash here with kf 5.102 and plasma 5.26.90. The crash did not occur with plasma 5.26.5 Only one monitor connected using DP, the crash can be triggered simply by powering off/on the monitor. It seems to crash when powering back on the screen. I did not manage to get a stacktrace yet. Nothing special in log files when powering on the screen as you can see: janv. 29 11:11:26 dagobah kded5[836]: colord: Setting X atom (id: 0 ) "_ICC_PROFILE" on output: "DP-1" janv. 29 11:11:26 dagobah dbus-daemon[539]: [session uid=1000 pid=539] Activating via systemd: service name='org.kde.kscreen.osdService' unit='plasma-kscreen-osd.service' requested by ':1.12' (uid=1000 pid=836 comm="/usr/bin/kded5") janv. 29 11:11:26 dagobah systemd[504]: Starting plasma-kscreen-osd.service... janv. 29 11:11:26 dagobah dbus-daemon[539]: [session uid=1000 pid=539] Successfully activated service 'org.kde.kscreen.osdService' janv. 29 11:11:26 dagobah systemd[504]: Started plasma-kscreen-osd.service. janv. 29 11:11:27 dagobah kscreen_backend_launcher[1037]: kscreen.xrandr: Emitting configChanged() janv. 29 11:11:27 dagobah kded5[836]: KCrash: Attempting to start /usr/bin/kded5 janv. 29 11:11:27 dagobah kded5[836]: KCrash: crashing... crashRecursionCounter = 2 janv. 29 11:11:27 dagobah kded5[836]: KCrash: Application Name = kded5 path = /usr/bin pid = 836 janv. 29 11:11:27 dagobah kded5[836]: KCrash: Arguments: /usr/bin/kded5 janv. 29 11:11:27 dagobah ksmserver[1330]: 11:11:27.832 WARN unknown env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP janv. 29 11:11:27 dagobah keepassxc[1023]: kf.notifications: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP janv. 29 11:11:27 dagobah fookb[1154]: kf.notifications: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP janv. 29 11:11:27 dagobah systemd[504]: plasma-kded.service: Main process exited, code=dumped, status=11/SEGV janv. 29 11:11:27 dagobah systemd[504]: plasma-kded.service: Failed with result 'core-dump'. janv. 29 11:11:36 dagobah plasmashell[898]: trying to show an empty dialog -- You are receiving this mail because: You are watching all bug changes.
