--- Comment #7 from bin.w...@mail.binwang.me --- There is nothing in coredumpctl. I tried to kill all the powerdevil process and use gdb to run it. This time the crash icon doesn't appear in the system tray anymore. Even the process eventually crashes. I attached the back trace for the crash. I noticed something in my log: powerdevil has been failing for at least more than one month before I upgraded KDE to 5.27.0. But since there was no crash icon flashing in the system tray, the system were usable. Since I'm using a desktop, I'm not sure if powerdevil failure affects me. I haven't checked the power management in system settings for a long time so I'm not sure if that was broken as well. But I remember I've set my system not to black screen or lock when I'm not using it, which was a long time ago. -- You are receiving this mail because: You are watching all bug changes.
