Is this crash reproducible in Plasma 6? I haven't tried Plasma 6 yet but I will and report back. Additional information: I made a wrong assumption about my KVM switch. With the switch set to computer B, I thought the screen would appear disconnected on computer A, but it doesn't. kscreen-doctor --outputs still shows Output: 5 HDMI-A-1 enabled connected priority 1 HDMI Modes: 0:1920x1080@60*! 1:1920x1080@60 2:1920x1080@60 3:1920x1080@50 4:1680x1050@60 5:1600x900@60 6:1280x1024@60 7:1440x900@60 8:1280x800@60 9:1280x720@60 10:1280x720@60 11:1280x720@60 12:1280x720@50 13:1280x720@50 14:1024x768@70 15:1024x768@60 16:800x600@72 17:800x600@60 18:800x600@56 19:720x576@50 20:720x576@50 21:720x480@60 22:720x480@60 23:720x480@60 24:720x480@60 25:640x480@73 26:640x480@67 27:640x480@60 28:640x480@60 29:720x400@70 30:1280x1024@60 31:1024x768@60 32:1280x800@60 33:1920x1080@60 34:1600x900@60 35:1368x768@60 36:1280x720@60 Geometry: 0,0 1920x1080 Scale: 1 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: unknown As opposed to physically yanking the HDMI cable from the switch: in that case kscreen-doctor --outputs shows nothing. The issue seems to occur only when connected to the KVM switch. (In reply to Vlad Zahorodnii from comment #1) > Is this crash reproducible in Plasma 6? Using the KDE Neon unstable ISO, I can't reproduce the issue. I noticed the crash seems to only occur when ktimetracker is active, even though I can't find anything relevant in the logs. |
SUMMARY On a desktop with a single monitor attached, when the HDMI cable is disconnected (or, in my case, the kvm switch switched to the other computer) and later reconnected, kwin_wayland crashes. STEPS TO REPRODUCE 1. Unplug, or hit the KVM switch, while a session is active. 2. After a little while (presumably long enough for an attempt to put the monitor to sleep has been made), reconnect the monitor. OBSERVED RESULT kwin_wayland crashed and dumps its core. EXPECTED RESULT kwin_wayland doesn't crash.
