I am also using deskflow as the client, IE it is receiving events from another in this case Linux machine. In the following slightly modified code was triggered if the screen was locked, in this case `device` was returning as NULL. The code below is not a workable solution as it allows input into the lock screen's password box but will never actually unlock the screen. ``` case EIS_EVENT_FRAME: { auto device = eventDevice(event); if (!device) { qCCritical(KWIN_EIS) << "EventDevice NULL"; break; } qCDebug(KWIN_EIS) << "Frame for device" << device->name(); if (device->isTouch()) { Q_EMIT device->touchFrame(device); } if (device->isPointer()) { Q_EMIT device->pointerFrame(device); } break; } ``` To work around the previous case I disabled the lock screen and got the following crash. Which again points to `auto device = eventDevice(event);` being NULL in the following code block. case EIS_EVENT_POINTER_MOTION_ABSOLUTE: { auto device = eventDevice(event); const double x = eis_event_pointer_get_absolute_x(event); const double y = eis_event_pointer_get_absolute_y(event); qCDebug(KWIN_EIS) << device->name() << "pointer motion absolute" << x << y; Q_EMIT device->pointerMotionAbsolute({x, y}, currentTime(), device); break; } My guess is I need some logging / debugging somewhere in where the events are being created, I haven't been looking through the codebase quite enough to know where that would be yet. My build Info is below it is the 6.6 patches from https://invent.kde.org/plasma/kwin/-/merge_requests/8602 that should be unrelated but are also on my build ``` Operating System: openSUSE Tumbleweed 20260207 KDE Plasma Version: 6.5.91 KDE Frameworks Version: 6.22.0 Qt Version: 6.10.2 Kernel Version: 6.18.8-1-default (64-bit) Graphics Platform: Wayland Processors: 16 × 11th Gen Intel® Core™ i9-11950H @ 2.60GHz Memory: 48 GiB of RAM (46.8 GiB usable) Graphics Processor: NVIDIA RTX A2000 Laptop GPU ``` -- You are receiving this mail because: You are watching all bug changes.
