Thanks for the journal log; that's helpful. I don't see any messages from Libinput that the compositor was being too slow and discarding events, which means this is most likely not a KWin issue. I'd recommend you report it at https://gitlab.freedesktop.org/libinput/libinput/-/issues, following the instructions in the template to generate input logs as needed. Thanks! |
Created attachment 181369 [details] Full journal log from the boot where the issue occurred (generated with `journalctl -b -1`). Contains system messages from the session where the TrackPoint was not working and the cursor was stutterin ### SUMMARY After rebooting my ThinkPad L460 following a system update, on the next startup the mouse cursor was stuttering and moving very slowly, and the red TrackPoint was completely unresponsive. After one more reboot, everything started working normally. ### STEPS TO REPRODUCE 1. Install system updates 2. Reboot the system 3. Observe mouse/TrackPoint behavior on next boot 4. Reboot again — issue goes away ### OBSERVED RESULT - Mouse cursor was jittery and very slow - TrackPoint (red dot) was not working at all - After rebooting again, both issues disappeared ### EXPECTED RESULT - Cursor should move smoothly after any reboot - TrackPoint should work immediately every time ### SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20250508 KDE Plasma Version: 6.3.90 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.0 Kernel Version: 6.14.5-1-default (64-bit) Graphics Platform: Wayland ### ADDITIONAL INFORMATION - Laptop: ThinkPad L460 (LENOVO 20FVS20700) - CPU: Intel® Core™ i3-6100U @ 2.30GHz ×4 - RAM: 8 GiB - GPU: Intel® HD Graphics 520 - The issue occurred **after rebooting once post-update**, not immediately after the update - Input devices may have failed to initialize properly during that boot - Not reproducible consistently, but could affect others
