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
