If I boot into Windows 11 once and then shut down (not restart) and boot in= to Linux, the accelerometer works normally =E2=80=94 it appears under /sys/bus/iio/devices/iio:device3 and monitor-sensor reports data. After a full power-off or Linux reboot, it disappears again until I boot Windows again. Steps to reproduce: 1.Power off laptop completely. 2.Boot directly into Linux. 3.Run: ls /sys/bus/iio/devices monitor-sensor no accelerometer device, monitor-sensor also shows no accelerometer 4.Boot into Windows 11, let it load fully, then Shut down (not restart). 5.Boot Linux again =E2=86=92 accelerometer now present and monitor auto rot= ation works. 6.Reboot Linux =E2=86=92 accelerometer disappears again. Expected behavior: the accelerometer should initialize on a cold boot, without needing a prior Windows session. Actual behavior: No IIO devices appear on cold boot; accelerometer is only initialized after Windows has run once. Please let me know if you need any additional outputs. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
