Title:
ALS (Ambient Light Sensor) wakes up the suspended Ubuntu
Status in linux package in Ubuntu:
Fix Released
Bug description:
After suspending the Laptop, ALS (Ambient Light Sensor) is waking it
up.
System Information -
Product Name: HP ZBook Studio x360 G5
SKU Number: 5LA90PA#ACJ
OS Information -
> uname -a
Linux *** 5.8.0-41-generic #46~20.04.1-Ubuntu SMP Mon Jan 18 17:52:23 UTC
2021 x86_64 x86_64 x86_64 GNU/Linux
> lsb_release -rd
Description: Ubuntu 20.04.2 LTS
Release: 20.04
I am able to disable ALS as follow -
> sudo modprobe -rv hid_sensor_als
modprobe: FATAL: Module hid_sensor_als is in use.
So, I blaclisted hid-sensor-als by appending following text in
/etc/modprobe.d/blacklist.conf -
# ALS
blacklist hid-sensor-als
Restarted the system and checked if the module is really blacklisted using -
> lsmod | grep hid_sensor_als
But the issue still persists that ALS wakes up the suspended Ubuntu.
Also, BIOS doesn't have the option to disable ALS.
