@Alex Hung (alexhung) Thank you for the temporary tweak.
After disabling XHC as wakeup, ALS is not waking up the suspended Ubuntu.
But, there should be some fine way to stop only ALS from wakeup rather than the
XHC (USB 3.1 controller) whole.
I think this seems to be a bug.
Fo the moment I did this -
1. Create a script file wherever you wish. Ex: `~/Scripts/disable-
devices-as-wakeup.sh`.
```bash
#!/bin/bash
declare -a devices=("XHC") # <-- Add your entries here
for device in "${devices[@]}"; do
if grep -qw ^$device.*enabled /proc/acpi/wakeup; then
sudo sh -c "echo $device > /proc/acpi/wakeup"
fi
done
```
2. Test it by executing it from the terminal.
3. If everything is okay then let's make a service.
`touch ~/Scripts/disable-devices-as-wakeup.service`
`chmod u+x ~/Scripts/disable-devices-as-wakeup.service`
~/Scripts/disable-devices-as-wakeup.service -
```bash
[Unit]
Description=Disable devices as wakeup
[Service]
ExecStart=/home/username/Scripts/disable-devices-as-wakeup.sh
Type=oneshot
[Install]
WantedBy=multi-user.target
```
4. Copy paste or move the service to `/etc/systemd/system/`.
`sudo cp ~/Scripts/disable-devices-as-wakeup.service
/etc/systemd/system/`
5. Enable the service.
`systemctl enable disable-devices-as-wakeup.service`
6. Restart the OS and check the status.
`systemctl status disable-devices-as-wakeup.service`

Title:
ALS (Ambient Light Sensor) wakes up the suspended Ubuntu
Status in linux package in Ubuntu:
Confirmed
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.
