Bluetooh keyboard wakes up laptop just after suspension

Post by lenrok258 »

Hi everyone,

I'm struggling with waking up my mint linux from suspension using blue tooth keyboard (Logitech K380).
Waking up is enabled in BIOS and I'm able to do so with mouse click (wired).

Keyboard is visible in

Code: Select all

/proc/bus/input/devices 
I: Bus=0005 Vendor=046d Product=b342 Version=4201
N: Name="Keyboard K380 Keyboard"
P: Phys=b4:b6:76:e8:33:47
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5/2-1.5:1.0/bluetooth/hci0/hci0:34/0005:046D:B342.0004/input/input32
U: Uniq=f4:73:35:14:c7:e5
H: Handlers=sysrq kbd event21 leds
B: PROP=0
B: EV=120013
B: KEY=1000000000007 ff9f207ac14057ff febeffdfffefffff fffffffffffffffe
B: MSC=10
B: LED=1f
Event send from this "address" should wake up laptop as

Code: Select all

cat /proc/acpi/wakeup
returns
EHC1 S3 *enabled pci:0000:00:1d.0
Enabling this device (/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5/) to send wakeup event by

Code: Select all

echo enabled > /sys/devices/pci0000\:00/0000\:00\:1d.0/usb2/2-1/2-1.5/power/wakeup
makes laptop wake up by itself just after going to sleep.

I was suspecting keyboard is sending uncesesery events even if I don't press any key but it also happenes if I turn it of before puting laptop to sleep.

Have anyone experienced similar problem?

Is there any way to check who send the wakeup ACPI event and woke up the laptop?

Linux Mint 20.1, Cynamon (I'll post inxi -Fxz output in a moment)
