[SOLVED] Power button not detected

I have a custom made laptop (Slimbook TITAN), and for some reason the power button is not detected anymore: this is causing, i think, the fact that I can't resume from suspend by pressing the power button, so I have to shut it down forcibly. I'm running arch on the 5.17.3 linux stable kernel, and the problem remains even with the lts version regardless of the desktop environment.

Re: [SOLVED] Power button not detected

sudo libinput list-devices: http://0x0.st/ochq.txt
cat /proc/acpi/wakeup:     http://0x0.st/ocFI.txt
xinput:                                 http://0x0.st/ocFU.txt

my /etc/X11/xinit/xinitrc:   http://0x0.st/iUvk.bin

I have disabled Windows Fast-Boot but nothing changes, and I have no idea how I should fix my xinitrc.

Re: [SOLVED] Power button not detected

The power button is detected by libinput

Device:           Power Button
Kernel:           /dev/input/event0

and forwarded to xinput

 Power Button                            	id=8	[slave  keyboard (3)]

But it's not in the DSDT

Device	S-state	  Status   Sysfs node
GP17	  S4	*enabled   pci:0000:00:08.1
GPP1	  S4	*enabled   pci:0000:00:01.2
GPP0	  S4	*enabled   pci:0000:00:01.1

You can check lspci to match the devices that can (and are enabled to wake the system from hibernation/s4)

Since you apaprently have a parallel windows, make sure to reboot windows (twice for voodoo reasons) after disabling fast start (what is NOT the fast-boot feature in your BIOS) and:
can you hibernate windows and wake that w/ the power button?

I have disabled Windows Fast-Boot but nothing changes, and I have no idea how I should fix my xinitrc.

The bottom line is jsut my signature w/ stuff I need to tell people very frequently ;-)
Your xinitrc is fine, but it's not even clear that you're using it. And it's not relevnt to subject at hand either.

Yes I can hibernate and wake Windows 10 by pressing the power button, and the problem persists in Arch even after rebooting in Windows two times.

Re: [SOLVED] Power button not detected

Try to lie to the acpi, pass eg

acpi_osi=! acpi_osi="Windows 2012"

to the kernel, https://wiki.archlinux.org/title/Kernel_parameters

Edit: oh, and see whether there BIOS updates for the device.

Re: [SOLVED] Power button not detected

When i set those kernel parameters my system won't boot, and there are no updates available for my BIOS. I should have noted that I've been using Arch Linux on this machine for almost a year and I've never had this kind of problem before.

Re: [SOLVED] Power button not detected

So the obvious question is what has changed between "almost a year" and "anymore".
The obvious answer would be a kernel update but since the LTS kernel is affected likewise, that's probably not it?
Is the power button still in the wakeup device list of eg. the installation iso?

Re: [SOLVED] Power button not detected

Ok I fixed the problem by downgrading the kernel to the 5.17.2 version released on 10 April, but the outputs of

sudo libinput list-devices
cat /proc/acpi/wakeup
xinput

are the still the same. Other than that everything seems to work fine, thanks a lot!

Re: [SOLVED] Power button not detected

the problem remains even with the lts version

Still true?
Also maybe post the output of lspci so we see what's in the DSDT
