It doesn't work on Asus Zenbook Flip 14 UN5401Q (AMD)

[Mark12870]

Device: Asus Zenbook Flip 14 UN5401Q (ASUSTeK COMPUTER INC. Zenbook UN5401QAB_UN5401QA)
OS: Ubuntu 22.04.1 LTS

When I flip the device, nothing happens.

Debug log:

marek@marek-zenbook:~/Downloads/asus-fliplock-driver-master$ LOG=DEBUG sudo -E ./asus_fliplock.py
[sudo] password for marek: 
DEBUG:Asus fliplock:Detect wmi hotkeys from N: Name="Asus WMI hotkeys"

Hi, thank you for creating an issue.

Can you please run this command sudo libinput debug-events and do a flip with your laptop? Post the result here. You should see this as me (this driver reacts to these events):

$ sudo libinput debug-events
...

Ye, I was just debugging the problem and it looks like it doesn't emit the event at all. Probably the device is not supported properly in the kernel? I was thinking about this place: https://github.com/torvalds/linux/blob/master/drivers/platform/x86/asus-nb-wmi.c

[ldrahnik]

It might be a reason. Do you use intel as me or amd? I already met someone with amd but sorry, do not know if he solved / figured out what was the problem.

[ldrahnik]

What you can do is check if the kernel module is installed / supported by your distro (I use Ubuntu 20.04 based distro), and is running without problems. If is amd not your case I recommend you try to enable module by yourself & disable module what your laptop is using atm and I believe it should work. Good luck. Stay in touch!

[ldrahnik]

Atm your laptop when is flipped to tablet mode disable at least the keyboard or not?

[Mark12870]

I have AMD. It doesn't disable anything.
I think the kernel module is loaded. I see all these inputs:

marek@marek-zenbook:~$ ls /dev/input/by-path/
pci-0000:04:00.4-usb-0:2:1.0-event  platform-AMDI0010:03-event-mouse
platform-AMDI0010:00-event          platform-AMDI0010:03-mouse
platform-AMDI0010:00-event-mouse    platform-asus-nb-wmi-event
platform-AMDI0010:00-mouse          platform-i8042-serio-0-event-kbd
platform-AMDI0010:03-event-kbd

I think platform-asus-nb-wmi-event should be emitting the event.

(And sorry Im answering late, I don't see any notification anywhere)

Hey, did anyone ever get this fixed, I have the same laptop and have this problem?
Thanks

[beankylla]

I have a UN5401RA and am dying to see this fixed!
If there is anything i can do to help, glad to do it! Fedora 38 under the hood here.
Thanks a lot for the touchpad driver btw works like a charm!

[ldrahnik]

@beankylla Hello there :)

Thanks a lot for the touchpad driver btw works like a charm!

Glad to hear that, put a star if you like and do not hesitate to create any issue in case you face something.

Please try to run this command $ sudo acpi_listen and then flip laptop. Do you see as output any row which contain something like video/tabletmode?

[ldrahnik]

@beankylla ping

In my case I see:

$ sudo acpi_listen
[sudo] password for ldrahnik:          
 video/tabletmode TBLT 0000008A 00000001 # flip to tablet mode
 ...
 video/tabletmode TBLT 0000008A 00000000 # flip back to laptop mode
 ...

What do you see on AMD device?

[beankylla]

Hi!

nope nothing happens :(
absolutely no feedback / line stay emtpy

[ldrahnik]

@beankylla Try $ sudo libinput debug-events, do you receive any events during switching your laptop to tablet mode and back? (KEY_F22/F23 for example)

[beankylla]

@ldrahnik nope not if i don't accidently touche screen or keyboard, just tried again ^^'

edit: i just tried again with Fedora 39 and no dice. even kernel 6.5.10 does not seem to have what we need ^^'

I've got similar issues to what's described here, the output of sudo libinput debug-events gets me:

This was also after rotating the screen and flipping it to tablet mode. Model UN5401, AMD 6800H.

So, no "switch" event, or tablet mode callout.

Having done a lot of searching, it seems like this might be part of the "amd_sfh" module. I was also hoping to find a manual script for swapping to tablet mode, but it seems like that happens at a lower level, and relies on the libinput events.

I would love to report this upstream to the appropriate place to help debug, but I don't know where that would be. Can someone point me towards it?

[Buskebam]

Any luck finding the place where we should report/ try to fix this upstream? Having the same issue unfortunately.

[Sporknife]

This bug has been open for some time now. I hope it gets more attention.
https://bugzilla.kernel.org/show_bug.cgi?id=214675

[Buskebam]

We got an update

AFAIK the issue rely on the fact that amd-sfh do not support lid angle sensors as of today, but I'm not sure if this laptop use that driver or ASUS has invented something else for handling it and therefore the driver is fully missing.

Not sure how we can continue our search towards the correct place to report a bug.

[Sporknife]

Found some documentation. Go to https://docs.kernel.org/admin-guide/abi-testing.html and search for /sys/bus/surface_aggregator/devices/01:0e:01:00:01/state.

But as far as I understood, this is only for testing/debugging. I think.

[ldrahnik]

I developed a driver for laptop Zenbook UN5401QAB (AMD), Vivobook TM420IA (AMD) and other laptops with this problem https://github.com/asus-linux-drivers/asus-accel-tablet-mode-driver using accelerometer

[ldrahnik]

Closing as this issue is not related to this driver and exists mentioned solution
