Wacom stylus not identified/available (ACER SPIN 5)

[crysman]

There is "No stylus found" in the Settings. Stylus itself is working flawlessly in Windows 10 OS. What shall I do to make it work in Ubuntu 20.04 (GNOME)?

Here is the xsetwacom output:

xsetwacom --list
Wacom HID 495F Pen stylus id: 9 type: STYLUS
Wacom HID 495F Finger touch id: 10 type: TOUCH
Wacom HID 495F Pen eraser id: 18 type: ERASER

PS: I am currently forced to use these kernel boot parameters:

    i8042.nopnp=1 pci=nocrs

(because of this bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884232 )

Many Thanks!

Thank you for your bug report, could you add the output of this command?

$ libinput list-devices

(you might need to install libinput-tools first)

[Daniel van Vugt (vanvugt)]

In the past I've noticed this problem on some machine(s) with a built-in stylus too.

[Sebastien Bacher (seb128)]

@Daniel, did you check at the time if the issue was specific to the settings or if the stylus was not correctly picked by libinput?

[crysman (crysman)]

Many thanks for helping with this, here it is (attached), Sebastian...

[Sebastien Bacher (seb128)]

Thanks, searching a bit upstream it sounds like the right command is rather

$ libwacom-list-local-devices

could you get the output from this one? https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/790 upstream seems similar

[crysman (crysman)]

there is unfortunately no output from that command :( :
""""
$ sudo libwacom-list-local-devices && echo DONE
DONE
""""

I will have a look into that gitlab issue later on, thanks for now

[Sebastien Bacher (seb128)]

if it's not listed it sounds like something worth reporting upstream on https://github.com/linuxwacom/libwacom/issues/

I am first working on this kernel bug to actually have no weird boot kernel parameters in order to have functional touchpad and touchscreen in the first place...

Hi, just to say that for me
adding
i8042.nopnp=1 pci=nocrs
works very fine :
I had back :
- touchpad
- touch screen with automated rotation (usefull in tablet configuration)
- stylus recognition with buttons and intensity sensor (tested on xournal++) and appearing in the wacom parameters

Thanks a lot.

Config : spin 5, sp513 54N
- with 1TB ssd, 16GB RAM,
- dual boot using BIOS option AHCI
- Linux Mint 20 Cinnamon
- a NTFS partition to share docs between Linux and Win

[JB Cools (coulaud)]

Oooups :
I just checked that the rotation of the screen works, but not the rotation of the "touch" part of the screen (so there is no coherence between touch and orientation when the screen rotate)

[crysman (crysman)]

@coulaud I had noticed that, too, but testing it today... it seems to work just fine.

Unfortunately, user experience with pen/stylus on GNU/Linux is MUCH WORSE than in Windows 10 :( namely because it behaves just like if it was a mouse - simple mouse pointer. In Win10, it is smart and you can move the screen... I wish it could be the same in my primary OS (here in Ubuntu)
