XP-Pen Deco 01 V2 stops working when I press the upper pen button #641

Open dcarrera opened 1 year ago

dcarrera commented 1 year ago

I have an XP-Pen Deco 01 V2 and I have a weird and frustrating problem. The tablet generally works well. I can draw on Krita, pressure sensitivity seems to work, etc. The stylus has two buttons. The lower one acts like a mouse middle click button. The upper one makes the tablet stop working entirely.

To "fix" the tablet, I can unplug it and plug it back in, and then it goes back to normal.

I have created and attached all of the files that were requested in the "Collecting tablet diagnostics" page.

While producing these files I noticed two more surprising things:

  1. When I ran the 'uclogic-probe' command the stylus stopped working again, even if I didn't press the button. I 'fixed' that again by unplugging the USB and plugging it back in.
  2. When I ran the 'usbhid-dump' command and pressed the buttons, the tablet continued working normally. So whatever is causing the tablet to stop working is not something inside the tablet.

I am running Pop! OS 22.04 with Gnome and X11.

Thanks for the help.

Hi!

While the XP-PEN Deco 01 seems to be supported by DIGImend, I don't think that your tablet (v2) is supported. It has a different product ID and I don't see it listed.

You can confirm it by connecting your tablet and running dmesg. If you see something like:

[ 5576.132879] input: <your tablet name> as /devices/...
[ 5576.187009] hid-generic ...
                            ^ This is the name of the driver

It means that your tablet is handled by the hid-generic driver and not by DIGImend (uclogic driver). Feel free to share the log and I'll have a look.

I added support for a bunch of XP-Pen devices on the kernel lately. I don't have enough information from your log to be 100% sure, but I think that supporting your tablet should be straightforward.

Could you test these drivers, please?

First, download the source code: digimend-kernel-drivers.zip

The source code contains the code from DIGImend, the changes I made in the upstream kernel plus the changes required to add support for your tablet.

In order to install it, you'll need to install the kernel headers:

$ sudo apt-get install -y "linux-headers-$(uname -r)"

After extracting the code, cd into the source code and:

$ make
$ sudo make install

You can uninstall it running:

$ sudo make uninstall

More detailed instructions are available in the DIGImend README file.

After installing the drivers and reconnecting, dmesg should show that the uclogic driver is used for your device and, hopefully, your pen's buttons should work. Let me know how it goes!

For reference, this issue was reported, fixed and tested here: https://gitlab.freedesktop.org/libinput/libinput/-/issues/839

The patch is already in the kernel mailing list: https://lore.kernel.org/linux-input/20221226123456.14822-1-jose.exposito89@gmail.com/T/

Hi, thanks to the awesome digimend drivers, I run the Deco 01 v2. No doubt the patches have fixed the original issue, but just to add something that might be useful regarding right click/upper button, for both v1/2 of the Deco 01. I'd been able to piece together, when first starting to use it, how to add right-click, from looking at threads here, but can't find the thread where I detailed that. Currently running MX Linux, X11, with Mate desktop installed. I'm running 5.10 kernel but not a recent version.

On looking through the notes I keep, with not being very technical, lol, have noted that am running kernel/headers, digimend/dkms, libwacom and libevdev stuff, then add 2 files in 2 locations to enable the right click [e.g. colour pick] via top button.

10-xppen.hwdb into /etc/udev/hwdb.d ...

evdev:input:b0003v28BDp0905* KEYBOARD_KEY_d0045=332 KEYBOARD_KEY_700e0=fn KEYBOARD_KEY_700e2=fn KEYBOARD_KEY_70015=256 KEYBOARD_KEY_70018=257 KEYBOARD_KEY_7001c=258 KEYBOARD_KEY_7003c=259 KEYBOARD_KEY_7002d=260 KEYBOARD_KEY_70026=261 KEYBOARD_KEY_70067=262 KEYBOARD_KEY_70066=263

and

xp-pen-dec01.tablet into /usr/share/libwacom [sigh, text that appears as giant is a required part of the file, so copying the full text should be fine]

In Krita, I set tablet settings to 'use mouse events for right/middle clicks', and also have a note about deleting the Alt+Space shortcut in Mate, but I think the latter note I made was when I was running Sai2 via wine.
