Regression: since Linux 4.18rc1 Trust Flex Graphics Tablet incorrectly detected as mouse, so no Pen input device, no pressure detection, etc. #251

Hello!

I got recommendation to contact DIGIMend project in this bugreport. Actual regression that I want to report is described in upstream bugtracker.

JacekJagosz commented 5 years ago

It is still a problem for me on kernel 5.1, without or even with Digimend drivers installed. I know it probably needs to be fixed in the kernel, but how could I report it? output of xsetwacom list: UGTABLET TABLET WP5540 stylus id: 15 type: STYLUS

It's already reported as you can see here: https://bugzilla.kernel.org/show_bug.cgi?id=202195

JacekJagosz commented 5 years ago

I am following that, but still nothing has been done for months. Nobody took any action. I really beg any of you who is capable to try and fix it. Otherwise I will need to buy a new tablet, even though I really liked this one.

I tried to contact @spbnick via e-mail but he didn't answer. Maybe my message got into spam folder, I don't know.

You could try to contact Benjamin via e-mail. Issue was introduced after his commit and I just don't know anyone else, besides @spbnick, who is capable of resolving this in upstream.

Hi @JacekJagosz, @RussianNeuroMancer! I got @RussianNeuroMancer's e-mail and took a look at the issue, but I simply didn't have time nor energy to tackle it yet. I'm taking a break from DIGImend at the moment, so it will still take a while for me to get to it. Sorry about that.

JacekJagosz commented 5 years ago

@spbnick As long as someday somebody fixes it I (and probably everybody interested) am fine with it. I was just worried that a bug introduced in 4.18 and not even fixed in 5.2 isn't popular enough to ever get fixed. If in a few months you were able to fix it, I would be really happy!

Oh poop I'm seeing the same problem. My tablet is now seen as a touch mouse ...

RussianNeuroMancer commented 4 years ago

@spbnick hi, I wonder if you have time currently to look into this issue?

RussianNeuroMancer commented 4 years ago

Unfortunately, with Linux 5.5/5.6 (maybe earlier, didn't check) this tablet regressed further: https://bugzilla.kernel.org/show_bug.cgi?id=202195#c8 (Comment 8).

spbnick commented 4 years ago

I don't have time right now, but I put it into the queue for the next release, and should get to it in a few weeks.

spbnick commented 4 years ago

Looking at the bug report I see that the tablet in question was never supported by the DIGImend drivers and was handled by the generic HID driver. The tablet reuses the name of the tablet with completely different hardware, although the manufacturer assigned it a different item number (21259 vs 16937).

The change in the kernel causing the tablet to break is unfortunate, but I believe @bentiss was heading in the right direction there and we probably shouldn't be reverting it. Instead, we should have the tablet supported properly. I made a brief stab at that in #412. Please test and report results there.

It's seems like uclogic driver is loaded, but "libinput debug-events" doesn't report pressure (and there is no pressure in Krita too).

spbnick commented 4 years ago

Alright, a guess didn't work. Could you please post the output of uclogic-probe for your tablet, plus the usbhid-dump -es output for your tablet when you do a stroke with the pen? See details in https://digimend.github.io/support/howto/trbl/diagnostics/

Also, please comment in the PR instead.
