Can you run hid-recorder
from hid-tools too please? Just to verify this is really in the HID reports and not the kernel somehow dropping reports. Thanks
Here you go hid-record.txt
Thanks, confirming, the pressure only changes on every second event so this is definitely a hardware limitation.
edit: filed libinput#973 for this now
@jigpu, @Pinglinux , @skomra, @Joshua-Dickens - do we know if this is a pen issue or a tablet issue? i.e. can we expect this behaviour on all tablets?
FTR, it looks like this is a pen issue rather than the tablet, with this udev-hid-bpf MR looking like it's the best solution.
This is libinput record
for my art pen :thinking:
The solution has been merged.
As exactly stated in #187 the Wacom Art Pen (KP701E2) only reports the pressure data every other response. This is not an isolated issue to a single pen. Have tested this with multiple art pens. I've also talked to others with Art Pens and when I get them to disable the high sensor stabilizers they have set in (painting) software, the pen pressure stepping also appears instantly.
Here is the readout for
libinput record
artpen.txtWould be great to tie the pressure smoothing to RawSample somehow for ArtPens. I'd be happy to help out in any way I can.
