Public bug reported:
The active stylus on my HP OmniBook x Flip Ultra 14 reports at extremely
low frequency (~10–25 Hz) under Ubuntu 24.04.4 LTS with kernel
6.17.0-14-generic. The pen input is choppy and unusable, while touch
input works normally.
The pen is a HP MPP tilt pen 2.0
Steps to Reproduce:
Boot Ubuntu 24.04.4 LTS on HP OmniBook x Flip Ultra 14.
Ensure kernel 6.17.0-14-generic is in use.
Run:
sudo libinput debug-events
And then i move the pen and compare the input events with touch on my
screen. The timestamps of the pen are 40-100 ms apart, which makes it
unusable.
I think this is the stylus in libinput:
