Note, this bug does not only apply to USB digitizers but to built-in digitizers in some 2-in-1's as well (I am experiencing exactly the same behavior on a fresh install of 16.10 but instead with the pen on my lenovo miix 700 tablet, 100% vanilla drivers from the ubuntu install).
The pressure events show up just fine when watching from evtest, but xinput never seems to get ABS_PRESSURE updates. xinput sees the device axis just never gets update, which pins the pressure at zero. This is not a bug at the driver level, It's almost definitely some kind of regression in xorg/xinput/touch code.. Since the pressure is stuck at zero, this bug doesn't just stop pressure sensing, it's a total creative showstopper - makes it impossible to draw in any of the various art programs because pressure=0 --> nothing gets drawn in most programs, Krita segfaults, etc. etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639337 Title: Ubuntu 16.10 Abs_pressure not reported from kernel evdev to xserver- xorg-evdev To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1639337/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
