I have a wacom build-into my fusitsu t-900. I also have experienced the loss of finger input when upgrading to Xenial. However the issue was not the kernel itself, but the fact that on the previous version of ubuntu (15.10) I had to run from my /etc/rc.local:
/usr/bin/inputattach --always -w8001 /dev/ttyS4 In order for the wacom to work. Now this actually is messing things up. Now It just works without the inputattach thing. Can you reproduce the bug on a brand new (live dvd) installation? my xinput without the inputattach running. $ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=14 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)] ⎜ ↳ Serial Wacom Tablet FUJ02e7 stylus id=16 [slave pointer (2)] ⎜ ↳ Serial Wacom Tablet FUJ02e7 eraser id=17 [slave pointer (2)] ⎜ ↳ Serial Wacom Tablet FUJ02e7 touch id=18 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Fujitsu FUJ02E3 id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Fujitsu FUJ02B1 id=9 [slave keyboard (3)] ↳ Fujitsu FUJ02BF id=10 [slave keyboard (3)] ↳ Power Button id=11 [slave keyboard (3)] ↳ CNF8248 id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1613134 Title: wacom touch screen does not recognize finger touch Status in linux package in Ubuntu: Incomplete Bug description: After Updating to Xenail, the touch screen does not recognize finger touch as input, stylus and eraser are still recognized.
