Recently I upgraded ubuntu from 14.04 to 14.10 on my HP EliteBook 2760p. After that, all serial wacom devices (for the touchscreen) are gone:
serial wacom stylus
serial wacom eraser
serial wacom touch
xinput -list and xsetwacom --list don't show these devices and the Wacom Tablet section of the system setings reports 'no tablet detected' rather than showing the usual settings. Booting with the old linux 3.13 kernel makes no difference to the new version 3.16.
To find out what happened I played around on a spare partition with the following results:
1) fresh installation of 14.10 - result is the same like reported above: no touch devices
2) fresh installation of 14.04 - touch works out of the box
3) upgraded the fresh installation of trusty to utopic: touch devices gone again
4) manually changed repos to utopic after fresh installation of 14.04 and updated ONLY the xserver-xorg-input-wacom package: apt pulled some dependencies and installed without errors, touch devices gone (so it reproduces the error exactly as the full upgrade)

I haven't found a workaround, so far, but on my recherche I found a similar problem with some lenovo notebooks which have built in also the serial wacom devices. See http:// askubuntu. com/questions/ 541505/ thinkpad- x41-tablet- wacom-stylus- stopped- working- on-lubuntu- 14-10
So it may not only affect the HP EliteBook. Please, can somebody confirm that?
