I am experiencing the same problem as animitim (stylus input seems to jump), and I confirm that the issue is related to the latest xserver- xorg-core.
Reverting to previous version: apt-get install xserver-xorg-core=2:1.10.1-1ubuntu1 Solves the problem and pressure works fine with the qt version from utouch ppa (or the one from Scott Kitterman). So I guess we have to open an issue against xserver-xorg-core... -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to pencil in Ubuntu. https://bugs.launchpad.net/bugs/762938 Title: Wacom Pressure broken with Qt applications To manage notifications about this bug go to: https://bugs.launchpad.net/koffice/+bug/762938/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
