Have you thought of using xscope? from http://cgit.freedesktop.org/xorg/app/xscope It would snoop on the net traffic between the X server (including the Xorg driver say synaptics or evdev) and the X client (say Qt and app.)
Possibly the xscope tool is not up to date with XI2 protocol packets, but if not, maybe it would dump them in a raw format without interpreting them in the log. A binary strategy: if you see touch events between the two, suspect Xclient (Qt and whatever touch support Ubuntu added), otherwise suspect X server the driver. You could also snoop between X server and Compiz/uTouch which is also X client. Again, maybe uTouch is improperly grabbing. Also, check the commits to they Synaptics Xorg driver. It seems active. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xf86-input-wacom in Ubuntu. https://bugs.launchpad.net/bugs/901630 Title: multitouch + qt doesn't work (eg fingerpaint demo) with wacom serial touchscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/901630/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
