I had a similar issue and yes: sudo apt-get remove xserver-xorg-input-wacom
changes the behaviour. Previously, Settings>Input Devices>Trackpad showed no devices. Now, it shows my Wacom CTT-460. Also, mtdev-test still fails as above but geisttest seems to show the device working with pinches. (geisview fails because gtk is not installed.) Other sources say that the kernel module named "wacom", a *driver*, is distinct from the *Xorg input driver* named "xserver-xorg-input-wacom." Also, the kernel module named "evdev" is distinct from the Xorg input driver named similarly. I don't understand the difference, but /var/log/dmesg still shows a "wacom" driver being used for my device. I am running kubuntu 12.4b. My best guess it is an architectural issue: client vs server. I recall that Ubuntu is moving multitouch and gesture recognition to the client side (the windowing system and application, more or less) from the server side (Xorg, the X11 server.) IOW the Xorg input driver named evdev passes raw multitouch events on to the client (Qt) instead of interpreting them??? -- 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
