You have been subscribed to a public bug: I found a thread at https://lists.launchpad.net/multi-touch-dev/msg00798.html saying multitouch now works in Ubuntu's Qt and mentioned the Qt touch demos. Two finger pinch-zoom using the touchscreen works in Firefox on this hardware (HP EliteNook 2760p) out of the box- but none of the Qt multitouch Qt demos (eg fingerpaint, pinchzoom) from qt4-demos package work.
I tried to follow https://wiki.ubuntu.com/Multitouch/Testing but got stuck at https://wiki.ubuntu.com/Multitouch/Testing/CheckingMTDevice - the only plausible sounding device out of these.. $ sudo lsinput|grep name name : "Sleep Button" name : "Lid Switch" name : "Power Button" name : "AT Translated Set 2 keyboard" name : "HP HD Webcam [Fixed]" name : "HP WMI hotkeys" name : "PS/2 Generic Mouse" name : "SynPS/2 Synaptics TouchPad" name : "ST LIS3LV02DL Accelerometer" name : "Video Bus" name : "HDA Intel PCH HDMI/DP,pcm=3" name : "HDA Intel PCH Line In at Sep Rea" name : "HDA Intel PCH Mic at Ext Right J" name : "HDA Intel PCH Line Out at Sep Re" name : "HDA Intel PCH HP Out at Ext Righ" was the synaptics touchpad at /dev/input/event7 but: $ mtdev-test /dev/input/event7 error: could not open device $ sudo mtdev-test /dev/input/event7 error: could not grab the device Also, xinput_calibrator shows the touchscreen as this, which didn't show up in lsinput: $ xinput_calibrator --list Device "Serial Wacom Tablet stylus" id=13 Device "Serial Wacom Tablet eraser" id=15 Device "Serial Wacom Tablet touch" id=16 https://wiki.ubuntu.com/Multitouch/HardwareSupport says that Wacom should work.
