This bug affects me too, with the "Atmel maXTouch Digitizer" touchscreen on the new Samsung XE700T1C (aka ATIV Smart PC Pro). After a while of touching the screen it gets locked and I'm no longer able to touch anything... the touch events appear to get accumulated and only released when another device clicks.
For example, if I'm using OnBoard (onscreen keyboard) to type into the Dash or a document, and I touch a bunch of keys nothing happens, but as soon as I click with my mouse or wacom pen, all the characters I had previously been touching are suddenly spat out into whatever text box I was in. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/946417 Title: "Cando" Touchscreen buggy since Precise - After the first few successful "clicks" on the touchscreen, new "clicks" are not registered anymore. Status in “xserver-xorg-input-evdev” package in Ubuntu: Confirmed Bug description: In the beta-1 of Precise, the "Cando" touchscreen of my Acer 1825PTZ does not work anymore. After the first few successful "clicks" on the touchscreen, new "clicks" are not registered anymore. I can still move the cursor via the touchscreen, however. When I switch over to the mouse in this state, it also stops registering clicks after a few of them. The mouse can still move the cursor, just as the touchscreen. Sometimes, the pointer will jump to an entirely different position, when I click a button on the mouse while the touchscreen is bugged out. If I do not use the touchscreen at all, and only the mouse, this behaviour does not seem to trigger. My touchscreen worked fine with Oneiric, so this a regression.
