I see this same behavior on a Samsung Slate 7, which has an Atmel maxtouch multitouch touchscreen. Running Precise, with xserver-xorg- input-evdev 1:2.7.0-0ubuntu1.2 and xserver-xorg-core 2:1.11.4-0ubuntu10.8.
If I don't touch the touchscreen since the X server has started, xev reports the state of events as expected when using a mouse. 0x000 for the ButtonPress, 0x100 for motion with the button down and the ButtonRelease, then 0x000 after. However, after the touchscreen is touched once, the state becomes 0x100 for the first ButtonPress from the touchscreen and stays at 0x100 thereafter, even after the ButtonRelease. Keyboard keys, mouse clicks, mouse motion, etc. are all state 0x100 until the X server is restarted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1015183 Title: Inconsistent mouse events for Acer T231H multitouch monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1015183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
