One more comment - the problem I experience is due to bad fabric of the case of the laptop, which causes phisical contact between the mouse touch and the display when display of laptop is closed.
Ahyway on windows there is no problem. Seems the touch part of the touch display is turned off when the display light is turned off. Under Linux the display turns off but the sensing touch part of the touch display is constantly on. I need to have the laptopn slightly (3-5 mm) open so there is no physical contact but not opened too much as the display will turn on and will automatically turn off my external monitor. Therefore I belive teh correct behavior of the driver or component should be when the LCD of the laptop turns off (even when the screen is open) the touch functionality of the same touch screen should also be off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1477276 Title: Touch functionality of touch screen enabled when screen is off and display closed.
