There isn't one. Trying to use a touchscreen to run regular desktop linux has major usability problems, as I'm sure you've noticed!
My point is there is no mystery bug or hardware problem that's going to be solved by looking in logs. evdev's buttom emulation only works for touch pads, not touch screens. -- 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/1084938 Title: evdev settings doesn't work at all Status in “xserver-xorg-input-evdev” package in Ubuntu: Incomplete Bug description: My machine is the new Samsung XE700T1C-A01CA, aka ATIV SmartPC Pro. It has the same touchscreen as the previous Series 7 slate, the Atmel maXTouch Digitizer. I modified /usr/share/X11/xorg.conf.d/10-evdev.conf to add the following options to the touchscreen section: Option "EmulateThirdButton" "1" Option "EmulateThirdButtonButton" "3" Option "EmulateThirdButtonTimeout" "750" Option "EmulateThirdButtonThreshold" "50" and restarted X. Running xinput list-props shows that these properties are indeed set for the Atmel touchscreen device. However, when I touch and hold my finger in the same spot on the screen, nothing happens! I'm not sure what other files or output dumps would be useful for this bug (I'm a programmer but consider me a user as far as this stuff is concerned), so please let me know what else would be helpful and I will include it.
