Can you give the output of "xinput list" ? Assuming you're using xournal 0.4.8 (or the current git, not very different) (if not, you should -- 0.4.8 has many important touchscreen fixes in it), did you specify the touchscreen device under Options -> Pen and Touch -> Designate as Touchscreen, and try turning on options like "Touchscreen as hand tool" and "Pen disables touch" ? There might still be some bugs, but at least the sort of behavior shouldn't happen if there are distinct devices for the pen and the touchscreen and the touchscreen device is If there aren't different xinput devices for pen vs. touch, then you're essentially out of luck as far as using the pen properly in Linux goes. > (2) Resting > palm on the screen triggers Unity 3- or 4-finger multi-touch gestures, > which either open the Unity HUD menu, or bring up drag handles on the > window. That's also pretty annoying and interferes with trying to ink. I don't know anything about Unity, but short of disabling the multi-touch gestures altogether in the Unity settings I don't think you can expect anything better. If all else fails, it's a big hammer but you can always run xinput disable "name of touchscreen device" before running xournal. Some people wrote scripts that automatically run this (or conversely enable) every second depending on whether the wacom pen is in proximity or not, but I'm not a big fan (but then I don't have that annoying Unity problem since I use gnome). > Has anyone looked into what it might take to make Xournal ignore touch > input If xinput reports a separate input device for the pen, get 0.4.8 and set up the options under Pen and Touch as works best for you. If you don't have a separate input device for the pen, you're out of luck, xournal has no way of telling your pen from your hand.
