Are you using a Gnome 3 based environment, perhaps with gnome-shell version 3.16.x ? If so, the problem is actually that Gnome Shell itself has become very buggy about dealing with touchscreens, and freezes the user interface for random amounts of time when both a touchscreen and another input device are sending events. See my August 13 message to this list with subject "XNoHands". > I could be in the middle of annotating, and suddenly both the stylus and > the touchscreen cease to work. then I wait what appears a random amount > of time, and it works again (or try to click outside xournal). Does the problem specifically affect xournal, or does your whole system (rather, just the GUI) freeze when you use the stylus and touchscreen simultaneously? (test: with or without running xournal, touch screen with one hand and use pen with the other, does the system immediately freeze?) If so: get xnohands or use a similar hack. > by the way, I am using the proximity hack (disable touch when the pen is > close), maybe this is the reason of the issues. But it appears that even > if I drop the pen and only use my finger, I get unresponsive moments. Which proximity hack do you mean -- "Pen disables touch" in the Xournal Options menu, or XNoHands / similar to wholly disable the touchscreen when the pen is near the screen ? "Pen disables touch" in Options menu merely discards touchscreen input events from xournal processing when the pen is near the xournal window, but not without Gnome Shell first getting itself thoroughly confused and freezing your display in the first place... so the only solution I know is to entirely disable the device from the xinput configuration. (this is what xnohands does).
