[ubuntu] Touchscreen locking mouse events

view story

http://ubuntuforums.org – Hello! I have an Acer 231H touchscreen connected to a rather freshly installed Ubuntu machine (it's a very old Intel Mac mini, but I don't think it's what causing the problem). The touchscreen seems at first to work quite well at first, but after a seemingly random amount of clicks, all mouse events appears to infinitely lock up in a very peculiar fashion. Basically, when I release my finger from the screen, it instantly triggers a mouse down event at what I think was the position of the last mouse down event, and keeps holding that until I click somewhere else (whereas it repeats).
