Also, could it be that the scroll issue > happens only in a certain application? It's not a "scroll" issue. The issue is that the "up" event is getting lost. It can be observed with any GUI elements, such as buttons. However, since the event is delivered upon any motion, there's no harm done with a button. Needless to say, this is not application specific. It may be GNOME specific though. FC-3 is far too old to be a good reference. I don't even know if it has a usable synaptics module in its pre-modular X. You may be looking at very different software stack. I don't think that you need to concern yourself with this too much at present. If X11 people (e.g. Kristian) present evidence that kernel fails to deliver an event, then we'll look at it. However it might help if evtest continued to work when X11 reads from /dev/input/eventN. It was an unpleasant surprise that it doesn't. -- Pete
