I initially reported this issue, and the issue is best summarized in the bug summary at the top and in comment #1 providing more detail. Vincent's issue is best summarized in comment #6. > At least partially, it sounds to me that the issue that MacRules/Vincent > is having may be driver/firmware-related?

Correct, I think Vincent's issue may be driver related. > However, Chase you mentioned a fix that is targeted for Natty.

I was answering his question in comment #7 as though it were about the original issue I filed the bug for. > "The other thing is, when I use the driver that does not send the mtY and mtX > (both) then this issue also does not occur. > So linking all that, I would think that when a touch is performed, some > mechanism checks if both mtX and mtY are there and if so, tries to determine > something about a simple touch that couses a different interpretaton to X > then expected." > > Chase, to be explicit: > * do you think that MacRules/Vincent's issue is grail-related? > * if there are two issues at play in his comment, is one of them > appropriately associated with this bug? > * if so, which one? > * if one or more of his issues aren't grail-related, where should they be > filed? > * are there files or any command output that I think it's most likely driver related. I don't think it's related to my initial bug report in any way. I would file the bug against the utouch project since that's where we seem to dump bugs that aren't obvious as to which package they truly belong. > MacRules/Vincent: on the calibration side of things, my N-trig device > was also consistent with the placement of the cursor (position-wise). > However, many (most) times it would simply not interpret a touch unless > I pressed very hard.

Vincent, If you could, please file a new bug report for your issue and respond to Duncan's questions there. It will make bug tracking much easier.
