Some more tests done. First of all, I made tests for 2.6.38.2 and it
seems to work just as well as on 2.6.37.5 which I had before.
Anyway, when doing more tests I noticed few new odd things in
gestures, things that as far as I remember worked better in 0.10.11
(better as in better than now, but not necessarily 100% correctly) so
I believe this stuff can be labelled as regressions:
First of all it's very very easy to generate multiple (usually 2 or 3)
RMB events when tapping second finger. It happens almost every time
for me. Is there some parameter to control it? LMB tapping works just
well with my setup. (I'm doing simple tests with: "xev | grep
Button"), maybe RMB events aren't respecting some parameters? Or
maybe, after successful tap and RMB generated, it should wait another
TapTime before accepting next event like that?
Second thing is that when I align fingers correctly for scroll and
start moving them, for some time (approx half, maybe quarter of
second) the cursor moves and after that time, it starts to generate
normal scroll events like it should.
There is also one thing that was reported for earlier versions too,
i.e. the jumps. Lets say I label fingers as A and B, If I put fingers
on the tablet in order A then B I have to remove them in exactly
reverse order, like B then A, or the cursor will jump by value that is
I believe difference between place where finger A started gesture to
on tablet where it is put now. Simple experiment:
1) Put finger A in top-right of tablet
2) Put finger B right to it
3) remove finger A from tablet
4) remove finger B from tablet (actually, no gesture or events have to
be generated during this as far as I see)
5) put finger in bottom-left corner, you should observe very big
absolute jump. The xev reports something like:
MotionNotify event, serial 40, synthetic NO, window 0x1800001,
root 0x15d, subw 0x0, time 1918061, (1654,22), root:(1654,43),
state 0x0, is_hint 0, same_screen YES
MotionNotify event, serial 40, synthetic NO, window 0x1800001,
root 0x15d, subw 0x0, time 1919525, (1004,386), root:(1004,407),
state 0x0, is_hint 0, same_screen YES
MotionNotify event, serial 40, synthetic NO, window 0x1800001,
root 0x15d, subw 0x0, time 1919561, (1004,386), root:(1004,407),
state 0x0, is_hint 0, same_screen YES
(those are 3 events, just before jump, the one generating jump and one
after the jump. There are no other events in between)
I will play with it more, but those are all odd things I found for now
Cheers,
Andrzej.
