[Bluez-users] crazy mouse

[-- Attachment #1.1: Type: text/plain, Size: 1010 bytes --]

Hello all,

Thanks to Marcel to have so quickly publish the patch 2.6.16-mh1 after
my request ! I've patched a 2.6.16.19 kernel and all seems to works
after the reboot.

But my mouse (Logitech MX900 BT) move strangely. The movement seems to
be by "hop" on the screen, I've never see this before, it's annoying ...

For a better explanation, its as if the mouse send is move data normally
but X and the console (gpm) receive it asynchronously and at a point the
cursor "freeze" a 1/4 of second and move quickly at the real position,
all along the move of the mouse ...

Very strange no ?

After rebooting on my 2.6.15-mh2 kernel all works good !

Any idea ? Or maybe a procedure to debug that I can do ?

I've a Gentoo on amd64, full 64 bits, last bluez utilities on gentoo.
For more information just ask me.

Best regards.

Didier Link

check your Xorg configuration. You might have configured two inputs and
the events add up. There was a report about that some time ago.

Yes, I've seen this but this not apply to my case, I've not 2 inputs and
this is the same situation on the console (the linux one, not in X !)
with the gpm daemon. My device for mouse is only /dev/input/mice.

And by "hop" it's not a real acceleration, I will try to explain
better : between positions x and y at screen they have "a time", from x
and during the first quarter of this time the cursor move correctly and
sudenly freeze, at the end of the time the cursor move instantly at y.
This scenario again and again all along the move of the mouse :-/

This appear only with kernel 2.6.16.19-mh1, the 2.6.15-mh2 is perfect
with the same configuration !?!?

Any idea ??

I will retry this evening ...

Regards.

Didier

Hi,

you could execute:

  # hcidump -t -X -V -B -w log

then move your mouse a little bit and then hit ctrl-c and do:

  # gzip -9 log

And then send us log.gz or send us a link to somewhere we can download
it. That way we might have an idea of what is going on. :-)

Best regards,

Hmm.. I can't see anything unusual. Only the automatic switch to sniff
mode feature trying to hold the connection in active mode and your
mouse turning it back to sniff mode. Could you give the 2.6.16-mh2 a
try? It doesn't contain the automatic switch to sniff mode feature and
we'll be able to see if that's causing your mouse problems.

Best regards,

please use 2.6.16-mh1 and the attached patch. That should make it work
again as expected.
