Hi!
Just installed the just released 3.17 kernel and found a bad behavior of
the new Synaptics driver on my Thinkpad Yoga which has the new Synaptics
clickpad enabled touchpad:
psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1,
caps: 0xd002a3/0x940300/0x12f800, board id: 2911, fw id: 2560
The issue is that now a button release is only issued after the finger
has completely left the touchpad and not when releasing the physical
button. Is this physical button now called FORCEPAD? Anyway, this is
pretty annoying. Double clicking become a real pain.
I did comment out the new
if (SYN_CAP_FORCEPAD(priv->ext_cap_0c)) {
...
and everything is back to normal again, i.e. when I do release the pad
physical button but keep the finger on the pad, the button release event
is issued properly.
Hmm, the forcepad code should only activate if the devoice do4es not
have physical buttons at all. Let me see what's the diffference in
capabilities between your and mine touchpads...
OK, so your extended caps are 0x12f800 while on my forcepad they are
0x12e800. The forcepad bit is supposed to be bit 15, so it is set for
both our devices, but bit 12 (counting from 0) is different.
Andrew, Chris, could you please tell us what bit 12 indicates? In fact,
if you could share the updated description for all currently defined
capability bits that would be awesome.
Thanks!
Hmm, looks like I got incorrect information about the ForcePad
capabilities bit and unfortunately there does not seem to be a
capabilities bit for ForcePad on PS/2. Too bad that wasn't caught before
3.17 was released. Bit 12 is for "uniform clickpad" which means that the
whole clickpad moves when you press it as opposed to it being hinged at
the top. That makes sense that a ForcePad would not have that capability.
Also, it's weird that the firmware ID printed above is not correct. I
would expect a 7 digit number starting with 1.
