I've got a strange problem, after recent upgrade of kernel to 3.6 my touchpad in Lenovo Ideapad Y530 is not being detected in the correct way.
On kernel 3.5 xinput list shows:
      Code:

 
⎡ Virtual core pointer                       id=2   [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                 id=4   [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                 id=11   [slave  pointer  (2)]
⎜   ↳ MCE IR Keyboard/Mouse (ite-cir)            id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                      id=3   [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                id=5   [slave  keyboard (3)]
    ↳ Power Button                               id=6   [slave  keyboard (3)]
    ↳ Video Bus                                  id=7   [slave  keyboard (3)]
    ↳ Sleep Button                               id=8   [slave  keyboard (3)]
    ↳ Asus Laptop extra buttons                  id=9   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard               id=10   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                      id=12   [slave  keyboard (3)]
    ↳ ITE8708 CIR transceiver                    id=14   [slave  keyboard (3)]

but on 3.6:
      Code:

⎡ Virtual core pointer                       id=2   [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                 id=4   [slave  pointer  (2)]
⎜   ↳ ImPS/2 Synaptics TouchPad                  id=11   [slave  pointer  (2)]
⎜   ↳ MCE IR Keyboard/Mouse (ite-cir)            id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                      id=3   [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                id=5   [slave  keyboard (3)]
    ↳ Power Button                               id=6   [slave  keyboard (3)]
    ↳ Video Bus                                  id=7   [slave  keyboard (3)]
    ↳ Sleep Button                               id=8   [slave  keyboard (3)]
    ↳ Asus Laptop extra buttons                  id=9   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard               id=10   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                      id=12   [slave  keyboard (3)]
    ↳ ITE8708 CIR transceiver                    id=14   [slave  keyboard (3)]

The result is that synclient -l complains that
      Code:
Couldn't find synaptics properties. No synaptics driver loaded?

As a result I can't get to work any of my settings for touchpad :/

Please try it without /etc/X11/xorg.conf.d/20-synaptics.conf and synclient, is it dead alltogether, does it behave like a normal mouse, what about tapping and scrolling - what does /var/log/Xorg.0.log say?

My own tests, however with much older hardware, have been successful with SynPS/2 Synaptics TouchPad and AlpsPS/2 ALPS GlidePoint.

Basic functions such as left/right button, basic scrolling work.

I'll try without them (synclient -l was only used to check current settings), however I would be grateful if You would point me how to make tapping acting like a 3rd mouse button (middle click) in a up to date way? Not to mention the fact that it's a little strange for me that these work with previous kernel (even today, I have one still installed).

So far I have yet another strange fact, if I do rmmod psmouse and after that do insmod /lib/modules/3.6-0.slh.1-aptosid-amd64/kernel/drivers/input/mouse/psmouse.ko, then xinput list, again shows it as SynPS/2 Synaptics TouchPad and my config works ok.

That would mean the touchpad gets correctly detected as a touchpad, the mouse emulation fallback (predominantly supported by alps devices) wouldn't support scrolling at all (just mousepointer && left click), suggesting 'just' a configuration issue. Unfortunately multi-touch is not supported by the touchpads I have access to, so I can't help a lot with specifics in this regard.

The module loading differences are a bit weird, but for that we'd need further logging output.

Some update,
without the .conf file in /etc/X11/xorg.conf.d, after first reboot xinput showed SynPS/2 Synaptics TouchPad.
After second reboot touchpad again was shown as ImPS/2 Synaptics TouchPad - however I managed to spot a suspicious entry in the dmesg output:
      Code:
[    7.532126] psmouse serio4: synaptics: Unable to query device.

Complete dmesg output: http://wklej.org/hash/31809669ca/

If I can provide any more logs, just please tell me which.

As far as the touchpad goes, I would just like to have an option to configure tapping the touchpad as a "middle" mouse button click, the multitouch options such as double finger scrolling are not really needed (and they seem to come and go depending on the version o xserver packages and/or kernel combined with my hardware).

I use gpointing-device-settings not for a touchpad but for an optical mouse, but according to its man page it does too. It is a relative of GTK family, not a QT one.

Best regards.
