A Sony Vaio PCG-K33 with a synaptics touchpad. It is working only the ordinary function (as mouse). I am trying to startup the advanced functions with out succes.

I have emerge synaptics and ksynaptics.
Them adjusting the parameter in xorg.conf or the touchpad at control center result nothing.

and no more ideas?!?!?!?

what doesn't it do, the sliders at the the sides and bottom and the right/left/middle click on the pad?
On my touchpad, all I did was add the driver in xorg.conf and it works perfectly. All the other lines that the wiki says to add I left out. Maybe try commenting out all those lines and seee what happens, it seems to have found the edges and such for me...

I disable the PS/2Mouse and remain working (before not), and coment all the slider options and SHMconfig. It start working with the default configuration. Than putting the README.alps.gz configuration (only) I get a better result, but I must not have SHMConfig on.

Then the synaptics driver now is working good.

But the KDE interfece (ksynaptic) doesn't adjust any parameter. Something else I forget?

I think you have done most of everything I did, though I never realy used the ksynaptic interface to change anything. I generally find that KDE apps like ksynaptic and knetwork and the like don't actually do anything. Your best bet is probably trying to alter your xorg.conf as appropriate to achieve the results you want from the touchpad.
