[solved]Touchpad (Elantech?) fails to work with Kernel 2.6.35

Hi,
after updateing to kernel26 2.6.35, the touchpad on my Asus X5DIJ stopped working correctly. The cursor now moves to the position I touch the touchpad, instead of moving relatively to my finger-movement.
It used to be recognized by X like this:

[ 16070.972] (II) config/udev: Adding input device ImPS/2 Logitech Wheel Mouse (/dev/input/event7)
[ 16070.972] (**) ImPS/2 Logitech Wheel Mouse: Applying InputClass "evdev pointer catchall"

but now it's:

Installing xf86-input-synaptics enabled the correct pointer-behaviour, but two-finger-scrolling, right- and middle-clicking still doesn't work.

Any ideas?

Re: [solved]Touchpad (Elantech?) fails to work with Kernel 2.6.35

Are you using GNOME?

Re: [solved]Touchpad (Elantech?) fails to work with Kernel 2.6.35

Yes, I'm using Gnome on x86, testing disabled, stock 2.6.35 kernel, empty xorg.conf, xorg.conf.d/10-synaptics contains the lines from the log

Option "EmulateTwoFingerMinZ" "40"
Option "EmulateTwoFingerMinW" "5"
Option "VertScrollDelta" "100"
Option "HorizScrollDelta" "100"

Re: [solved]Touchpad (Elantech?) fails to work with Kernel 2.6.35

The thing is, since 2.6.35, the touchpad is now properly recognized as a Synaptics-type touchpad. When the Synaptics X driver is loaded, GNOME takes control of the touchpad and apply its own settings, bypassing Xorg configuration (an awkward move since the user expects his touchpad to behave as xorg.conf describes it).

So, you have two solutions :

• tell GNOME you don't want it to screw with your touchpad (and your mouses in general):

  gconftool-2 --type boolean --set /apps/gnome_settings_daemon/plugins/mouse/active false

  and restart X

• configure your touchpad directly with GNOME (System->Preferences->Mouse->Touchpad), but there are far less options...

Re: [solved]Touchpad (Elantech?) fails to work with Kernel 2.6.35

Apparently I should first try to do it "windows style" instead of messing around with config files. The touchpad section shows up >2.6.34 and works as it should.

To make things worse, it's even mentioned in the wiki's "touchpad" section...but good thing it's finally recognized as a touchpad instead of a PS/2 mouse
