Ubuntu 10.10 two-finger scrolling doesn't work

[pandacat17]

Hey everyone!
(I really hope this was the right category...it seemed the most appropriate)
I just installed ubuntu 10.10 on my thinkpad t410 and so far I'm loving it. The only (fixable) downside for me is that I cannot enable two-finger scrolling in the preferences. After spending all day trying various solutions on the internet and these forums, I decided to post asking for help.


Thanks!

Have you tried installing "pointing devices" and configure it there?

Try using synclient from a terminal.

synclient -l

Will show current options, 1 is set & 0 not set

man synclient

To see synclient manual.

Synclient set the options used by synaptics.

man synaptics

To see synaptics manual with list of all options.

Yes, I have. Everything is enabled inside of that box but I still cant use two-finger scrolling.

I've tried using the synclient commands in terminal a number of times...but I don't think I quite understand what to do. When I enable (put to 1) VertTwoFingerScroll nothing is changed. Are there other options I need to be changing?

Hey Guys!

creating the file /usr/share/X11/xorg.conf.d/50-twofingerscroll.conf with the following content:

Section "InputClass"
	Identifier	"Zwei-Finger-Bildlauf für Touchpads einschalten"
	MatchProduct	"SynPS/2 Synaptics TouchPad"
	MatchDevicePath	"/dev/input/event*"
	Option		"VertTwoFingerScroll"	"on"
	Option		"EmulateTwoFingerMinW"	"8"
	Option		"EmulateTwoFingerMinZ"	"40"
EndSection

And setting desktop->gnome->peripherals->touchpad->scroll_method to 2 in gconf-editor did the magic for me!

Now I have Two-Finger-Scrolling with Ubuntu 10.10 on my Thinkpad T410!

WHY??? WHY???

Why do we need to follow all this steps that sometimes we don't understand...?

Why is not enough to setup VertTwoFingerScroll to 1 in synclient...?

Why is not enough to modify gconf-editor variable /desktop/gnome/peripherals/touchpad/scroll_method to 2....?

Why do we need to create this file /usr/share/X11/xorg.conf.d/50-twofingerscroll.conf...?

now I end up with a buggiest 2 finger scrolling that works randomly and 90% in the inverse direction...!

Hey! now is working... this is what I did:

1. Install "Pointing Devices"

2. Open System / Preferences / Pointing Devices and disable Vertical and Horizontal Scrolling.

3. Open a terminal (ctrl + alt + t) and execute this commands:

synclient HorizTwoFingerScroll=1
synclient VertTwoFingerScroll=1
synclient EmulateTwoFingerMinZ=40 
synclient EmulateTwoFingerMinW=8

4.Open a terminal (ctrl + alt + t) and execute this commands:

gconf-editor

5. Navigate and find this key: /desktop/gnome/peripherals/touchpad/scroll_method

6. Assign the value '2'

7.Open a terminal (ctrl + alt + t) and execute this commands:

cat /usr/share/X11/xorg.conf.d/50-synaptics.conf

8. Copy the Identifier name, in my case, it was "Touchpad catchall"

Identifier "touchpad catchall"

9. Execute this command, as a Super User.

sudo nano /usr/share/X11/xorg.conf.d/50-twofingerscroll.conf

10. Write this, making sure to put your Identifier.

Section "InputClass"
        Identifier      "touchpad catchall"
        MatchProduct    "SynPS/2 Synaptics TouchPad"
        MatchDevicePath "/dev/input/event*"
        Option          "VertTwoFingerScroll"   "on"
        Option          "EmulateTwoFingerMinW"  "8"
        Option          "EmulateTwoFingerMinZ"  "40"
EndSection

And that's all!

Thank you ptosiani for the great post!

I don't have a /usr/share/X11/xorg.conf.d

I do however have a /usr/lib/X11/xorg.conf.d and I tried to do the instructions to no avail.

I'm using ATI drivers with synaptics touchpad. Any other info you need?
