[solved] Synaptics driver scrolling issues

synthead · 2008-04-30 01:08:13

My touchpad is acting up. I was changing some settings, and as far as I can tell, they're set right, but the driver isn't working the way I want it to. If I'm in the scroll area of my touchpad, the cursor moves up and down on the screen in a perfectly vertical fashion, but nothing scrolls. Is there anything obviously wrong with my xorg.conf?

Try including these in Section "InputDevice":

Option  "HorizEdgeScroll" "1"
Option  "VertEdgeScroll" "1"
Option  "VertScrollDelta"   "20"
Option  "HorizScrollDelta"   "20"

The first two enable horizontal and vertical edge scrolling, and the second two control the speed of this scrolling. From memory, smaller numbers equals faster scrolling.

man synaptics

for all the info you need.

Thank you for your reply I flipped through the man page and threw in what you suggested, but for some reason, it only scrolls horizontally no matter what I do to xorg.conf (so far). I even have no entry to scroll in this direction ... this is my xorg.conf right now

This might sound stupid, but you have enabled scrolling in your DE?
eg Gnome: system, touchpad etc....
(similar thing happened to me once and I had scrolling disabled for some reason).

synthead · 2008-04-30 06:49:45

I'm using XFCE and there isn't an entry for scrolling from what I can see.

floke · 2008-04-30 10:30:22

Ah! Try uncommenting the line with Option "SHMConfig" "true" - I think you need this for scrolling

synthead · 2008-05-01 03:28:19

SHMConfig is an option if you want to use gsynaptics. I enabled it and started gsynaptics, checked "vertical scrolling", and it still doesn't scroll

synthead · 2008-05-01 17:19:10

The really weird part is that horizontal scrolling works, but I don't want it to be enabled and I can't turn it off. Horizontal scrolling is commented out in xorg.conf.

floke · 2008-05-01 19:23:45

Sorry, I'm all out of ideas - I actually had a similar problem yesterday.
You can see my bodged solution here:
http://bbs.archlinux.org/viewtopic.php?id=47933

synthead · 2008-05-02 20:23:01

If I change "RightEdge" to something about 5500, the scrolling works. BUT! It's weird. If I try to use it the first time X starts, it doesn't. If I really cram my finger over to the side of the touchpad, it works! And the scrolling area comes to life. But now the right half of the touchpad is a scroll riegon. Weird ...

lambchops468 · 2008-05-02 22:08:41

what about using

Option    "SHMConfig"    "true"

and then running

synclient -m 50

to see where the actual boundaries of your touchpad are?

Sounds to me like your boundaries are off

<next part straight from man >
the right edge wil determine the **left** boundary of the vertical scrolling area.

       
             |             |
             | LeftEdge    | RightEdge
       +-----+-------------+---+ Physical top edge
       | 1   |      2      | 3 |
       +-----+-------------+---+ TopEdge
       |     |             |   |
       | 4   |      5      | 6 |
       |     |             |   |
       +-----+-------------+---+ BottomEdge
       | 7   |      8      | 9 |
       +-----+-------------+---+ Physical bottom edge
       |Physical left edge     | Physical right edge

the vertical scrolling area between the right edge and physical right edge
the horizontal scrolling area between bottom edge and physical bottom edge.

Man, I love you guys ...

I did the synclient examination and it turns out that my touchpad's x-axis jumps from somewhere about 5950 to 8176 when crossing over the little scrolling bump. Probably a hardware or firmware thing, but I set my RightEdge value to 5900 and my scrolling area works just absolutely perfect. Setting it to anything in this "dead zone" really confused the synaptics driver. Pretty bizzare, but it works like it's supposed to now. Boy I'm glad that's over with, couldn't have done it without all of the help!

I'll be lurking around the forums to do my part in return!

synthead · 2008-05-09 19:29:38

I just fixed another laptop's scrolling issues with synclient. Just wanted to mention it

gils0040 · 2008-07-07 13:46:03

Just wanted to say thanks for this thread, and thanks for posting the solution synthead. I have a synaptics touchpad in a gateway mt3423 and have had this problem for a while. The scroll pad wouldn't work when i first started x but if i kept jamming on it eventually it would. Setting the right edge to 5900 worked perfectly. Thanks again!
