Hello, to all.
I upgraded recently from xorg-server-1.7.x to 1.9.x. version. Before that I had my input device configured in infamous HAL fdi files. That was replaced by /etc/X11/xorg.conf.d folder containing a file to each input device: keyboard and synaptics touchpad.
After that my touchpad slowed down significantly, altough I kept same numbers for synaptics parameters. Here is my synaptics.conf file:
Code:
Section "InputClass"

Identifier "Touchpad0"
Driver "synaptics"
Option "SendCoreEvents"
Option "SHMConfig" "true"
Option "LeftEdge" "1700"
Option "RightEdge" "5300"
Option "TopEdge" "1700"
Option "BottomEdge" "4200"
Option "FingerLow" "25"
Option "FingerHigh" "30"
Option "MaxTapTime" "180"
Option "MaxTapMove" "180"
Option "VertEdgeScroll" "true"
Option "MinSpeed" "0.35"
Option "MaxSpeed" "0.90"
Option "AccelFactor" "0.01"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"

MatchDevicePath "/dev/input/event*"
MatchIsTouchpad "on"
EndSection


I notice error messages in my /var/log/Xorg.0.log file.

Code:
grep EE /var/log/Xorg.0.log
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[    60.591] (II) Loading extension MIT-SCREEN-SAVER
[    62.041] (EE) SynPS/2 Synaptics TouchPad no synaptics event device found
[    62.061] (EE) Query no Synaptics: 6003C8
[    62.061] (EE) SynPS/2 Synaptics TouchPad Unable to query/initialize Synaptics hardware.
[    62.061] (EE) PreInit failed for input device "SynPS/2 Synaptics TouchPad"

Actually running "synclient -l" I can see that my settings are there, i. e. scrolling works quite ok, but cursor movement speed is much slower than it was before.

Has anyone experienced such synaptics touchpad misbehaviour?

I did not have any luck with the /etc/X11/xorg.conf.d directory.
Try the /usr/share/xorg.conf.d directory instead.

Oh, and I assume you have re-emerged the xf86-input-synaptics and the xf86-input-evdev packages.

You mean no luck with synaptics touchpad? My keyboard settings are fine, working from "/etc/X11/xorg.conf.d" folder. I did re-emerged all that was in "qlist -I -C x11-drivers/".
If switching to /usr/share/xorg.conf.d is more effective for setting up synaptics touch pad I could try that.

Drop that SHMConfig line, IIRC it's not needed at least since xorg-server 1.8.

I have just also upgraded to 1.9 from 1.7, and what I feel is that the corner coasting works slower (and less responsively) that it used to. The config numbers are kept all the same and are in xorg.conf (never used HAL). Perhaps the changes in synaptics driver are the cause.

I had the same issue. Downgrading xf86-input-synaptics from version 1.3 to 1.2 fixed the problem. I have Xorg 1.9 and it works fine with the older driver. IMHO the new one is buggy.

By the way, the directory to use with a custom X configuration *is* /etc/X11/xorg.conf.d/ . The directory in /usr/share provides only the default settings when no custom config exists so it contains very little so as to work on most machines.

Just found forum topic with same issue: https://forums.gentoo.org/viewtopic-t-847177-start-0.html, which led to BugZilla page https://bugs.gentoo.org/show_bug.cgi?id=345981, where it was recommended to add a line
Code:
MatchDevicePath "/dev/input/event*

to file "/usr/share/X11/xorg.conf.d/50-synaptics.conf". Just did that and errors disappeared, but cursor movement is still slower then it used to be. However, I attribute this to driver change since errors frmo Xorg.o.log file disappeared.

Well, downgrading fixes the slow motion pointer. In my case, not only was the pointer slow but also erratic: random scrolls, random moves, random sensibility to pressure...

Hurray! Version 1.2 is no longer in portage and I have been crazy enough to upgrade a few days ago... No [need to] say I'm screwed.

Hi, ALL,
I have the same problem as described here with 1.3.0.
I just sync'ed and I see that there is version 1.4.0 of the xf86-input-synaptics.

Is this issue with slowing fixed there?

Thank you.

Ah... had forgotten this thread! Yes the issue is fixed, at least for me. I've had to create an Xorg input configuration file for my touchpad with these settings:
/etc/X11/xorg.conf.d/20-input-touchpad.conf:
# Xorg configuration: mouse
Section "InputClass"
        Identifier      "Touchpad0"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver          "synaptics"
        Option          "TapButton1" "1"
        Option          "VertEdgeScroll" "true"
        Option          "HorizEdgeScroll" "true"
        Option          "RTCornerButton" "3"
        Option          "RBCornerButton" "2"
        Option          "MaxTapMove" "131"
        Option          "EmulateTwoFingerMinZ" "24"
        option          "EmulateTwoFingerMinW" "8"
        Option          "VertTwoFingerScroll" "on"
EndSection

Vertical scrolling with two fingers now works again! This should help.

Hi,
Yes, I upgraded and the slowness is gone.
Moreover, it turns on my wired interface somehow. :roll:

Thank you.
