I have an Acer Aspire 5740 with a synaptics touchpad. I have tried using the ksynaptics program as well as the touchpad settings under System Settings >> Computer Administration. My touchpad works, but it is driving me crazy with how sensitive the tap to click feature is. I want to disable it altogether so I can actually work on my computer. When I go to the touchpad section in System Settings >> Computer Administration >> Keyboard & Mouse, the tab says “Warning: Touchpad configuration is not supported on this system. The synaptics driver is either not loaded or too old. Refer to doumentation for information about the required driver version.” Can someone please help me disable this tap to click? Your help will be greatly appreciated since this stupid setting is making my life miserable. Thank you.
I found a Ubuntu user that claimed this works in setting up the touchpad. Perhaps this will give you an avenue to do what you want.
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8
If this helps in any way, I could write a script file with these commands that runs each time your restart openSUSE.
Thank You,
I tried running the commands you mentioned, but I get a command line error saying “unable to find device SynPS/2 Synaptics TouchPad”. Do you think that the module would not be loading for some reason? Thanks again for the help. I am willing to try anything.
I guess I would run YaST / Hardware / Hardware Information and find out just what it is called. If it works at all, it has to have a name, if it is not SynPS/2 Synaptics TouchPad, then what is it?
Thank You,
Under Yast >> Hardware Information, the “Mouse” is listed as “ImPS/2 Generic Wheel Mouse” which seems to indicate it does not recognize this as a synaptics touchpad at all. Can I still configure this as a generic wheel mouse?
It is very hard to provide help on a hardware device one does not have or has ever used before. None the less, I would start with YaST / Software Management and search on Synaptics. I found two files that started with gsynaptics and I would load both. It looks like the files you can run are called /usr/bin/gsynaptics-init & /usr/bin/gsynaptics. You could try running these one at a time from the menu run command (in KDE) and see if this does anything for you. You can also look at KDE’s Personnel Settings / Keyboard & Mouse as another place to try. I have never had much luck doing anything with a mouse in YaST / Hardware before.
Thank You,
It is my understanding that using OpenSuSE 11.3, there is no xorg.conf file. My /etc/X11/ directory does not have an xorg.conf file. It is also my understanding that the later distros instead use /etc/X11/xorg.conf.d/ directory which contains several setup files for devices. In the /etc/X11/xorg.conf.d directory there is a file named 20-synaptics.conf. Unfortunately, this file does not ever seem to load properly since my device is listed as “ImPS/2 Generic Wheel Mouse”. My /etc/X11/xorg.conf.d/20-synaptics.conf reads as follows:
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "HorizScrollDelta" "99" # enable horizontal scrolling
Option "VertTwoFingerScroll" "True" # enable vertical two-finger scrolling
Option "VertScrollDelta" "99"
Option "TapButton1" "1" # 1-finger tap = left mouse click
Option "TapButton2" "3" # 2-finger tap = right mouse click
EndSection
My /var/log/Xorg.0.log reads as follows from my most recent bootup:

There is no mention of synaptics at all in the xorg log file, only the generic wheel mouse.
Can someone please help me figure out how to get this working. It is so frustrating that it is about to send me back to Windows, which trust me, I don’t want to do. I am using an Acer Aspire 5740-6491 which uses an ALPS touchpad. My understanding is that the synaptics driver should work just fine with an ALPS touchpad. Also, I cannot use gsynaptics as I get an error reading:
“GSynaptics couldn’t initialize.
You have to set ‘SHMConfig’ ‘true’ in xorg.conf or XF86Config to use GSynaptics”. Again, this distro does not use xorg.conf file. Additionally, I cannot use the “Configure Desktop” “TouchPad” in KDE which I believe uses ksynaptics because I get an error reading “Warning: Touchpad configuration is not supported on this system. The synaptics driver is either not loaded or too old. Refer to the documentation for information about the required driver version.”
I have also tried adding the grub boot option “i8042 nopnp=1” as some forums said to try but this did not help either. This frustration is the very reason I typically do not recommend Linux to others at this point. Driver support is poor at best and nobody likes spending days trying to get a touchpad to work. Anyhow, please help if you have any further information. Thank you.
I’m having the same problem with a Lenovo G550.
In my searching I came across a post saying that gsynaptics is deprecated, so that wouldn’t seem to be the soluton.
I also came across a post saying this is a bug in the current Linux kernel and there’s nothing we can do to get around it. I’m not sure that’s true, but I haven’t found anything newerr.
FWIW, touchpad scrolling on these laptops will work with older versions (such as Ubuntu 9.04).
That’s about all I know so far. (I just created my own thread on this question an hour or so ago, and you can find the link to the bug there.)
I think you can still create a Xorg.conf somehow and that will override wherever you have it specified. I too am having this problem on HP Mini 311, and would like to have the touchpad recognized properly.
The OP did not specify KDE version. I cannot speak for KDE 4.4, KDE 4.5.5, the touchpad options are found in
http://thumbnails17.imagebam.com/11445/cf958b114447177.jpg](http://www.imagebam.com/image/cf958b114447177)
For KDE 4.6 RC2, the touchpad options are found in
http://thumbnails36.imagebam.com/11445/245df4114447167.jpg](http://www.imagebam.com/image/245df4114447167)
Under 4.5, the touchpad option seemed to wander among categories. The last update seems to have dropped it into Lost and Found.
