how to configure touchpad mouse

Ay-Karamba! · 10-08-2005, 08:57 PM

Hi,
I'm running FC4 on my laptop, and I couldn't find a way to configure the touchpad pointing device. The problem is the bottom horizontal edge of the touchpad correspond to 'back' and 'forward' in firefox, and I keep pressing them accidentally. I've tried to search some threads and howtos, but I couldn't find anything much.

I've also tried to figure this out. The tapping on the touchpad is so sensitive it's almost useless. I've hunted on google many times for this, but to no avail....

Xorg seems to have touchpad support built in - unlike XFree86 in Debian Testing a while ago. Anyway, I was able to tweak all necessary touchpad parameters by simply editing the /etc/X11/XF86Config-4 (your xorg.conf).

Xorg documentation should include documentation for the touchpad driver. All available options should be listed there. You might also try to googlelinux with "synaptics xorg" to see what happens. At least in XFree "synaptics" was the name of the driver used with touchpads.

basileus, Could you post your XF86Config-4 file, so that we can see how you tweaked your touchpad? I too have this problem...

Hi,

I have a synaptics touchpad on an my laptop. Before I had this problem of sensitivity to high, now it disappeared. Maybe due to my configuration changing or to a new drivers.
I have these *packages* on my Debian with kernel 2.6.12.3 :
ksynapitcs for configuring it (0.2.0-1) ,
xfree86-common (4.3.0.dfsg.1-14sarge1)
i don't have the standalone synaptic driver installed, nor xfree86-driver-synpatics.

dmesg | grep Synaptics gives
Synaptics Touchpad, model: 1, fw : 5.9 , id:0x1b6eb1 , caps : 0xa84793/0x100000
serio : Synaptics pass-through port at isa0060/serio4/input0
input: SynPS/2 Synaptics Touchpad on isa0060/serio4

In Control Center :
Peripherals->Touch Pad :
Sensitivity : Position 3 out of 5 (middle)
Scrolling : Horizontal : 4/6 , same for vertical

And it works as expected.

Can you please explain where to find this xorg.conf, and how to edit it? I've tried to google "synaptics xorg", but what came out is mostly about touchpad driver for xorg, which I don't think I need, because the touchpad itself is already working. Thanks

Is there anything like that for Fedora with Gnome desk env?

Nd4Spd · 10-12-2005, 09:41 AM

xorg.conf is located: /etc/X11/xorg.conf

You can edit it from the command line using your favorite editor (vi, emacs, pico, nano)

Thanks for letting us know about gsynaptics, so I've tried to compile this app, but it went error when I tried to do ./configure. Here's what I got

configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

And this 'config.log' is a whole lot of rubbish, I couldn't even understand a single line of it so pls tell me if posting it here will be useful.

And in addition to it, I also tried to configure xorg.conf, but I couldn't find any settings / options related to touchpad. The closest thing I found is this

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "yes"
EndSection

Do we have to add our own "Option" or something??

Thanks

Try this :

rpm -qa gcc-c++
Then retry ./configure

Try also the config file from Nd4Spd

Thanks for helping, I've tried rpm -qa gcc-c++, but after3-4 seconds it returns nothing. Then when I tried ./configure again, same error still pop up. And the config file didn't really help, the touchpad is not working at all.

Hi

my mistake
If I remember (I don't use rpm now) , the options -qa query if the package exists.
And if nothing was displayed, it means the package is not installed :-)

So
$rpm -hUv <thing_to_install> to install something.
$man rpm is really something you should look at

then you should be able to go further in the compilation. But this tool only tweaks a little bit the touchpad. It doesn't install anything
Now you say your touchpad doesn't work at all? Even with your old config file?

Could you give the output of this to see if you really have the driver installed:
$dmesg | grep Synapt

Can somebody guide me where to find documentation on the synaptics driver. What do all these "options" do? What are the other possibilities? I have been searching on the net and have found a lot of posts giving their XFConfig-4 files or the parts that deal with the touchpad. But I do not find any documentation on what are these options. I have tried a few of these but they do not give me the kind of performance that I, for example, get on Windows XP. The touchpad either becomes too sensitive (it keeps hopping as I type because my had touches the oversensitive touchpad by mistake) or it turns off tapping altogether.

Can someone guide please?
