RHEL 6 Configure Synaptics TouchPad

Alpo · 07-27-2011, 06:20 PM

All:

I'm looking to install drivers for my Synaptics touchpad. I have xorg-x11-drv-synaptics-1.2.1-5.el (x86_64) installed, but I don't know how I can get this little guy to work. Thanks!

I found this link useful myself:

rkski -

Thanks. I've read through that a few times, to no avail...

Code:

$ synclient -m 100
Can't access shared memory area. SHMConfig disabled?
Couldn't find synaptics properties. No synaptics driver loaded?

I don't have an xorg.conf file in my /etc/X11/ directory. Should I create one? I'm very unfamiliar with this system. Any help would be greatly appreciated.

As for a more specific question, that tutorial states, "After installation of xf86-input-synaptics, a default configuration file is located at /etc/X11/xorg.conf.d/10-synaptics.conf."

Since I'm actually installing xorg-x11-drv-synaptics-1.2.1.el6 (x86_64), would the location of that file be different?

Just create that file if it is not there. Maybe this post will help you.

Alpo · 07-27-2011, 10:27 PM

Haha. I guess avoiding GUIs all together would solve the problem.

Where can I go to get good documentation on how the X-windows system works (i.e. How on earth can I just create that file/directory and know that X-windows will execute that code?). I checked out www.x.org, but there's so much info, it's difficult for a newbie to keep it straight. Where should I start?

The location will be the same, just create that file and look at TobiSGD's example in the link he gave for what to put in it, then restart X.

For documentation on X look at www.tldp.org for a start.

rkski

Thanks for all the info. I'll give that solution a shot tonight and let you know.

Alpo · 07-28-2011, 05:12 PM

OK. So, I created and edited /etc/X11/xorg.conf.d/10-synaptics, and it now reads...

Code:

Section "InputClass"
        Identifier "touchpad"
        Driver "synaptics"
        MatchDevicePath "/dev/input/event*"
        MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "0"
        Option "TapButton3" "0"
        Option "VertEdgeScroll" "1"
        Option "HorizEdgeScroll" "1"
        Option "MinSpeed" "1.1"
        Option "MaxSpeed" "1.9"
EndSection

However, I'm still not getting any scrolling, so it seems the driver may not have loaded. How can I check?

Here's another problem:

Code:

[Alpo@alpo-computer ~]$ synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

TobiSGD · 07-28-2011, 05:18 PM

Did you restart the Xserver, so that it actually reads that file?

To check if it reads the file and loads the driver do

Code:

grep -i synaptics /var/log/Xorg.0.log

Alpo · 07-28-2011, 07:52 PM

Code:

$ grep -i synaptics /var/log/Xorg.0.log

Your thoughts?

Is that after a restart? Looks very different from what I get and I can't see any mentioning of the options set in that file.

Here is how mine looks:

Yup, definitely after a restart.

Also, on startup and shutdown there's a small message in the top left of the screen that says "Unable to query Synaptics hardware." What does that mean exactly and how does it fit into the big picture?

TobiSGD · 07-28-2011, 08:22 PM

Sorry, but I don't know any further. May be now is the time to contact the Red Hat-support.
