Touchpad Does Not Scroll

[Chaos]

I'm running LMDE xfce, and I cannot scroll vertically or horizontally with my touchpad. I don't use a mouse, so feelsbadman.jpg
Anyone know how to adjust touchpad settings on XFCE?

Type of pad? Chipset of pad? any further reference would be helpful.

To be quite honest, I too have had these issues over the years and figured them out by knowing what typepad or hardware chip was driving known issue. In other words, this is the norm. If you have something not working, the best you can do is reference the actual chip and manufacturer against the linux kernel ref. You can either load a hardware module, or compile the kernel for specific reference to such hardware.

While most of the time in Linux these days it "just works" (Oh how nice), I compile and work still to date with specific hardware components that do not allow for those specific drivers to be loaded. It's a toss up. But not every driver known to man is supported, if a certain requirement is needed, you will need to find the driver that supports that hardware.

Linux is great... it provides for a majority... but if it doesn't work, you make it work. The power of linux is the person whom operates it. If you can provide the actual chip or set of chips, it can be looked up to see what type of linux support is available per manufacturer.

Interesting.
I was starting to have issues with my touchpad scrolling when I was running mint KDE too. That was just a few days ago.
Maybe this has something to do with running on a reallllllly overworked and aging computer.

make sure you set the touchpad configuration to enable scrollling, it's on mouse section on Control center

Yes... there have been problems with these touchpads..

Please paste the contents of this file so that we can help you:

/usr/share/X11/xorg.conf.d/50-synaptics.conf

[Chaos]

This is my /usr/share/X11/xorg.conf.d/50-synaptics.conf:

Code: Select all

# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of
#   Option "OptionName" "value"
#
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
#       MatchDevicePath "/dev/input/event*"
EndSection

make sure you set the touchpad configuration to enable scrollling, it's on mouse section on Control center

xfce doesn't have this option

[dritzominous]

Code: Select all

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"

change this ^

To this v

Code: Select all

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "TapButton1" "1"    # tap to click

Is everything working now?

@dritzominous
It activates the tap on the touchpad, but does not activate scrolling.

[dritzominous]

Code: Select all

Option "VertEdgeScroll" "1"

^ try adding that in there.

If you could, please explain all of the features of your touchpad.

Ex. Does a 2 finger tap activate the middle click? How about right click? Is it a 3 finger tap? (It is on mine)

I tried this fix on my new laptop "Lenovo z575" and it had no effect on my inability to scroll... All other mouse functions work perfectly as they had before. In my case it must be a driver problem. I am using linux mint 9 kde and the location of the config file is different.. /usr/lib/X11/xorg.conf.d/10-synaptics.conf.
How do i find out what type of pad i have?

Same problem here. Running latest LMDE XFCE. I was so used to scroll with the touchpad >.> My laptop is a Toshiba Satellite L650 C13.

Thank you!

Those 2 additional lines fixed the touchpad issues on my Acer Netbook. It's an AO532h with Synaptics pad. It has multi-touch 2-finger scrolling, which did work, but it also has a separate strip on the side for vertical scroll, and that did not work. Also tap to click wasn't working. Now tap works, and my scroll strip as well. I really love that separate scroll strip. There's no confusion between moving the pointer and scrolling.

Aloha, Tim

PS: LMDE Xfce is what I needed fixed. It works out of the box in 13.

[Lolo Uila]

Okay, this is odd. For some reason the tap-click no longer works. It worked for a while after editing the file, but now it doesn't. I checked the file, and the edits are still there. I even tried deleting the edits and applying them again. No tap-click

Anyone got any ideas of why it stopped working, and how to fix it?

Note the the tap function still works in Mint-13, and even Crunchbang (which is also based on Debian testing).

If you run this command from a terminal does it turn it back on?

Code: Select all

synclient tapbutton1=1

[Lolo Uila]

Yes, it does. Thanks. That helped me figure out what was wrong. It was an ID-Ten-T error.

Chaos,
If you execute the following command in a Terminal Window you can see all the Synaptics Touchpad command parameters that are available:

Code: Select all

synclient -l


such as:

If you're interested in another software package to control your settings via a GUI, there is "gpointing-device-settings" in the repo's. You can extract the
attached zip and drag the Desktop Icon to your lower left menu, making it easy to access gpointing-device-settings.

There is also a script to allow you to modify what you need on startup, as needed/if needed.
