T440s Clickpad configuration

fabiopicchi · 2015-01-06 15:24:45

Hi! I have just bought a new laptop and I am strugling to find a satisfying configuration for my clickpad. I have seen this suggested configuration in the arch wiki:

http://rscircus.org/post/72978821261/t4 … feels-good

Also, I read the synaptics manual and the arch wiki page. My problem is that I want to reduce the soft buttons area, where mouse move isn't detected. However, I can only increase it, any value lower that 2200 is stuck at about 40% of the touchpad height. I have tried using evtest to get the minimum y coordinate and I got about 1300. My configuration is the following:

# Custom xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# Additional options may be added in the form of
# Option "OptionName" "value"
#
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event7"

# Helps to reduce mouse cursor "jumpiness"
Option "HorizHysteresis" "30"
Option "VertHysteresis" "30"

# Settings reported to work well on an X1 Carbon
Option "FingerLow" "40"
Option "FingerHigh" "45"
Option "MinSpeed" "1"
Option "MaxSpeed" "1.75"
Option "AccelFactor" "0.04"

Option "SoftButtonAreas" "60% 0 0 1500 40% 60% 0 1500"
Option "AreaTopEdge" "1500"

# Disable edge scrolling, I prefer two-finger scroll instead
Option "VertEdgeScroll" "0"

# Disable tap and drag gesture
Option "TapAndDragGesture" "0"

Option "PalmDetect" "1"

Option "TapButton1" "1"
Option "TapButton2" "3"
Option "TapButton3" "2"

Option "ClickButton1" "1"
Option "ClickButton2" "3"
Option "ClickButton3" "2"
EndSection

Has anyone faced this kind of problem? Disabling the Clickpad option makes the whole touchpad area move the mouse, but I lose the ability to move the mouse while clicking.

I have same problem and i opened a thread here (Laptop issues). So if there is a solution let me know

fabiopicchi · 2015-02-06 13:34:08

Still haven't found a solution. I am hoping that this kernel update coming soon somehow solves this problem =/

Boogie · 2015-02-11 10:26:41

Kernel 3.19 doesn't solve this I guess its a xf86-input-synaptics problem? Sooner than later, libinput will probably take over X11 input so synaptics will be obsolete.

Boogie · 2015-02-11 11:35:47

Take a look at Peter Hutterer's blog hes the X input hacker and also maintainer of libinput (Which is soon to come, and in staging repos at the moment).. But maybe we should report our messurements to him, in that case we might have a fix for kernel 3.20.

Fellow T440s user here. I'm experiencing similar issues. I also cannot decrease the height of my SoftButtonArea or AreaTopEdge. I'm also experiencing issues resizing the middle & right-click regions via SoftButtonArea. I've been using:

Option "SoftButtonAreas" "60% 100% 0 1200 40% 60% 0 1200"
Option "AreaTopEdge" "1200"

That doesn't appear to work... It's still starting the right button at around 50%. As an experiment, I tried the following:

Option "SoftButtonAreas" "25% 100% 0 1200 0 0 0 0"

That had the desired result: the right button started at about 25% of the touchpad. I then tried:

Option "SoftButtonAreas" "90% 100% 0 1200 0 0 0 0"

This did not work. This behaved exactly the same way as the first SoftButtonArea that I mentioned (right button started around 50%).

I don't think this will have a different result but I'm going to try using with real numbers instead of percentages to define the right & middle button areas. It clearly doesn't work for the AreaTopEdge/bottom of SoftButtonAreas.

EDIT: As I expected, no luck with real numbers vs percentages. This is what I expected due to the nature of this bug.

I found a solution, yes i does seems to require a kernel patch. I liked patches below.

Also, heres my 50-synaptics.conf file:

# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.

I suggest you use abs (Arch build system) to patch you kernel. Something like:

1.
sudo pacman -Sy abs

2.
sudo abs

3.
cp -r /var/abs/core/linux ~/linux

4.
cd ~/linux

5.
mkdir src

6.
Now copy the *.patch from link i provided

7.
Now adapt PKGBUILD so it will look like

8.
now type "makepkg -s"

9.
if you see something like this:
patch-3.18.6 ... FAILED (unknown public key 38DBBDC86092693E)

just do "gpg --recv-keys 38DBBDC86092693E"

10.
Try 8 again

11.
Wait until you kernel is build and packaged.

12.
Just install you kernel with "sudo pacman -U [insert your newly build package files here]"
(There is more files here)

... Bingo!

Or you can wait for it to be merget upstream and released

Thank you for sharing your configuration! I decided to wait for the official release of the kernel and I just got it. Your 50-synaptics.conf works perfectly
