 Posted: Wed Sep 10, 2014 10:15 pm Post subject: [Solved]Changing ALPS/Synaptics touchpad Sensitivity |
 |
|
So I have this ALPS touchpad and I don't know how to change the sensitivity of it.
It's been bothering me a little because I am not used to dragging from on edge
of the touchpad to the other and only moving 3/4 of the screen.
I have a config file in my /etc/X11/xorg.conf.d/50-synaptics.conf but I dont know what to add to change the sensitivity.
It would be nice to know how to double-tap and hold to drag and make the 1 tap registry faster.
right now when I tap once, it takes about 20 milisecs for it to register as a left-mouse click.

| There's two utilities that I know of that you can use kde-misc/kcm_touchpad and kde-misc/synaptiks. The latter one works best for me. I was never able to get it right with 50-synaptics.conf. |

That's what I have in the cofig file for synaptics touchpad and it works well: | Code: | # /etc/X11/xorg.conf.d/synaptics.conf
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "VertEdgeScroll" "on"
Option "TapButton1" "1"
EndSection |

Could not find any information about the relevance of numbering or naming in general. Even this naming works and there are no complaints in /var/log/Xorg.0.log | Quote: | | /etc/X11/xorg.conf.d/device_no_vesa.conf |

Got some useful stuff from that (SingleTapTimeout),
but still cant seem to configure the sensitivity.
https://wiki.archlinux.org/index.php/Touchpad_Synaptics
It shows how to use xinput to get the capabilities of ur touchpad.
Here's mine: | Code: | $ xinput list-props "AlpsPS/2 ALPS GlidePoint" | grep Capabilities
Synaptics Capabilities (308): 1, 1, 1, 0, 0, 1, 0 |
From the example:
1 means yes; 0 means no
(1) device has a physical left button
(0) device does not have a physical middle button
(1) device has a physical right button
(0) device does not support two-finger detection
(0) device does not support three-finger detection
(1) device can configure vertical resolution
(1) device can configure horizontal resolution
What stumped me was that according to this guide, it says that I can configure my vertical resolution (I'm guessing this is the sensitivity) but I can't configure my horizontal resolution :/ |

I use xinput to reduce the touchpad sensitivity when I extend the desktop on my second monitor. https://bbs.archlinux.org/viewtopic.php?pid=963650#p963650
changing the Constant Deceleration works best for me.
