Touchpad Problems on Netbook.

[chronas999]

I am very new to this, so I apologize if this has already been covered. I have installed Sabayon onto a Dell Insprion Mini 1012 Netbook. Everything is working great with the exception of the touchpad. I can move the cursor and click just fine, but I cannot click and drag items. when I hold down the 'left click' button, I cannot use my other finger to move the cursor.

It is a synaptics touchpad. I have installed the "pointing devices" utility, but cannot find a setting in there to make this work.

Which edition of SL did you install? x86 or amd64? And which desktop environment? KDE? GNOME? Xfce? MATE?

If you don't already have a section regarding the touchpad in the file /etc/X11/xorg.conf or in a file in the directory /etc/X11/xorg.conf.d/ then create a file /etc/X11/xorg.conf.d/10-synaptics.conf containing the following:

Code: Select all

Section "InputClass"
   Identifier "touchpad"
   Driver "synaptics"
   MatchIsTouchpad "on"
      Option "TapButton1" "1"
      Option "TapButton2" "2"
      Option "TapButton3" "3"
      Option "VertEdgeScroll" "on"
      Option "VertTwoFingerScroll" "on"
      Option "HorizEdgeScroll" "on"
      Option "HorizTwoFingerScroll" "on"
      Option "CircularScrolling" "on"
      Option "CircScrollTrigger" "2"
      Option "EmulateTwoFingerMinZ" "40"
      Option "EmulateTwoFingerMinW" "8"
      Option "LeftEdge" "1700" # x coord left
      Option "RightEdge" "5300" # x coord right
      Option "TopEdge" "1700" # y coord top
      Option "BottomEdge" "4200" # y coord bottom
      Option "FingerLow" "25" # pressure below this level triggers release
      Option "FingerHigh" "30" # pressure above this level triggers touch
      Option "MaxTapTime" "180" # max time in ms for detecting tap
EndSection

and reboot. See if that makes a difference.

I am running x86 with gnome. I created the synaptics conf file, but did not experience any differences.

I do believe I have a solution!

The buttons on my touchpad are integrated into the touchpad itself, they are not independent of the touch-sensitive area. If I use a finger nail and press on the very corner of the pad, I can drag and drop. I believe that by moving the "bottom edge" spec higher up on the Y axis, it will make the bottom edge of the touchpad non-responsive to touch, thus allowing me to press the corner down and not have it register as actually touching the pad.

Ideally, though, I'd like to have multi-touch support, but I am unsure if the hardware even supports it.

I'll modify the conf file to kill the bottom portion of the touchpad and let you know how that goes.

Making progress!

Moving the bottom edge a little higher up the "Y" axis seems to work- I can place my finger in the corner and use my other to move the cursor- until I login. After logging in the entire touchpad becomes responsive again. Now it seems that there is another setting overriding the conf file once I login.
