Touchpad configuration disappeared

Postby drwho on Tue Mar 26, 2013 11:05 pm

I have an Acer Aspire and Mint 14 Mate. I always have to re-enable the touchpad after each boot. Until this morning, I had to do ctrl fn f7 to enable it, but when I booted this morning, I discovered that the key combination had mysteriously changed to just fn f7. Also all my touchpad configuration options had disappeared, and the touchpad configuration tab under control center/assisstive technologies/mouse had disappeared . Apparently this is the result of an update within the last week (Mar 20 -27) (for lack of any other cause. Does anyone know how to restore the configuration options to the Control Center? When I first installed Mint I remember that I had to do something to get the touchpad configuration options to show, but I don't remember what it was. I Tried reinstalling xserver-xorg-input-synaptics to no avail. Is there some other package I should install/reinstall or...? gpointing-device-settings is installed. I noticed that there is no xorg.conf file present under /etc/x11 as what I have read seems to indicate there should be. Something else I noticed is that the touchpad is currently being recognized as "PS/2 Synaptics TouchPad" but several months ago when I was dealing with another touchpad issue, it was recognized as "synPS/2 Synaptics TouchPad". I tried running synclient -l but there is no output from this at all. I tried installing the Synaptiks pacjage, but it says "Touchpad not found". I have read bug reports that suggest that the problem might be the result of a bad kernel update? Here is a bunch of information from various terminal commands if it helps:

[solved]: Touchpad configuration disappeared

Postby drwho on Thu Mar 28, 2013 3:44 am

If there is no xorg.conf file under /etc/x11/ the touchpad tab doesnt show under assistive technologies/mouse. Since there was none, I added the xorg.conf file with the following information:

tion "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

It's still a mystery why this file disappeared but all is good now!
