Re: [LinuxR3000] Alps Touchpad in Xorg.conf [SOLVED]

Awesome!! Thanks a ton Eric! It works now.

Here's what I did.

1) I edited /etc/X11/xorg.conf and it looks like this now:

----------
Section "ServerLayout"
    Identifier  "Simple Layout"
    InputDevice "Touchpad" "SendCoreEvents"
    InputDevice "Mouse0" "CorePointer"
    InputDevice "Keyboard0" "CoreKeyboard"
    Screen      "WXGA LCD"
EndSection
.
.
.
Section "InputDevice"
   Identifier   "Touchpad"
   Driver       "synaptics"
   Option       "SendCoreEvents" "true"
   Option       "Device" "/dev/input/TouchPad"
   Option       "Protocol" "event"
   Option       "LeftEdge" "130"
   Option       "RightEdge" "840"
   Option       "TopEdge" "130"
   Option       "BottomEdge" "640"
   Option       "FingerLow" "14"
   Option       "FingerHigh" "15"
   Option       "MaxTapTime" "180"
   Option       "MaxTapMove" "110"
   Option       "ClickTime"  "0"
   Option       "MaxDoubleTapTime" "100"
   Option       "EmulateMidButtonTime" "75"
   Option       "VertScrollDelta" "20"
   Option       "HorizScrollDelta" "20"
   Option       "MinSpeed" "0.60"
   Option       "MaxSpeed" "1.10"
   Option       "AccelFactor" "0.030"
   Option       "EdgeMotionMinSpeed" "200"
   Option       "EdgeMotionMaxSpeed" "200
   Option       "UpDownScrolling" "1"
   Option       "CircularScrolling" "1"
   Option       "CircScrollDelta" "0.1"
   Option       "CircScrollTrigger" "2"
   Option       "SHMConfig" "true"
   Option       "Emulate3Buttons" "on"
EndSection
----------
The following line had to be added to the existing configuration.
Option       "ClickTime"  "0"

2) I created the file /etc/udev/rules.d/40-personal.rules and added this line to it:

BUS="serio", SYSFS{description}="i8042 Aux Port", KERNEL="event?", SYMLINK="input/TouchPad"

One more thing. I use XFCE 4.2 and am left-handed, so I had configured the mouse to work left-handed via Settings -> Mouse Settings. But the touchpad always worked the right-handed way, simply because it was never configured properly.

After I changed xorg.conf and added the udev rule that Eric sent me, the touchpad now works left-handed (I click on the right button on the touchpad instead of the left)

Thanks guys!

1. Can someone please mail me the Touchpad section in xorg.conf?
   Option "Device" "/dev/input/mouse2"
    
I don't think it is using your configuration. Synaptics requires an
event, not a mouse. A more proper dev would be /dev/input/event1. I
don't know what event it would be though. In addition, it will be
prone to change depending on start-up conditions. I use udev to give
me a /dev/input/TouchPad so it will remain static. I can help you with
that once you get the setup working and if you want the help.

  
2. How do I set eth0 or wlan0 boot up automatically on boot-up? I've
got net.eth0 and wlan0, but usually start them manually after booting.
I used to have this in my Debian 64bit, but Gentoo 64bit is different.
Does anyone have an input on this?
    
rc-update add net.wlan0 default
'default' may also be boot, but it is better to be default.  Did
someone help you on the install, because this is covered in the
install how-to (I am not trying to say anything about you not knowing
it, just that it is pecular)?
