ALPS Touchpads Configuration

venoom27noom27 · 2010-10-31 11:26:39

I am trying to get vertical scrolling to work on my touchpad and it is a alps. I was reading on https://wiki.archlinux.org/index.php/Touchpad_Synaptics and it says to put

Section "ServerLayout"
...
InputDevice "USB Mouse" "CorePointer"
InputDevice "Touchpad" "SendCoreEvents"
EndSection

but where do you put it?
In
/etc/X11/xorg.conf.d/10-synaptics.conf
or
/etc/X11/xorg.conf.d/10-evdev.conf
or somewhere else that I have not listed.
Also my touchpad is having the same issues as listed on this tread. https://bbs.archlinux.org/viewtopic.php?id=103953 if you are interested

The wiki text says

Warning: TODO needs to be rewritten for udev

So the configuration on the wiki is for xorg.conf and not for udev, which uses the new /etc/X11/xorg.conf.d directory.

Here us my configuration and its location:

ewaller@odin:/etc/X11/xorg.conf.d 1079 %ls
05-intel.off  10-evdev.conf  10-quirks.conf  10-synaptics.conf
ewaller@odin:/etc/X11/xorg.conf.d 1080 %cat 10-synaptics.conf 
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"

        option "TapButton1" "1"
        option "TapButton2" "2"
        option "TapButton3" "3"
        option "SHMConfig" "true"
        option "CircularScrolling" "true"
        option "CircScrollTrigger" "3"
        option "LBCornerButton" "2"
        option "RBCornerButton" "3"
        option "AccelFactor" "2"
EndSection
ewaller@odin:/etc/X11/xorg.conf.d 1081 %

Works like a charm.

I justed tired your config and logged out and back in and it still does not work( meaning scrolling vertically or horizontally does not work)
When I run.
cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input7
U: Uniq=
H: Handlers=mouse0 event7
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

it shows my touch pad as being loaded as a "PS/2 Generic Mouse" so the synaptic driver is not even loaded.
That is why I was trying to figure out where to put the

Section "ServerLayout"
...
InputDevice "USB Mouse" "CorePointer"
InputDevice "Touchpad" "SendCoreEvents"
EndSection

I also installed GPointingDeviceSettings and it sees the touchpad as a PS/2 Generic Mouse

Sadly, I've no way to judge your experience. Please indulge me as I start with the basics.

You did install both xf86-input-synaptics and xf86-input-evdev ?
And then restarted Xorg?

Yes they are both installed when I installed Arch on this computer about two weeks ago.

Background this is a new computer a Dell Inspiron N5030. When I first got it about three weeks ago I installed Ubuntu 10.10 and the scrolling also did not work on the touchpad.

SO after some looking I am starting to see how configuration would take place.
1. I made a rule in /etc/udev/rules.d/ and called it 10-local.rules
2. I then inputed this into it which I had gotten from a forum

ACTION!="add|change", GOTO="xorg_synaptics_end"
KERNEL!="event*", GOTO="xorg_synaptics_end"
ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="xorg_synaptics_end"
ENV{x11_options.MaxTapTime}="300"
ENV{input.x11_options.FingerHigh}="0"
ENV{input.x11_options.MaxTapMove}="1"
ENV{input.x11_options.MaxTapTime}="300"
ENV{input.x11_options.LeftEdge}="200"
ENV{input.x11_options.RBCornerButton}="0"
ENV{input.x11_options.LTCornerButton}="3"
ENV{input.x11_options.MaxSpeed}="0.8"
ENV{input.x11_options.MinSpeed}="0.6"
ENV{input.x11_options.FastTaps}="1"
ENV{input.x11_options.AccelFactor}="0.4"
ENV{input.x11_options.HorizEdgeScroll}="1"
ENV{input.x11_options.TrackStickSpeed}="0"
ENV{input.x11_options.RightEdge}="950"
ENV{input.x11_options.TouchpadOff}="0"
LABEL="xorg_synaptics_end"

Now when I restart the computer it is still seeing the touchpad as a generic mouse under

cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0

U: Uniq=
H: Handlers=mouse0 event7
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

When I
udevadm info -a -p /devices/platform/i8042/serio1/input/input7
I get

Any ideas that would get my ALPS touchpad working?

venoom27noom27 · 2010-11-22 04:54:42

I submitted a bug for this issue https://bugzilla.kernel.org/show_bug.cgi?id=23502. After doing some research on the web I found out that the kernel is not detecting my touchpad as a alps.

john_schaf · 2011-01-29 10:03:29

Exactly the same problem here on a acer TimeLineX. Have you found a workaround for this problem ?
By the way, thanks for submitting the bug report.

venoom27noom27 · 2011-01-29 12:55:26

No I have not but a bug has also been submitted on Ubuntu's bug site launchpad https://bugs.launchpad.net/ubuntu/+sour … bug/678103. You may want to submit your own bug report since you may have different hardware then what I have.

George_K · 2011-01-29 23:03:49

I had to reduce RightEdge (and to increase TopEdge) manually on my Elantech for edge scrolling to work.

I have the same issue on Acer 1830T. Such a shame

Please take a look here: https://bbs.archlinux.org/viewtopic.php … 25#p973025
Maybe this helps.

Update

I installed Gentoo with kernel 3.1.1 and 3.1.2 on the same computer and the touchpad works with on problems.

I tried using the same kernel config from Gentoo and complied it on Arch but the touchpad did not work.

Now I also installed Fedora 16 on the same computer and the touchpad did not work either.

I am thinking that maybe a fresh install of Arch may solve this problem because I installed this Arch system in Sept. 2010. But it could be that the Gentoo patches their kernel may diff from Arch but I am not going to get into stuff I really have no idea about.?

That being said does anyone know how to use other distributions kernel sources in Arch?

Now I did start Fedora 16 off the Gentoo kernel and the Touchpad worked and did the same thing with Arch and the touchpad did not work of course this is not a workable solution since the modules are mapped to different folders so have my stuff didn't work.

Thanks for everyone's help

venoom27noom27 · 2011-12-02 01:54:23

Ok so I complied a Gentoo 3.1.4 kernel on my arch install and I had to delete a config that I made to /etc/X11/xorg.conf.d/10-synaptics.conf and now the touchpad works. I was looking at some of the patches that Gentoo kernel uses and they had pulled some from Ubuntu to fix the ALPS touchpad so if Arch could pick up these patches then this would fix this issue.

I also booted into a live cd of Ubuntu 11.10 and the touch pad does not work. I have also seen that kernel 3.2 may address these issues but I have yet to compile the release candidate yet to test.

Revised Ubuntu 11.10 touchpad does work though it is buggy at start up sometimes.
