tap-to-click and edge-scrolling broken in Jaunty

[Max Bowsher]

Binary package hint: xfree86-driver-synaptics

As of today's package update from xserver-xorg-input-synaptics 0.15.2-0ubuntu8 to 0.99.3-1ubuntu1, tap-to-click and edge-scrolling no longer work on my Acer Aspire One.

Rolling back the update restores correct functionality.

Enabling the synaptics driver's SHMConfig option, and dumping its configuration values with "synclient -l" reveals a number of differences between the intrepid and jaunty versions of the driver:

Resetting them with synclient allows the broken features to work.... briefly. It seems something is causing them to reset within a minute or so. I'm not sure if that's all part of the same bug, or a whole different problem.

[Tormod Volden (tormodvolden)]

On my Aver Travelmate 8100, the tap-to-click was lost, but edge scrolling works.

[Luca Zorzi (lucazorzi91)]

Also on my Acer Aspire 5633 WLMi tap-to-click doesn't work, but scrolling (both horizotal and vertical) does work.

[Max Bowsher (maxb)]

Likely same issue as bug 320585, though one notes a loss of edge-scrolling and the other does not. The difference could be model-specific.

[Max Bowsher (maxb)]

See also bug 320804, I've marked it is a duplicate of this one, it contains some more diagnostic attachments.

[Alberto Milone (albertomilone)]

The attached patch enabled tap-to-click even when a physical left button is available.

[Alberto Milone (albertomilone)]

Enable vertical scrolling even when doubletap is available.

[Alberto Milone (albertomilone)]

This is a big debdiff with an updated changelog and all my patches from this bug report, from bug 320639 and from bug 320585.

[John S. Gruber (jsjgruber)]

While waiting for the above patches the following command works for me to enable tap-to-click:

xinput set-int-prop 7 258 8 2 3 0 0 1 0 0

[John S. Gruber (jsjgruber)]

Sorry, I should have mentioned:

 7 is the device number reported for the touchpad by "xinput -list" and 258 is the property called
Synaptics Tap Action by "xinput list-props 7"

Others will no doubt see different device numbers and a different set of property numbers.

[Jonas Pedersen (jonasped)]

Is these patches the right way to go? The main problem I have is that edge scroll no longer works (it is the only feature that I miss) and I looked at the patch. The current way is to do some auto detection of edge scroll capability. After the patch it is always enabled. Isn't more correct to correct the auto detection instead of always turning it on? I don't have any knowledge of the xserver-xorg-input-synaptics package, so I might be wrong.

[Alberto Milone (albertomilone)]

Jonas: currently the vertical edge scroll is enabled only if doubletap is not detected. With my patch the edge scroll is enabled in either case.

[Romain1101 (romainmadala)]

John,

---------------

While waiting for the above patches the following command works for me to enable tap-to-click:

xinput set-int-prop 7 258 8 2 3 0 0 1 0 0

---------------

by typing the correct parameters it worked for me as well !! great !
Now tap-clicking is enabled !!!

But edge scrolling doesn't work !!
I've tried to put the 1 value to "edge motion always" without result !!

[ilowman (ianl-eidosnet)]

xinput set-int-prop 7 258 8 2 3 0 0 1 0 0 worked for me too.

I've realised that although I no longer have edge scrolling I do have 2 finger scrolling working which I've never had before.

I guess to get the edge scrolling back I need to disable the 2 finger scrolling first.

[John S. Gruber (jsjgruber)]

@Romain1101,

Doing xinput list-props 7 (substituting for your device number) do you have the first number
of "Synaptics Edge Scrolling" as a 1? This is what I believe is being set to True by Alberto's patch. I'll bet that's what you need. Perhaps the double click detection is something you have and I don't because this is already a 1 for me.

My edge motion always is 0 and my vertical scrolling works. I do not have a special area of the touchpad for scrolling as I read about in some of the documentation, it is simply the right side of the normal touchpad I use.

If the x value for the edge is higherfor you than before and you have a smaller touchpad than I do perhaps that could explain our different results. You might try lowering the second value of "Synaptics Edges", though my value for this is 1532, rather than the 6051 reported above by Max.

I try to figure out what the various xinput properties are by comparing the xinput properties list to the output of "man synaptics", the xorg.conf parameters.

Just some ideas. I hope one helps.

@Alberto:

Thanks for the fast patches. Wow!

Do you think that palm detection ought to be turned on by default as before or should Ubuntu follow upstream?

In my case doubletap don't work. Checked the code in the old version and
can see that the scroll is always enabled as well, so assume no issue
doing it in the new version as well.

[Jonas Pedersen (jonasped)]

Just updated to a new version (0.99.3-1ubuntu2) and that solved my issues. I updated from main mirror, so it might not be available at the mirrors yet. Please try to update to new version when it hit the mirrors.

Thanks for fast resolution :-)

[Romain1101 (romainmadala)]

@John ,

Well as i said before :

Putting the right value - in my case - xinput set-int-prop 4 Synaptics Tap Action(303) 8 2 3 0 0 1 0 0
enables the tap-to-click.

Then I succeeded by typing "xinput set-int-prop 4 Synaptics Edge Scrolling (291) 8 1 1 1
to enable my edge scrolling.

But these changes come back to their initial value as soon as I reboot my pc.
What can I do to fix this ?

Then I went and saw that line in synaptics.c
who put the value at TRUE if double-tap isn't detected...
so i changed it to "TRUE" directly as does the patch that has been provided here...

my question is...then what ?? What I have to do to compile this so as to install it with apt-get ?

If it may help, i provide my xinput output.

[Romain1101 (romainmadala)]

Actually I don't know what is the "2 fingers scrolling" ?
Could u tell me what it consist to perform on my touchpad ?

I think the easiest thing for you is to wait some hours and wait for
version 0.99.3-1ubuntu2 shows up on the mirrors. Looks like the patch is
included in that version. Scroll is working for me again.

/Jonas

[Max Bowsher (maxb)]

OK, so -1ubuntu2 has fixed tap-to-click for me, but....

When I first logged in, edge-scrolling was working. About 2 minutes later, it had ceased to work!??

/me rolls back to the Intrepid package again for now...

[John S. Gruber (jsjgruber)]

@Romain1101:
I expect that we will see the launchpad janitor add some messages here about a fix being released (I don't know for sure) and if so it will automatically change the status. Some time after that (minutes or hours, not days) you should see the updates are available icon in your panel and then you can just allow those updates as you usually do. If you look at the packages first you should see xserver-xorg-input-synaptics 0.99.3-1uuntu2 and those will be Alberto's patches.

You won't have to use apt-get, but once you see them in the update manager you can close the update manager and use apt-get if you want. If not it will all be automatic.

My guess is that those who have tested the new package already have downloaded it from packages.ubuntu.com and installed the downloaded .deb with a lower level program. I'm going to wait myself.

[Romain1101 (romainmadala)]

@John:

Well I was able yesterday evening to upate the package.
Everything works fine!

Nothing to say except that the pointer is now such stable that I'm regreting the motion of my pointer
yesterday which was casi unstable and was able to move very quickly !
Such a way that keeping only my finger on the pad without motion and the pointer beginned to shake !!

No pasa nada !!

Where I can read that the new package features the patch from yesterday ???
I mean yesterday we were really talking with someone who put the new-good pkg online ?

Bye

Someone to teach me this ???

Is it too slow? Too sensitive? Please explain the problem more in detail.

[Romain1101 (romainmadala)]

@Alberto...

About my pointer,
"sensitive" That's the word I missed in my previous mail -> My pointer isn't sensitive enough for me !!
I don't know exactly to describe, just that yesterday it was a bit crazier !!! and I liked that...
today it's like I have to push harder, with a low accelFactor - that I've set upper !
So I'm reading the patches added to the package and I read the ultimate

"* 107_reduce_cursor_speed.patch:
 - Reduce the cursor speed. (LP: #320639)"

I'm gonna read what it changed, maybe that the point !!!

@Alberto,

Ok I set back the value of MaxSpeed and MinSpeed as they were yesterday...It went back to that behaviour I was talking about !!
nice !! I changed it with synclient, I will see if it comes back rebooting the PC.

Anyway, nice to have some people like you, I learned a lot !!
I didn't know that I could middle/right-click with multiple fingers with my touchpad !!!

I just miss the ultimate info -> how to roll back to a previous version when a new package doesn't come good !!

Thanks 4 everything!

you can do something like this:

Also, can you attach the output of this command again (after settings the values which work for you)?

0.99.3-1ubuntu2 fixes tap-to-click and edge scrolling on my Acer, but left button click doesn't work reliably anymore. Very often I have to click twice, and I suspect that it's because behind the scenes it clicks too often. Single left click also can produce left+right and paste current clipboard contents accidentally.

[Trip Ericson (rovfan)]

Confirming Sergey's issues. I've got them as well.

[Nicolò Chieffo (yelo3)]

That patch does not fix my alps TP. I have to add RightEdge=800
And another thing I noticed is that the tap has a lag of 0.5~1 second. Is this tapping problem also valid to you?
Thanks

0.99.3-2ubuntu1 improves the situation: clicking left button almost never produces a left+right click for me, edge scrolling and double finger scrolling (which I've never used before) work, as does tap-to-click. Left click is still jittery (sometimes it still does left+right; left click and drag always produces left+right instead), but it's much better. I'm attaching the output of xinput. Thank you!

[Damon Lynch (dlynch3)]

Hardware: ALPS GlidePoint.

Alberto Milone's PPA package solved the bug where edge scrolling did not work. It now works just fine. Thanks.

[Max Bowsher (maxb)]

Reopening again, edge scrolling still broken on Aspire One, as described in https://bugs.launchpad.net/ubuntu/+source/xfree86-driver-synaptics/+bug/320632/comments/42.

It's not a pressure issue as some have suggested since - in that comment I specifically note that RightEdge is misbehaving in mysterious ways.

[Alberto Milone (albertomilone)]

Max Bowsher: can you try commenting out the whole "InputDevice" section about your touchpad from your xorg.conf (and its entry in the "ServerLayout" section, if you have one) and restarting X, please?

[Max Bowsher (maxb)]

My xorg.conf has no "InputDevice" sections - only the ultra-minimal "Device", "Monitor" and "Screen" sections that are the jaunty default, and a "ServerFlags" setting "DontZap" "false".

[Alistair Buxton (a-j-buxton)]

Max,

You didn't mention if you actually tried the FingerLow/FingerHigh thing. I had exactly the same problem, same symptoms, on exactly the same hardware. I didn't think the fix would work but I tried it anyway, and it did work.

[Max Bowsher (maxb)]

Alistair:

I didn't, there really didn't seem to be any point when I had already determined that the problem was the RightEdge setting spuriously resetting itself to a too-large value.

For the sake of completeness, I tried the Finger{Low,High} setting: it didn't fix the bug. It did allow some edgescrolling, but it was necessary to awkwardly stroke only the extreme edge of the touchpad. Meanwhile, the changed settings made the touchpad awkwardly oversensitive for ordinary pointer movement.

The Finger{Low,High} settings should be left at their current defaults - what needs to be done is to find and fix whatever keeps spuriously resetting the RightEdge value.

I've just done some testing, and I've narrowed down the exact behaviour I observe:

I set a loop of "while sleep 1; do synclient -l | fgrep RightEdge; done" running to monitor the RightEdge value.

Immediately after bootup, the value is 5132. Scrolling *works*! If I very diligently avoid touching the extreme right edge of the touchpad, scrolling continues to work. The moment I touch the extreme right edge of the touchpad, the value printed from the monitor loop changes to 6142. Scrolling now doesn't work, no matter how carefully I touch only the extreme right edge when trying to scroll. I run "synclient RightEdge=5132" - scrolling works again! I touch the right edge - RightEdge reverts to 6142, scrolling no longer works.

Weird.

I hope this means something to someone more familiar with the driver source.

[Adam Sommer (asommer)]

I just wanted to comment that I am still experiencing the same bug as Max Bowsher, with the same results using the synclient RightEdge=5132 command.

I am experiencing this on a Dell Mini 9. I did further testing booting from an Intrepid USB drive and didn't have the loss of Scrolling issue.

If there is any additional information I can provide, or anything I can test, please let me know.

Thanks,
Adam

[Max Bowsher (maxb)]

I have now git bisected. In retrospect that was unnecessary, if only I'd read the commit messages more carefully. The culprit is:

commit 3db3f4e04c7038477a03b092c55dfd063224f034

    Auto-adjust right_edge for touchpads with hardware scroll area.

    If RightEdge is specified as a config option, ignore the SpecialScrollArea.
    Otherwise, adjust right_edge to the bounds of the hardware scroll area.

which is "auto-adjusting" my right edge off the edge of my touchpad

[Alistair Buxton (a-j-buxton)]

I found that the fingerlow/high fix moved the scroll area right as well, but for me it was an improvement. Previously the scroll area was so far from the right edge of the pad, that it didn't actually reach all the way to the edge.

[Max Bowsher (maxb)]

Judging by some careful experimentation with synclient -m, it's not that it moves the region, it's that if you're only touching the very edge of the pad, it's impossible to get more that about 25 pressure units.

[Nicolò Chieffo (yelo3)]

A question to Alberto: I missed why you still haven't pushed the
update into jaunty

[Bryce Harrington (bryce)]

Thanks for narrowing it down to that change. I think just reverting that patch is probably the wrong thing to do, since that would regress the feature entirely. Instead, further analysis is needed in order to discern why with this patch it is failing in this fashion. My guess is that it is incorrectly making automatic adjustment assumptions with this hardware.

Also, I'm beginning to suspect this may have a hardware-specific aspect to it, in which case I'm unsure that blocking the release on this is warranted. But I'll leave the milestone/target alone for now; I think a fix is within sight.

Alberto, do you have further comments/plans on this that need accounted for?

[Alberto Milone (albertomilone)]

I haven't had the time to look at this very hardware specific bug but I think I can try to revert patch only for ALPS touchpads so as not to cause regressions with synaptics touchpads.

[Nicolò Chieffo (yelo3)]

Is it possible to ship a hal .fdi file in the package so that ALPS
touchpads will work?

[Alberto Milone (albertomilone)]

The attached debdiff should solve the problem. The change is minimal and is just an addition to my previous patch so that if an ALPS touchpad is detected the right edge is not auto adjusted.

[Max Bowsher (maxb)]

Alberto:

maxb@aao:~$ lshal | fgrep -i alps
maxb@aao:~$ lshal | fgrep -i synap
  info.product = 'SynPS/2 Synaptics TouchPad' (string)
  input.product = 'SynPS/2 Synaptics TouchPad' (string)
  input.x11_driver = 'synaptics' (string)
maxb@aao:~$

It appears the Aspire One's touchpad is not an ALPS device?

[Alberto Milone (albertomilone)]

Ok, I'll work on another patch but we'll have to test the package for regressions as it will affect all synaptics touchpads.

[Alberto Milone (albertomilone)]

The attached debdiff sets the SpecialScrollArea to False by default.

[Alberto Milone (albertomilone)]

I have uploaded the package to my PPA, can you try it and let me know how it goes, please?

Hi Alberto,

This package fixed the edge-scrolling disappearing after a few minutes. Thanks !

Hi!

My Synaptic touchpad worked fine and still does with the package from the PPA.

HTH.

[Serbitar (serbitar-sessionmob)]

Tapping and scrolling stopped working on my SynPS/2 Synaptics TouchPad after version xserver-xorg-input-synaptics_0.99.3-2ubuntu3_amd64.deb. So 0.99.3-2ubuntu4 is the first version it ceased to work.
The bug is still present in 1.1.0-0ubuntu1.

[Alberto Milone (albertomilone)]

Serbitar: can you attach the output of this command, please?
xinput list-props name_of_your_synaptic_device

replace "name_of_your_synaptic_device" with the name of your synaptic device (as reported by "xinput list")

[Serbitar (serbitar-sessionmob)]

Ive attached the output with the working package 0.99.3-2ubuntu3 and the non-working one 1.1.0-0ubuntu1

[Alberto Milone (albertomilone)]

Serbitar: 1.1.0-0ubuntu1 is not available in Ubuntu Jaunty. Can you please install version 0.99.3-2ubuntu4, restart the xserver and attach the output of the same command?

[Michael Marley (mamarley)]

Serbitar appears to be using the package from my PPA. Sorry about that.

[Serbitar (serbitar-sessionmob)]

True. 0.99.3-2ubuntu4 wroks. I thought I had it installed when the bug occured the first time. My fault. Thanks for the time.

[Alberto Milone (albertomilone)]

Serbitar, Michael: thanks for making it clear that the problem affects the package in the PPA and not the package in Ubuntu.

I think this bug is finally fixed.

[mobile (carlleach)]

The package doesn't appear to be available in the location listed below. How do I obtain it?

I installed Ubuntu 9.04 NBR Beta last night and I have the edge scrolling issue described above on my Asus Eee PC 701, i.e. it initially works ok then stops working after a few minutes. Wouldn't the latest version of this package be installed during installation of the OS? I will check which version I have tonight.

Is anything special needed to (rei-)enable two-finger scrolling, etc? I used to have two-finger scrolling on Jaunty, but it is gone now. I have edge scrolling and tap-to-click. And, as others noted, if I install Mike Marley's newer driver, I lose even that.

To be sure of which version I am running, after forcing a delete of Mike's driver, reinstalling and rebooting:
