Bug Description

I have an Eee PC 701 4G and I installed Karmic Beta today. My touch pad doesn't seem to work correctly. I can move the cursor, but it doesn't detect tapping with my finger, I have to use the button.

I see this error in dmesg:
[ 17.277222] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input9

This may be a deliberate UI change. I had the same problem. I found in UNR karmic daily 20091006 that the System Preferences "Mouse" setting now has a "Touchpad" tab, containing a checkbox to "Enable mouse clicks with touchpad" (and some other settings).

When I enabled it here, tapping on the touchpad started working.

This appears to be a regression, since in previous releases, tapping just worked without dinking with settings.

See ChangeLog here: . It isn't specific about stating that they wanted to change this behavior.

John Gilmore (gnu-gilmore) wrote :

There are now more than a dozen bugs reported against this. See the original bug report at #378391.

The problem appears to be that as people report the bug, they are marked as dups and lniked to that bug -- but that one is marked "Fix Released". So nobody does anything to fix the bug, which is that the behavior regressed against Jaunty. (The fact that you can go into a Preferences item and restore the Jaunty behavior is nice, but the bug is that the Jaunty behavior changed. What worked in Jaunty does not work in Karmic.)

All that's needed to *really* fix this bug is to change the default preference -- so that tapping touchpads works by default, rather than only after you enable them.

John Gilmore (gnu-gilmore) wrote :

This is not a ($*#$*#( duplicate! The problem is the regression from Jaunty. That problem was not fixed by adding a new Control Panel item that re-enables the old behavior. The problem is that you NEED to re-enable the old behavior.

   The behavior in realease Karmic has changed. You will be able to try it on a live cd and install tommorow. "Enable mouse clicks with touchpad" is now enabled by default. It has had this behavior since RC build.

Hi Paulo,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 441013

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

This bug appears to have been fixed. The problem is as reported in comments #3 to #4, and the fix was reported in #5. Someone fixed the default value in the release. I just tested this on Lucid and it worked for me. (I don't have an EEE PC but my Acer Aspire One D250 touchpad had the same trouble before the fix went in.)

Why this would need kernel logs or upstream testing, I have no idea. I think the problem is either some automated robot, or else a human acting like one, added those tags to this bug report.

John Gilmore (gnu-gilmore) wrote :

Oh, I see. If you add tags like "needs-upstream-testing" to a bug, then it becomes "incomplete", so then a robot will expire it a few months later. It's a cheat to get bugs to go away. The product is so much better when bug reports get swept under the rug by people or robots who don't actually understand them.

    Not at all. i use the script to help me manage the 10,000+ bug reports that I am responsible for. I ask for the further testing in cases where it is needed and triage the bugs based on the responsiveness of the reporters. If I get the data I need, then I can put a legitimate bug in front of a Kernel Engineer rather than a bug that seems serious that no one is responding on.

    Are you able to confirm that this has been fixed as stated by John above?
