I used to be able to double-tap and hold on my touchpad to drag and drop things. Since I upgraded to oneric ocelot it only works 10% of the time. What program are they using to log the touchpad and how can I change it back. Both people who upgraded and who installed it directly reported the same problem so it appears to be the fault of oneric.
I have a half answer for you and am having the same problem. The 10% of the time it works you are probably tapping twice very fast, that's when it actually works as you want. You can change your behavior (tap faster twice then drag) to get what you want, but a fuller solution fixing the double tap timing along with drag would be ideal.
I have no real solution but can tell you something that doesn't work but should. Go to launcher / search using the super key (windows key usually), type mouse, then choose "Mouse and Touchpad". You can change the double click time spacing and double click will trigger with longer time between taps but the double click then drag motion won't be affected. I personally notice this when trying to select text. I'd upvote this post but don't have enough repuation... Accept this as a partial answer and I'll upvote when I get enough rep. Hope this helps, found any better solution?
This solution woks for me
From the post:
One of the issues introduced by Ubuntu 11.10 on my Eee PC 901 is touchpad dragging. The tap-and-drag gesture, for moving the cursor with the mouse button depressed, is too sensitive. I have to tap as fast I can to activate the gesture every time
Run this command to get the timeout before a tap is interpreted as a single tap: synclient | grep "SingleTapTimeout"
On my system this option was set to 180, which is too fast. Run this command to double the timeout to 360: synclient SingleTapTimeout=360
Thanks go to Tom.
I found a persistent fix, even after suspending, following these steps.
First, create a file with your configuration script:
Second, make it executable:
And finally, run the following command replacing "<user>" with your user name:
Then reboot, or logout & login, or suspend & resume, or restart GNOME.
For more information about this fix, see this blog post.
For me the issue was generated by
to do a temp test run this command
then if it is ok you can edit your xorg configuration file
