Hello, after commit c8b098214b44cf0585d78c460401ea7d143769f3 (Don't
store fake events in the motion history) the touchpad is unusable: the
pointer moves too fast, and it keeps on moving (in the same direction)
when the finger stops, as long as it is touching the touchpad.
It works as expected in HEAD with that commit reverted. This is the

I also found some strangeness with edge scrolling, sometimes it
generated spurious events in the opposite direction (i.e. scroll down
but get several button 4 events, instead of one button 5). I'm unable to
reproduce it now with the commit reverted, but I'm not sure it's the
same bug.

This bug did not exist on Ubuntu 11.10 with default X stack.
The pointer sometimes keeps moving in the same direction when the finger stops,
and the pointer moves too fast.
Small and precise movements are unpredictable, so the touchpad is nearly
unusable for text edit, or even clicking on window controls.
I had to set speed and acceleration to the lowest value to use this touchpad,
but this is not even a real workaround.
I know this bug is known on the debian and archlinux bugtrackers, users
report the same issue on launchpad.
I get the following outputs :

Ugh, at least with the Alps touchpad on my Thinkpad X301 the new cursor behaviour makes clicking links feel like playing bomberman in an ice- level. The cursor is constantly overshooting.

This is Trackstick Emulation mode, and it’s super-annoying. I’ve read «man synaptics» up-and-down and there is no clear way to disable this. Is it FingerPress? To what level do I have to set it to disable? 256? There are other settings that have been introduced and set zto default. And also there are settings that have been disabled. Before the upgrade you could coast after scrolling, giving you kinetic-like scrolling behaviour. This is not active anymore. And, when I scroll down, the scrolled pane sometimes jumps /up/ a certain distance. Right now it feels really awkward to use the touchpad (Alps here). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/921082 Title: after touchpad movement and stop, pointer continues in same direction at a steady pace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/921082/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
