I would like to confirm the bug, and provide additional data. My definition of "slow": when I move my finger at 1 mm/s the cursor does not move *at all*. Same when I roll the tip of my finger to drive the cursor where I need it to be (that's what I usually do when I need single-pixel precision).
I can watch the events generated by the kernel with synclient, but all of them are ignored by X up to a certain motion speed, beyond which the cursor starts moving, but in jerky sort of way. For me, this started happening very recently (about 2 days ago), but I was mostly reading during that time and didn't notice a definite event that I could link to the change. If this is indeed caused by xserver-xorg-input-synaptics, I would like to know which was the last working version. I did a lot of precise work in Gimp just last weekend, and did not notice any inconvenience. In between, I have upgraded my nvidia-glx-180 to 185, and that is the only upgrade I am aware of, although I can't see how it would be related to the touchpad problem. Now I am unable to use the touchpad for anything except selecting windows: I can't cut and paste and I can't even reliably put the cursor on the right line in a text editor. At the same time, external mice, pen tablet and the built-in track stick work smoothly. xserver-xorg-input-synaptics: Installed: 0.99.3-2ubuntu5 Candidate: 0.99.3-2ubuntu5 Version table: *** 0.99.3-2ubuntu5 0 500 http://ppa.launchpad.net jaunty/main Packages 100 /var/lib/dpkg/status 0.99.3-2ubuntu4 0 500 http://archive.ubuntu.com jaunty/main Packages "AlpsPS/2 ALPS GlidePoint" id=2 [XExtensionPointer] Num_buttons is 12 Num_axes is 2 Mode is Relative Motion_buffer is 256 Axis 0 : Min_value is 0 Max_value is 1023 Resolution is 1 Axis 1 : Min_value is 0 Max_value is 767 Resolution is 1 It's on Dell m4300 running Jaunty. --Gene -- touchpad mouse stutters/stops on slow movement https://bugs.launchpad.net/bugs/379517 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
