I'm not convinced that this is a duplicate of " Bug #868400: Synaptics touchpad stops working - two syndaemon instances running." since I do not have two instances running that I can find (ps -ef doesn't show 2). Things I have noticed, though: - I don't know that it's 100%, but it's much more frequent when "Disable mouse when typing" is set. This is my usual setting on boot since I use a USB mouse most of the time specifically because of this problem. - It acts as if the touchpad is "locked" into some gesture state. In particular, when the mouse won't move, instead a one finger gesture on the touchpad results in TWO-finger vertical scrolling. I.e., as if it thought it was still in two finger mode when I'm only using one finger. (Was state saved/not cleared when the touchpad was enabled/disabled?) I've had other cases where some motion seemed to "reset" it to a known good and working state, but not reliably. But it looks like a state- holdover somewhere to me. - The touchpad isn't "off" -- it is clearly responding and scrolling -- although it should be interpreting a single finger gesture to move the mouse, not to scroll as it is doing. - I'm not positive about this, but I think I even had "enable mouse clicks by touchpad" set one time, and when in the bad state, it would not respond to mouseclicks either. This is Ubuntu Desktop 32-bit, 12.04 and up to date as of 02/18/2013, on Asus 1215N netbook. The only odd thing about the install is this is the Nvidia Optimus graphics, so I have both Jupiter and Bumblebee installed, but only to disable the fast graphics Nvidia card (using Intel only) to save on battery and heat. Settings are: - Disable touchpad while typing - Enable 2 finger (vertical) scrolling - Speeds set all the way to left (slow) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/872885 Title: Synaptics touchpad randomly stops working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/872885/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
