Public bug reported: Binary package hint: xserver-xorg-input-synaptics
The cursor motion on a trackpad is derived from the distance of the current touch location from the previous touch location. When the number of touches on the trackpad changes, the touch location may jump causing a cursor jump. This has been remedied by the following commit: http://cgit.freedesktop.org/xorg/driver/xf86-input- synaptics/commit/?id=a6ca4d2523904b7ce49edc29ba408979bdf0d45e However, the multitouch patches added to synaptics cause the change in the number of fingers to be reported one frame after the actual change. This allows a cursor jump to occur. ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Medium Assignee: Chase Douglas (chasedouglas) Status: In Progress ** Changed in: xserver-xorg-input-synaptics (Ubuntu) Status: New => In Progress ** Changed in: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided => Medium ** Changed in: xserver-xorg-input-synaptics (Ubuntu) Assignee: (unassigned) => Chase Douglas (chasedouglas) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/751525 Title: Jumpy cursor on semi-mt trackpads _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
