Exactly the same happens to me in a Samsung R480 notebook, with a Synaptics touchpad. The multitouch capabilities are present, because in windows 7 (dual boot) works fine.
Notable things: 1.- The problem does solve when running one finger flat, as was mentioned. 2.- Multitouch capabilities do not work by default, I have to run an (attached) script at startup in order to make multitouch work. I also have them greyed out in mouse options. 3.- The problem appears at random, at times it starts ok and the touchpad works and sometimes it presents the bug. 4.- The problem disappears when resuming. Hope this help. My ubuntu version is Lucid. ** Attachment added: "Script that has to be run to activate multitouch capabilities" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/365943/+attachment/1580283/+files/multitouch.sh -- Mouse cursor jumps when two fingers are used https://bugs.launchpad.net/bugs/365943 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
