I had similar problem with cursor jumping randomly on my Dell E5570 with Ubuntu 16.04, but the solution posted her by Juan Hernandez did not help. I found out that my Track Stick (stored in the middle of my keyboard) is source of the problem. When I disabled it the problem just disappeared. I guess the problem is with the driver for the track stick as it worked just OK on Windows.
The following link was very helpful: https://cederlys.wordpress.com/2010/07/13/disabling-the-track-stick-in-ubuntu/#comment-694 I used the following to list the input devices: xinput list and to disable the track stick: xinput -set-prop "AlpsPS/2 ALPS DualPoint Stick" "Device Enabled" 0 Hovewer after reboot the trackpad is back on, so I added the above command to "Startup Applicationns" Regards -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1574667 Title: Mouse pointer occasionally jumps to the bottom-left corner To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1574667/+subscriptions _______________________________________________ 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
