I encountered this bug with Ubuntu 12.10 beta 1 installed on A Lenovo T61p laptop. It only seemed to be an issue when using my Genius i608XE graphics tablet. The bug was so severe I had to uninstall and revert to 12.04. When Beta 2 came out I tried installing in Virtualbox to see if the bug was still present, which it is. I think it only affects absolute pointing devices so disabling mouse integration in Virtualbox would probably make the issue go away for many users.
The symptoms were that as I moved the stylus around it would frequently jump all the way to the left, or to the top, and often to the top left of the screen. Naturally this made drawing and writing impossible. On the bright side the pressure sensitivity for the tablet was working in 12.10! (can't get it to work in 12.04) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1041063 Title: mouse pointer periodically leaps to left and top of screen with absolute pointing devices To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1041063/+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
