I would like to second the above statements about the bug still being present in (L)Ubuntu 12.04 with Xorg-Server 2:1.11.4. I am using a eGalax Inc. USB TouchController like Jon Szymaniak. So I had a script calling xinput to set-props 'Evdev Axis Inversion' as well as 'Coordinate Transformation Matrix'. However, even without the axis inversion, the pointer erratically jumps around the location pressed. So it definitively seems to be an issue with applying the transformation matrix.
Using the combined "xinput set-props 'EvdevAxis Inversion' 1 0" and 'Option "Calibration" "105 1927 190 1857"' in xorg.conf.d/99.conf however gives me a decently calibrated, working touch screen without the flickering pointer. -- 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/774938 Title: Erratic cursor movement when using "Coordinate Transformation Matrix" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/774938/+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
