Thanks Chris for that pointer! Applying the mentionned patch solves the pointer jerkiness issue when applying the "Coordinates Transformation Matrix" to my Atmel maXTouch touchscreen.
I attach the corrected patch which can be added to the current Quantal 'xserver-xorg-core' (1.13.0-0ubuntu6.1) source (in debian/patches and debian/patches/series) Cheers ** Patch added: "(for Quantal 12.10 'xserver-xorg-core' source)" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1005321/+attachment/3499782/+files/238-dix-save-touchpoint-last-coordinates-before-transform.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005321 Title: Several pointing device related problems occur when a touchscreen is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1005321/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
