Looks I'm getting same eefect with newest releases of Ubuntu and evdev drivers (tried alot of combos, throughout 2012 year). Simply, using transformation matrix with evdev driver wich inverts, scales or shift coordinates causes either jumping to border of screen or jitter when touch even happening, which makes usage of multi-display configuration with one or more touchscreens. Tested with 26.x and 3.2.x kernels, with all release since february of 2012. Using touchscreens: 3M MicroTouch EX II (since 3.x kerel their driver i sjust wrapper of evdev.. before that it calibration utility doesn't support multiple touchscreens) , also rugged BARQ screens (which supposed to be used with evdev).
This is conundrum, because even if I could even have skill to fix it and rebuild driver (but I have not enough knowledge to do so)our company would accept only official distros in production. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/832624 Title: cursor jumping to screen border Status in Unity Foundations: Won't Fix Status in “xorg-server” package in Ubuntu: Won't Fix Bug description: Even with xserver-xorg-core at version 2:1.10.1-1ubuntu1.2, incomplete valuators still cause the cursor to jump to the screen corners. http://up.tao.at/download/c8a578b047fc4fbb205c4f0bee52532e/xev_with_new_xserver ← Last tap (time 1494xxx) ended up with the cursor not where it should again (coordinates 600,675 would be correct, 1079,675 aren't). http://up.tao.at/download/69e5a847d775f8fde8185fcf9345f0d9/evtest_with_new_xserver ← incomplete valuators, both on X and Y axis.
