This can be adjusted by modifying the coordinates transformation matrix for the touchscreen using xinput. However, other problems arise after doing that. See this bug for more details: https://bugs.freedesktop.org/show_bug.cgi?id=50664

However, they've been reported against xorg, without specifying the evdev package. ** Bug watch added: freedesktop.org Bugzilla #50664 https://bugs.freedesktop.org/show_bug.cgi?id=50664 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/666604 Title: Touchscreen unusual in multi-head system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/666604/+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
