Public bug reported: We're trying to get a multi-touchscreen (multiple touchscreens not multi touch) setup working with the evdev driver in Natty Narwhal. Basically, the touchscreens are configured and working except that the mapping to the correct X screen is wrong. We set up 5 touchscreens in a row (Xorg ServerLayout "RightOf") and their corresponding touchscreen inputdevices. Using xinput we are able to create a pointer for each of the touchscreens. The following is observed then: When touching any screen, the resulting movement of the pointer is only displayed on the first X screen (there are 5 pointers visible then on this screen.). This is not at all the desired behavior. We would like to attach a touchscreen to a specific X screen.
Unfortunately, we found no way to tell the evdev driver to map a InputDevice to a X screen. Older versions of the driver (1.1.2) provided an option "AbsoluteScreen" (see http://manpages.ubuntu.com/manpages/dapper/en/man4/evdev.4.html) but the latest version hasn't anything like this. I know that the evtouch driver would provide a "ScreenNo" option, however evtouch is not available for Natty Narwhal. We also experimented with the Xorg coordinate transformation matrix, but with the result that the mouse movements where still on the first X screen. So my question is: How do I tell the evdev driver to map an InputDevice to a specific X screen? Is there an option line in xorg.conf or is there any method via xinput? ** Affects: xserver-xorg-input-evdev (Ubuntu) Importance: Undecided Status: New -- 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/1078272 Title: It's impossible to configure multiple touchscreens using evdev To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1078272/+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
