[Desktop-packages] [Bug 1078272] Re: It's impossible to configure multiple touchscreens using evdev
It is still a problem, partially.It is possible to use coordinate transformation matrix property (TransformationMatrix option in InputClass section) to assign touchscreens to different displays, but not to different X screens. But, unless system is SLI , or , or Mosaic enabled - that is , it is supported by GPU and chipset -and that is NVIDIA specific, then even with xinerama enabled every GPU is separate X display. In that case , e.g, on x server :0 with screens :0.0, :0.1 and 0:0.2 even with proper matrix, mouse cursor simply jumps to bottom edge of screen, if coordinates do not correspond to to :0.0 - i suspect it is a bug on evdev side. realistically that makes multiple touchscreen configuration possible only with NVIDIA cards (twinview joins displays into one X screen), and in case of 3 or more displays - only with SLI or BaseMosaic -- You received this bug notification because you are a member of Desktop Packages, 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 Status in “xserver-xorg-input-evdev” package in Ubuntu: Expired Bug description: 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?

[Desktop-packages] [Bug 1078272] Re: It's impossible to configure multiple touchscreens using evdev
xop, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xserver-xorg-input-evdev REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.
