Created attachment 116336 [details] USB device details I tried libinput-0.17.0 in combination with xf86-input-libinput 0.11.0 on my arch machine. The Xorg log prints: "[ 116.505] (EE) libinput: WALTOP Batteryless Tablet : Discarding absolute event from relative device. Please file a bug" The tablet is an Aiptek "Media Tablet Ultimate II". See the attached lsusb.txt for details.
please run evemu-record against the tablet with a pointer motion or two, thanks. easier to use for debugging

this thing claims it has REL x/y and mouse wheels - does it really? do you happen to have a link to some image of the tablet?
Yes, it has even two wheels :) Check the manual PDF. http://download.aiptek.de/Graphic%20Tablet/MediaTablet%20Ultimate%20II/
interesting. does it produce relative x/y coordinates? I wonder if switching it to "mouse" mode in windows changes the reporting of the coordinates. Regardless of that, I don't have an immediate fix here, sorry. The required fix here is to add a hwdb entry for this device to mark it as ID_INPUT_TABLET so we can deal with it appropriately. but libinput upstream doesn't have tablet support yet, so all you'd get here is a different error message, sorry. you can try the tablet-support branch from the libinput git repo though, would be great to test it on a non-wacom tablet.
Hey Peter. I tried the tablet branch and failed quickly. It crashes libinput immediately. I attached the xorg backtrack.

hmm, which commit did you test here? that bug rings a bell but I thought I had fixed it a while ago. no idea how to check this on windows either, sorry. haven't worked with windows in a long time.

I used the latest version at that moment: commit 99aa1f5dc3593826e512460a5c914a87a3a7c16a Date: Thu Jun 4 12:49:11 2015 +1000 Merge branch 'master' into tablet-support
on the tablet-support branch (not in master yet) commit 2776581d0807ab9d75ad6969f76a18158564ea16 Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Mon Jun 29 14:20:20 2015 +1000 tablet: fix check for rotation axis I'm going to close this bug as fixed, because with the right branch it'll work now. It still won't work on master, but that's a known issue and a big-ticket item anyway. no point collecting bugs for that just yet :)
