Created attachment 132013 [details] [review] 0001-doc-Fix-mistake-in-Matrix-example-to-relect-only-X-a.patch https://github.com/TizenTeam/libinput/commit/048cad467afe535d15de50ddc7ad23ded8888716.patch oops, yep, definitely a mistake here, thanks. But master on that branch is 762a2 atm, as opposed to 048cad. Which one is the one to use? Pushed the 762a2 from the github repo as 4cf9f8bee19104d60031dd040f5758a10ed805b5, thanks Thanks, for the record: https://cgit.freedesktop.org/wayland/libinput/commit/?id=4cf9f8bee19104d60031dd040f5758a10ed805b5 On device is known as CARTFT's CVL1010:, used this rule: LIBINPUT_CALIBRATION_MATRIX="-1 0 1 0 1 0" usbv="0eef" usbd="0001" file="/etc/udev/rules.d/99-${usbv}-${usbd}.rules" cat<<EOF>"$file" ACTION=="add|change", KERNEL=="event[0-9]*", \ ENV{ID_VENDOR_ID}=="${usbv}", ENV{ID_MODEL_ID}=="${usbd}", \ ENV{ID_INPUT_TOUCHSCREEN}="1", ENV{ID_INPUT_TABLET}="0", ENV{ID_INPUT_MOUSE}="0",\ ENV{LIBINPUT_CALIBRATION_MATRIX}="${LIBINPUT_CALIBRATION_MATRIX}" EOF http://www.cartft.com/en/catalog/il/1589 https://www.slideshare.net/SamsungOSG/toward-ocf-automotive-profile/8#iotivity-agl-demo-platform |

Subject: [PATCH] doc: Fix mistake in Matrix example to relect only X along Y axis On some devices, X coordidate is not working well, as if it was swapped, (click on right, appear on left and vice versa). To sort this issue, coordidates should be reflected on Y axis: - new X prosition is changed (width is substracted by X position) - Y is unchanged (the mistake was here, it was set to X) In landscape (or portrait) mode: [ x ] [ y ] [ 1 ] * [ -1 0 1 ] [ x' ] = -x + 0*y + 1*width [ 0 1 0 ] [ y' ] = 0*x + 1*y + 0*height [ 0 0 1 ] [ 1 ] This was verified using this touch screen.
