Try each mouse device until you see your panel. $ udevadm info -a -p /sys/class/input/mouse0 I did this by testing all the mouse* devices in /sys/class/input with the following command: Determine which udev device corresponds to your panel. If not, you can undo the calibration with this reset command: The touchscreen should be calibrated now. $ xinput set-prop 'Fujitsu Component USB Touch Panel' 'libinput Calibration Matrix' a, 0.0, c, 0.0, e, f, 0.0, 0.0, 1.0 Test the values with the following command (replace a, c, e, and f with your calculated numbers): We now need to calculate four values, called 'a', 'c', 'e', and 'f' ( reference).Р”Р„ = (screen_width * 6 / 8) / (click_3_X - click_0_X)Р”В¬ = ((screen_width / 8) - (a * click_0_X)) / screen_widthР”В® = (screen_height * 6 / 8) / (click_3_Y - click_0_Y)Р”Р‡ = ((screen_height / 8) - (e * click_0_Y)) / screen_heightР”В§. We need the X and Y values from click 0 and click 3. Run xinput_calibrator in verbose mode:Р”Вo the calibration, then look for the DEBUG output lines: $ xinput list-props 'Fujitsu Component USB Touch Panel' | grep 'libinput Calibration Matrix' Verify your current calibration with this command (replace panel name): Mine was 'Fujitsu Component USB Touch Panel'.Р”Р€. Find your touchpanel name with the command: Delete all xorg conf files for calibration and reload X.Р”Сћ.

Here's my notes on how to do it manually:Р”РЋ. This could easily be scripted / xinput_calibrator forked, but I'm too lazy to do that at the moment. I worked out a very messy way of recalibrating. On my Panasonic CF-30, the xorg conf file generated by xinput_calibrator does not work with libinput.

But the hard way is still relevant when xrandr cannot identify the separate screens because they've been merged into one large screen. As the header says, the two pages need merging. This page is now showing only the hard way. Xinput -map-to-output $(xinput list -id-only 'Advanced Silicon S.A CoolTouch(TM) System') DVI-0 The spreadsheet method is obsolete in most casesР”Р„s described on the Touchscreen page, now I can do this instead:

Here is the google doc of the calculator: It really should not be this difficult to do this, but your instructions worked *perfectly* for me. This document is amazing, I created a google docs calculator to build the command for me. Vandyswa ( talk) 01:19, 6 October 2013 (UTC) Andy Valencia The most useful article on X's transformation matrices that I could find! Of the screen area, these coefficients need to be negative. Also, for cases where the touchscreen area is a subset It's easier to see the point of c1 and c3's equations if you have that fact in mind. If you're in there, you might mention that all values are normalized WRT 1.0 before being multiplied by this On my device, the ratio total_width/touch_area_width is the right value to use for c0. Smaller than the total width, the scaling factor will be less than 1, and thus make the result even smaller yet. 8 Mention installing the qt5-virtualkeyboard package?Р”Р„re you sure about your math? Given the ratio touch_area_width / total_width, you're saying that if the touch area is.6 Comments on making transformation matrix permanent.5 Comments on matrix, fractional coordinates.3 the spreadsheet method is obsolete in most cases.
