Re: Can't Rotate Full-size Touchscreen (can rotate display though)

I have an elo 12" touch panel that I can finally get the touch rotated 90 deg cw but can't get it calibrated. The arrows fall short of the x's when using the calibration program. Tried clicking x's with a mouse and using those numbers and touching past the x's to try hitting the spot with the arrow...

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

In case anyone is looking for it at the same time, I'm using this to make an interactive kiosk and I'm using this to be able to autoload a webpage in full screen mode. There are a bunch of ways to do this, but I found this file in the pi autostart subdir of .config to be pretty simple to do. Here's ...

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

Last piece of the puzzle, similar to what Dougie had mentioned, create a conf file in /usr/share/X11/xorg.conf.d/ I called mine 90-right-rotate.conf and use the following: Section "InputClass" Identifier "RotateTouchCW" MatchProduct "eGalax Inc. USB TouchController" Option "TransformationMatrix" "0 ...

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

I was able to find a nice article on xinput Coordinate Transformation Matrix here: https://wiki.ubuntu.com/X/InputCoordinateTransformation So I was using the Left rotation transformation matrix and I needed the right rotation transform which was: xinput set-prop "eGalax Inc. USB TouchController" --t...

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

So, quick update, I got the xinput_calibrator to run (installed it, then ran "xinput_calibrator" from term window) and it gave me four points, I touched them, that worked, it gave me the output, I put it into a file (it suggested /etc/X11/xorg.conf.d/, but I did Dougie's suggestion of /usr/share/X11...

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

Are you running Raspbian Stretch? Unsure, I did a cat of /etc/os-release and it says Version 8 (jessie) does that help?

Re: Can't Rotate Full-size Touchscreen (can rotate display though)

Does it appear as an evdev device? Have you looked at xinput-calibrator? I'm not sure. How can I check if it is an evdev device and where would I find the xinput-calibrator. I did see a number of articles regarding the official RPi touchscreen, where there are lines of code in /etc/modules and /etc...

I've found a lot of posts on how to rotate the display: /boot/config.txt display_rotate=1 and how to rotate the touchscreen on the official Raspberry Pi touchscreen with lcd_rotate=2 However, I'm trying to rotate the touchscreen attached to a Raspberry Pi via a standard USB cable going into a full-s...
