But when I try to calibrate with the display up then I see only issues without any systematic diagnosis. Touch simply does not react at all!!! Or leads the cursor to the edge.
When I plug screen in, it works, but only covers about 80% of the screen. The right-most 20% is blank. No matter what changes I put in (that I read on this forum), the display will not fill in the right side.
Still, somehow the "InvertX" and "InvertY" options seem to have no effect - fortunately the "SwapAxes" option was enough to fix this in my case. Mind that in my case the other proposed option "SwapXY" seemed to have no effect to...
1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:
You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.
4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:
When it comes to quotations and quotation marks, each language has its own symbols and rules. For this reason, several LaTeX packages have been created to assist in typesetting quotations in-line, in display mode or at the beginning of each chapter. It"s important to remark that even if you are typing English quotes, different quotation marks used in English (UK) and English (US). Plenty of different quotation marks can be typeset with LaTeX, and there are options for almost every language (see the reference guide).
The csquotes package provides advanced facilities for in-line and display quotations. It supports a wide range of commands, environments and user-definable quotes. Quotes can be automatically adjusted to the current language by means of the babel or polyglossia packages. This package is suitable for documents with complex quotation requirements, therefore it has a vast variety of commands to insert in-line quotes, quotes with sources, block-quotes with the support of changing language.
