Touchscreen 90 degrees wrong aspect ratio

Wed Feb 21, 2018 2:16 pm

Normally I should write "lcd_rotate=1" into "/boot/config.txt" and the screen should be rotated 90 degrees. But sadly this is not working. So I figured out a workaround. I used "display_rotate=1". That works fine, but this doesn't turn the touch area. So I found out how to turn the touch area too. With the following command the touch area is rotated 90 degrees:

Code: Select all

DISPLAY=:0 xinput --set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1
Perfect, so far. Took me only several days and made me a little bit more crazy. Super complicated. If "lcd_rotate" would work, I could've safed A BIG BUNCH of time. Anyway. Now the screen aspect ratio is not perfect. You can see it with the round icons, they are not round, more like a egg. Can someone give me a workaround for this? I attached a screenshot and drew a red circle around the raspberry icon. It's not so obvious, but the bigger the image, the more you can see it.

I took another photo of the screen showing a circle. It's obvious that the screen doesn't show the image in the right aspect ratio. But how to fix that? It's the official raspberry screen. There should be a solution for this. If no one knows help, where can I get help directly form the Raspberry crew? Maybe a link where I can open a support ticket would be great. But right now the screen is not working how it should be.
