Description Scott Bartolett 2021-08-05 21:04:58 UTC
I am trying to rotate a Qt5 application 180 degrees using the linuxfb rotation=180 setting but it seems to be ignored.  I've tried other linuxfb options such as offset but these also seems to be ignored.  Are these options supported under buildroot?

I've tried:

./test -platform linuxfb:fb=/dev/fb0:rotation=180
./test -platform linuxfb:rotation=180
./test -platform linuxfb:fb=/dev/fb0:rotation:180

I've also tried setting teh environment varaible QT_QPA_PLATFORM.  But in all case the application to runs normally (not rotated).

I did find this patch: https://borkedlabs.com/blog/2015/06-01-qt5-linuxfb-rotation-for-lcds/, but it is from 2015 so I would assunme this issue would have been fixed by now.
