does the libreELEC can control the screen rotate ?
eg: a device have 1 build-in screen. and it's a vertical screen, we need to rotate it. but however, the HDMI output do not need rotate.
libreELEC seems have no GUI, it using libdrm-gbm dedicatedly. no such X11 or wayland.
And my device is not RPI, so , have no config.txt , is there another way to console it ?
thanks
