Fra Posted June 14, 2022 Share Posted June 14, 2022 Good morning, I'm using RK3328 SOM-EVB by Olimex with Armbian 22.02.0-trunk with Linux 4.4.213-rockchip64. I'm using it with an HDMI LDC 7" capcaitive touchscreen by Waveshare (https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-1/7inch-hdmi-lcd-h.htm). I can't rotate the LCD in portrait mode. In Application->Screen the "Rotation" section is "none" and there aren't any other choice (like left, right, inverted). If in command line I use: xrandr --output HDMI-1 --rotate left it gives me back: xrandr: output HDMI-1 cannot use rotation "left" reflection "none" Does anybody knows how to solve it and rotate the LCD? Thanks 0 Quote Link to comment Share on other sites More sharing options...

Good morning,
I'm using RK3328 SOM-EVB by Olimex with Armbian 22.02.0-trunk with Linux 4.4.213-rockchip64. I'm using it with an HDMI LDC 7" capcaitive touchscreen by Waveshare (https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-1/7inch-hdmi-lcd-h.htm).
I can't rotate the LCD in portrait mode.
In Application->Screen the "Rotation" section is "none" and there aren't any other choice (like left, right, inverted).
If in command line I use:
xrandr --output HDMI-1 --rotate left
it gives me back:
xrandr: output HDMI-1 cannot use rotation "left" reflection "none"
Does anybody knows how to solve it and rotate the LCD?
Thanks
