Screen Auto-Rotation on Linux 6.1 for i.MX8MQ

[Derek0902]

Hi,

I have a i.MX8MQ based custom board and its OS is Linux 6.1. Then I have ported STM LSM6DSV IMU on i.MX8MQ. If I want to make screen auto-rotate with IMU, how can I do it? Is there any reference I can refer to it?

Thanks & Regards,

Hi @brian14 ,

BTW, I can modify /etc/xdg/weston/weston.ini to rotate the screen. But it needs to reboot the board again to init the screen orientation.

I want to change screen orientation dynamically, Is there no command I can use?

I found some information that there is a config file under /tmp/.weston_drm.conf from website. The file can config screen orientation dynamically, but I found that there is no config file on imx8mq.

Thanks & Regards,

Derek Lin

Hi @Derek0902, 

Please have a look to the i.MX Graphics User's Guide chapter 2 i.MX G2D API.

Hi @brian14 ,

When I compile C program, it can't include "g2d.h". Is i.MX8MQ supported g2d API?
