It wont work as imx8mm xwayland doesnt have support of gnome-shell.

This issue is crucial to our project. I request NXP support team to provide us a lead.

Have you try xrandr command?

I found xrandr doesnt work when we using xwayland image. Only weston utilities works, x11 doesnt.

Hi all,

I have a QT application running. I want to rotate display direction without restarting the weston as It will abrupt my running QT application. 

Please provide me a lead.

Hi all,

I am using IMX8MM with yocto 5.4.70 xwayland. I want to rotate display on the fly means without restarting weston service by making changes in weston.ini. Can someone will provide a lead?  Mayo Clinic Portal

Hello,

To achieve on the fly display rotation without restarting the Weston service on an IMX8MM platform running Yocto 5.4.70 with XWayland, you can use the Weston's `weston-transform` tool. This tool allows you to manipulate the transformation properties of an output while Weston is running.

For example, to rotate the display 90 degrees clockwise, you can use the following command:

weston-transform -r 90

Replace `90` with the desired rotation angle. Make sure to specify the correct output name if you have multiple outputs. 

By utilizing `weston-transform`, you can dynamically apply display rotation without needing to modify the weston.ini configuration or restarting the Weston service. This is useful for situations where you need real-time adjustments to the display orientation. 

If this information helps you, please mark the answer as the best.

Hi @Allisonsnyder ,

There is no utility on imx8mm as weston-transform. I found weston-transformed but it doesnt have rotation as parameter.

**************************************************************
root@imx8mmevk:~# weston-transformed -r 90
Usage: transformed [OPTIONS]

-w <width> Set window width to <width>
-h <height> Set window height to <height>
--help Show this help text

This version has been fixed for https://gitlab.freedesktop.org/wayland/weston/issues/99 .

**************************************************************

It basically created black screen on of WxH dimension. Anything else I can try out?

Thanks,

Ajita
