Hello,

I've met a problem on i.MX6 with weston, here are some information,

yocto build commands are:

DISTRO=fsl-imx-xwayland MACHINE=imx6solosabresd source fsl-setup-release.sh -b build-xwayland
bitbake fsl-image-qt5-validation-imx

And I can see a window as the attachment shows,

So why doesn't  "transform=90" work?

Please help, thank you.

Yes, It works with weston.

Thank you.

[liqun_wei]

Doses anyone have this problem, when setting transform=90 or transform=flipped-90, the display always shows the same

normal window without rotation.

Hello liqun,

The weston.ini enables a rootless xwayland.so in weston. 
The [output] section with name=X1 defines weston's appearance as X client.

• mode=1024x600 sets the screen/window size.
• transform=90 rotates the weston display.
• scale=1 sets a scaling factor if needed.
• the [launcher] sections can be used to create custom panel starters for your X applications.

(Instead of using the weston panel, you can disable it with panel-location=none, parse output of weston for xserver listening on display :1 and use DISPLAY=:1 yourXapp)

Remember that rotation involves IPU.

Regards
