Weston dual screen issue at imx8
Hello,
I am using imx8 bases custom board which has one HDMI and one LVDS display port. I am trying to clone display using weston 9 patch.clone-from-LVDS-to-HDMI.patch
I have modified weston.ini file
[output]
name=DPI-1
mode=1280x800
[output]
name=HDMI-A-1
clone-from=DPI-1
Currently both display’s supported modes:-
root@imx8mp-cgtqx8p:~# cat /sys/class/drm/card1-DPI-1/modes
1280x800
root@imx8mp-cgtqx8p:~# cat /sys/class/drm/card1-HDMI-A-1/modes
1920x1080
1920x1080
1920x1080

1280x1024
1280x1024
1280x960
1152x864
1280x720
1280x720
1280x720
1280x720
800x600
800x600
720x576
720x480
720x480
720x480
720x480
My primary display is LVDS, and we need to clone in our secondary display that is HDMI. We have custom resolutions of LVDS : 1280x800. But this resolutions is not there in HDMI edid display data.
On HDMI after cloning it takes some default resolution from HDMI available modes. So how can we achieve clone as per our custom LVDS resolutions?
on my other imx6 board LVDS : 800X480 cloning is working fine. issue occurs on imx8 board.
