What I saw was 1280x720 properly negotiated at boot time (the Yocto splash used 1280x720), but when X started, it requested a mode change to 640x480. In fact, if I stop X with "/etc/init.d/xserver-nodm stop", the resolution goes back to 1280x720. > I have seen a similar problem back then with both framebuffer and X11. > It was the reason for the cea mode patch in the cubox-i kernel (the > patch is included in meta-fsl-arm-extra).

We also allow non-CEA modes, but have a separate flag to disable them (mxc_hdmi.only_cea). The reason for this is that the HDMI audio channel is not clocked properly for non-CEA modes. Our default boot script disables non-CEA modes by default: https://github.com/boundarydevices/u-boot-imx6/blob/production/board/boundary/nitrogen6x/6x_bootscript-yocto.txt#L111 The reason I say this is perhaps related is that our Nitrogen6X-Lite board didn't have this flag set in its boot script, and negotiated an 1152x864 resolution. When it did, the X startup **did not** revert to 640x480. Regards, Eric
