Using 24bpp X11 color depth on i.MX6Q with Vivante

Hi everybody,


I've seen that by default the Vivante X11 driver is configured to use 16bpp, as can be read in the Xorg.0.log.

[4142552.927] (II) VIVANTE(0): Creating default Display subsection in Screen section
    "Default Screen Section" for depth/fbbpp 16/16
[4142552.927] (==) VIVANTE(0): Depth 16, (==) framebuffer bpp 16
[4142552.927] (==) VIVANTE(0): RGB weight 565 
[4142552.927] (==) VIVANTE(0): Default visual is TrueColor

Full log here:


If on the contrary if I specify 24bpp color depth in xorg.conf the server seems to start correctly at a first glance in the log, but then it crashes and nothing is displayed on screen.


This happens both on a fsl-image-gui built using Yocto based on BSP 4.0.0 and on the Freescale BSP 4.0.0 with Ubuntu. I'm using a Boundary Nitrogen6x board.


Is anybody else experiencing this problem? Any fix or known workaround?
