    <thetext>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  
        &quot;Default Screen Section&quot; 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 the xorg.conf is configured to specify 24bpp color depth with &quot;DefaultDepth 24&quot; the server seems to start correctly at a first glance in the log, but then it crashes and nothing is displayed on screen.

Tested on Boundary Devices&apos; Nitrogen6x. Tested BSPs: 3.0.35-1.1.0; 3.0.35-4.0.0; 3.5.7-1.0.0

    <thetext>According to suggestion by Freescale the &quot;bpp=32&quot; parameter is required to run X in 24 bits mode.
