According to suggestion by Freescale the "bpp=32" parameter is required to run X in 24 bits mode. See: https://community.freescale.com/thread/309966 |
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: http://pastebin.com/V9hm03BE If on the contrary the xorg.conf is configured to specify 24bpp color depth with "DefaultDepth 24" the server seems to start correctly at a first glance in the log, but then it crashes and nothing is displayed on screen. http://pastebin.com/QPjXr0hP Tested on Boundary Devices' Nitrogen6x.
