From e7434c17b4b3d984e11611ee7c2143a7b4557a67 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Sat, 8 Apr 2017 21:45:59 +0800 Subject: [PATCH] meta-yocto-bsp: workaround the X malfunction on beaglebone After the change in kernel commit a291b6b3d287 ("ARM: dts: am335x-boneblack: Add blue-and-red-wiring -property to LCDC node"), the pixel format we support for 32bit bpp has been changed from XRGB8888 to XBGR8888. But the fbdev created by modesetting driver use the XRGB8888 format by default, this causes the X malfunction. There is no easy way to adjust the pixel format of the fbdev created by the modesetting driver. So we create a xorg.conf to use the 16bit bpp to work around this issue.
