The unmodified drm_driver_legacy_fb_format() gives RG16 if it is asked for a 16 bit depth (and the corresponding bpp in the way that the X server does) and RG24 if asked for 24 bits. So swapping the bits around will always break one of the hardware-supported depths unless you can cross/uncross the wires dynamically when setting the frame buffer. Best regards, --Frej
