: How do I have to set SCREEN_PIXTYPE when I am using linux frame buffer and
: have an 4bpp grayscale display?
SCREEN_PIXTYPE=MWPF_PALETTE
In palette mode, colors are palette indices. 8bpp or 4bpp
they're still indices, 4bpp is 0-15, 8bpp is 0-255. The
indices are reverse-looked up in the engine/devpalX.c
tables from the application-specified RGB colors. The
index is then sent to the linked in drivers/fblin{4,8}.c driver.

Greg
