how to configure the x-win

Tue Jul 4 04:49:57 PDT 2006

Hello, all,

i have a 16 gray scaled (4bpp) TFT VGA LCD connected with an ARM 9 processor. everything works fine on the hardware side but i got a headache when i tried to load and display the x-win in the LCD. so, does x-win supports 4bpp? as i tried to configure the depth to 4 in /etc/X11/xorg.conf and got the error message. it turned out that FBDevScreenInit() doesn't support 4bpp.

can anybody shed me some light on whether x-win will output the following data to the framebuffer?
xxxx 1111 2222 3333 xxxx 4444 5555 6666
xxxx 7777 8888 9999 xxxx aaaa bbbb cccc
.....
or 
1111 2222 3333 4444 5555 6666 7777 8888
9999 aaaa bbbb cccc dddd eeee ffff     0000
.....
or
in what format will it send to the frame buffer?

Best regards,
Inky Lung
