Hallo,

I have a SA1110 based board with linux-2.5.6-rmk1 running on it. On this board I am \
trying to make an ALPS monochrome LCD work, whose resolution is 240X320 and has 4Bpp.

The problem:
If I configure the LCD for 320X240 mode, I get two screens, the first one being of \
length 240 pixels and the next one being 120 pixels and two logos along with 2 \
cursors blinking, with a good contrast. Since the LCD is portrait type i.e 240X320, \
so when I make the changes to drivers/video/sa1100fb.c for this resolution, the \
penguin logo comes alongwith the cursor but within 5-10 seconds the logo fades away \
and the cursor becomes invisible.


I have struggled a lot to find the reason behind it and am stuck up on this for a \
number of weeks on this. I get the timing calculations for 320X240 only @ 70Hz but \
not for 240X320 @ 70Hz. 

Can somebody please give me pointers as to what I should look into.

Thanks and Regards....Aradhana
