[Linux-fbdev-users] Problem of fading of Linux logo in portrait mode

[Aradhana P. <ara...@wi...>]

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.=20

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

Thanks and Regards....Aradhana
