Problem while starting Xfbdev

[Prashant J Zaveri]

We want to run Xfbdev on a ARM-Linux based embedded system. Our environment is:

Board: ARM9 core, Freescale i.MX21 processor based board
Kernel: 2.6.22 vanilla with a few board specific patches
LCD: 240x320, 3.5" from Toppoly TD035STEB1
LCD Interface: 16-bit color

Linux is running fine with framebuffer and is using LCD as console.

I have cross-compiled Xfbdev and its dependencies successfully. Following
command was then executed to start Xfbdev:

       Xfbdev -screen 240x320x16 -dpi 113 -rgba rgb

Xfbdev seems to start and prints the following:

       Warning: mode not found, using default

At this point the LCD starts flickering and we see horizontal lines running from
bottom to up on the LCD.

What is the problem here? Are there any important arguments that I
am missing?

Is there any debug mode for Xfbdev where in it prints or logs more
messages while
starting?
