The screen is garbled on Samsung Galaxy 5

[GoogleCodeExporter]

I'm running tightvncviewer on Ubuntu Linux 10.04.2 accessing the device over 
the wifi. I am able to access it but all I can see is a garbled screen as in 
the attached screenshot. The log of androidvncserver can be seen below and the 
raw framebuffer contents is also attached.

I tried several different configurations on the client side but none worked. 
Could you please help?

Try installing androidvncserver from this location:  
https://github.com/oNaiPs/droid-VNC-server/tree/master/res/raw

It is from the Android App VNC Server and clears up a similar issue in my 
device (BeagleBoard).

This might be the cause:

http://code.google.com/p/android-vnc-server/source/browse/trunk/fbvncserver.c

Line 191:   /* TODO: This assumes scrinfo.bits_per_pixel is 16. */
Line 192:   vncscr = rfbGetScreen(&argc, argv, scrinfo.xres, scrinfo.yres, 5, 
2, 2);

As you can see the screen is always initialized for 16-bit color depth. All 
devices that do not work use 32-bit depth.

Too bad this project seems to be abandoned and not maintained any more...
