With help from libvncserver and droid-vnc-server, I could load VNC server daemon running on the android.
So far, I tried in Nexus 7, Galaxy Tab 3 (10.1 x86), Galaxy prevail, Nexus 4, Galaxy S3.
Only in galaxy prevail returns a screen installed by libvncserver. I think libvncserver does not deal with 32 bpp.
Whereas droid-vnc-server runs fine in Nexus 7 and Galaxy Tab 3 but once I try to connect to VNC server, the server returns only black screen.
It looks like the problem is that rfb is not correctly getting framebuffer.
Nexus 7 has Tigra and Galaxy tab 3 uses raw fb0 (YAY x86!!)
Did anyone successfully run droid-vnc-server ????
