I turned on Apple Remote Desktop on my MacBook Pro, but I couldn't VNC into it from my Linux box. However, I could VNC into it from my Solaris 9 box, and from my Mac at home (the one that mattered) with Chicken of the VNC 2.0b2. All Macs running 10.4.10. Linux gave me an unknown message type 242.
Here's what I saw on Linux (2.6.9.55 RHEL4AS):
vncviewer 1.2.3.39

On the other hand, here's what I saw on Solaris 9:
vncviewer 1.2.3.39
VNC server supports protocol version 3.889 (viewer 3.3)
Password:
VNC authentication succeeded

Using default colormap which is TrueColor. Pixel format:
32 bits per pixel.

True colour: max red 255 green 255 blue 255, shift red 0 green 8 blue 16
So if I can use something other than Linux, my VNC viewer to Apple Remote Desktop works. I wonder if Linux is just using a newer version (RFB remote frame buffer protocol version 3.8 instead of 3.3) ... but (intelligent!) backwards compatibility would be nice! I really didn't troubleshoot any further than this because it was Friday evening, and I could go home if I had reasonable confidence that I could VNC in to my MacBook Pro. Since Solaris worked, I didn't much care why Linux failed. Sure enough, my Mac at home also worked, so I went about finishing that long task, and enjoying my precious weekend.
Update: solved 10/02/2007!
